Deadline math

Luis Arraez Is Worth What He Looks Like. Robbie Ray Is Worth 1.3 Runs Less.

The Giants are sellers at 0.4 percent, and that part is settled. What is not settled is the price on their two expiring contracts, where the underlying numbers point in opposite directions.

Every call on this site goes on a public ledger and gets graded. The misses stay up.

The Giants' playoff odds are 0.4 percent.

That is FanGraphs. Baseball Prospectus has them at 0.3. Baseball Reference has them under 0.1. Three models built on different assumptions, run against a 44-60 team sitting 10.5 games out of the last wild card with 58 to play, and they agree to within a rounding error. There is no version of the rest of this season worth playing for.

So the interesting question is not whether the Giants sell before 6 p.m. Eastern on August 3. It is what they are selling, and there the numbers are much less agreeable.

Two players are on expiring contracts and are plainly available. Luis Arraez, one year at $12 million, no no-trade protection, hitting .326. Robbie Ray, the last year of the five-year deal he signed with Seattle, roughly $8 million left on it, carrying the best ERA in the rotation. Both look like sell-high candidates. Only one of them is.

Arraez has been the Giants' best player, and it is not close

FanGraphs WAR, position players and pitchers together, 2026 season through July 26. The two highlighted names are the expiring contracts. One of them leads the team. The other is ninth on it.

Look at where the two highlighted rows sit. Arraez is at the top of a chart that contains the entire roster. Ray is ninth, below a 21-year-old who has been in the major leagues since May.

The gap in Ray's line is the whole story#

Ray has a 3.34 ERA. He also has a 4.66 FIP, which is Fielding Independent Pitching, the estimate of what a pitcher's ERA would be if you stripped out everything his defense and his luck did and kept only the four things he controls without help: strikeouts, walks, hit batsmen and home runs.

The gap between those two numbers is 1.32 runs. He is the only starter in the rotation whose FIP is worse than his ERA, and every other starter's gap runs the other direction.

Ray owns the rotation's best ERA and its second-worst FIP

Bar length is FIP, so longer is worse. Actual ERA at right. Every Giants starter except Ray has a FIP lower than his ERA, which is the ordinary direction for a pitcher whose results are being earned rather than allowed.

Adrian Houser66.0 IP
5.335.73 ERA
Robbie Ray110.1 IP
4.663.34 ERA
Tyler Mahle83.0 IP
4.525.31 ERA
Trevor McDonald70.1 IP
4.275.12 ERA
Logan Webb113.0 IP
3.503.98 ERA
Landen Roupp110.0 IP
3.313.93 ERA

The mechanism underneath is not mysterious. Ray is walking 11.6 percent of the batters he faces and striking out 19.9 percent of them. A pitcher who walks that many people and misses that few bats is not usually running a 3.34. The strikeout rate is the part that should worry a buyer most, because it is the most stable thing on a pitcher's page and it stabilizes fastest. It says this is who he is now, at 34, in his walk year.

None of which means Ray is worthless. He has made 20-plus starts, he is durable, he is left-handed, and a contender that needs a fourth starter in October will pay for that. It means the price a buyer quotes off the ERA is a price the Giants should take immediately and without negotiating, because the components say the next 58 games are more likely to look like the FIP than the ERA.

Arraez is the opposite case, and the reason is his glove#

The batting line is the part everyone can see: .326/.363/.449 in 433 plate appearances, a 122 wRC+, which means 22 percent better than a league-average hitter after adjusting for park and era. That is a good season and it is roughly the season Arraez always has. Three batting titles say so.

The part that has actually changed is the defense.

Arraez is at plus-11 Outs Above Average at second base, a career best, second among all second basemen behind the Cardinals rookie JJ Wetherholt. For most of his career the glove was the thing you tolerated to get the bat. This season it is an asset, and that single reversal is doing more to his trade value than the batting average is.

That is also why the 3.7 WAR is real rather than a fluke of sequencing. It is built out of two independent components moving in the same direction, one of which is measured by cameras rather than inferred from outcomes.

The honest caveat: single-season defensive metrics are the noisiest thing in this piece. One year of OAA is not proof that a 29-year-old has permanently become a good defender. It is evidence, it is better evidence than the reputation it contradicts, and a buyer should still discount it more than they would discount the bat.

The part no deadline can fix#

Both of these men will be somewhere else in August, and it will not change the shape of this franchise, because the actual problem is not on the expiring-contract list.

Willy Adames is signed through 2031 at $26 million a year, with roughly $140 million left after this season, and he is hitting for a 93 wRC+ with 0.1 WAR. Matt Chapman is signed through 2030 with about $100 million left, at a 95 wRC+. Both hold full no-trade clauses. Those two facts in combination, negative surplus value and an absolute veto, are what make a contract genuinely immovable rather than merely expensive.

Rafael Devers is the interesting exception, and he is interesting in the direction nobody expects. He has no no-trade clause, which makes him the only one of the three the Giants could actually move. He is also, since the start of May, hitting well enough that they should not want to. The 22 homers and the 119 wRC+ are the current numbers. The .232 average and 79 wRC+ that still circulate are from May 11, when this team was 16-24, and they describe a player who no longer exists.

There is a column somewhere arguing that this roster needs to want it more. This is not that column, and the payroll ledger is not interested in that argument either.

What this piece is predicting#

Three calls, all of them scoreable by anyone holding a box score in October.

Ray finishes 2026 with a season ERA above 4.00. Neither Adames nor Chapman is traded by the August 3 deadline. And Arraez is traded, in a deal whose headline return does not include a consensus top-100 prospect, because a 29-year-old rental second baseman with one year of contact-first offense and one year of good defense is not what that price buys.

Method

All rate stats and WAR figures are FanGraphs, team pages retrieved July 26, 2026, and reflect games through July 25. Outs Above Average is Statcast. Playoff odds are FanGraphs, Baseball Prospectus PECOTA and Baseball Reference as of the same date and are model output, not measured results. Contract terms and remaining money are per MLB Trade Rumors. Known weaknesses: single-season OAA carries the widest error bars of any number here, and the two public estimates of Arraez's wRC+ this week differ by three points depending on the cutoff date, which is a date artifact rather than a disagreement.

The Giants made five trades in two days. Graded on August 3, one of them is a C+

A process grade asks whether a club made the right trade at the right price at the right time on what it knew that day, and the answer does not change when the players do. The five Giants deadline trades, graded as of August 3, 2026: Tyler Mahle to Atlanta for Anthony Molina, C+; Luis Arraez and Caleb Kilian to Philadelphia for Ramon Marquez and Marty Gair, A-; Robbie Ray to San Diego for Miguel Mendez and Joniel Hernandez, B+; Heliot Ramos to New York for Henry Lalane and Kaeden Kent, B; Erik Miller and Carlos Gutierrez to Boston for Marcelo Mayer, A-. Every source is dated August 2 to August 4. The result gets its own grade when the season ends on September 27.

Four pitchers would cost the Giants no draft pick, and the youngest is 30

Freddy Peralta, Clay Holmes, Kevin Gausman and Robbie Ray changed clubs at the deadline, so signing any of them costs the Giants no draft pick; they are 30 to 35, and two walked batters at a higher rate than the Giants' staff, sixth-highest in the majors. The four lower-walk arms can carry a qualifying offer, and their clubs decide by Monday, Nov. 2, the same day the Giants must cut their 40-man roster by 11.

Posey starts the winter with the bullpen, and the rotation lost more

At the season-end news conference on September 29, Buster Posey took the blame for the bullpen and said the club's offseason work starts there, with the rotation right behind it. The 2026 record explains why the bullpen is first in line: 16-29 in one-run games, and a relief corps whose strikeout-minus-walk rate beat only two clubs. The 2027 supply says the rotation has the bigger hole. Of 162 starts, 39 went to Robbie Ray and Tyler Mahle, both traded at the deadline, and 31 went to Trevor McDonald, Blade Tidwell and Carson Whisenhunt, whose elbows put their returns at late 2027 or 2028. The lineup the club intends to keep drew 449 walks, the fewest in the majors, and owes $451 million from 2027 on to Rafael Devers, Willy Adames and Matt Chapman. The same week, MLB Pipeline named San Francisco its Farm System of the Year. No take filed.

Seven of the thirteen men who started for the Giants cannot pitch this week

Thirteen pitchers started a game for San Francisco in 2026. Seven of them are unavailable for the final homestand: Tyler Mahle was traded to Atlanta on August 2 and Robbie Ray to San Diego on August 3, while Trevor McDonald, JT Brubaker, Carson Whisenhunt, Adrian Houser and Logan Webb are all on the injured list. Those seven made 105 of the club's 156 starts, or 67.3 percent. Measured the same way on the same morning, with all thirty clubs carrying 28-man active rosters, that is the highest figure in the major leagues; the league median is 27.2 percent and Toronto is second at 50.0. The six starters still standing are Landen Roupp (29 starts), Blade Tidwell (8), Matt Wilkinson (5), Anthony Molina (4), Cesar Perdomo (3) and Yunior Marte (2), for six games in seven days. Wilkinson threw five scoreless innings at Dodger Stadium on Sunday with a career-high six strikeouts in a 3-1 loss. Tidwell starts against Minnesota tonight. One take filed.

On the record

Called Shots →
Held upJul 26, 2026

Neither Willy Adames nor Matt Chapman is traded by the August 3, 2026 deadline.

Resolved 2026-08-03: CORRECT. Neither was traded. Both Willy Adames and Matt Chapman remain on San Francisco's 40-man roster, verified at the club's live roster feed. Scored 2026-08-05 by CP against the league's official transaction feed for teamId 137 (statsapi.mlb.com/api/v1/transactions, 08/02-08/04) and the club's live 40-man roster. Two days late, and the lateness is the desk's, not the writer's: the site published nothing from 2026-08-02 through 2026-08-04 and nobody scored the ledger on the night it resolved. The five deadline trades of record: Mahle to Atlanta for Anthony Molina (Aug 2); Arraez and Caleb Kilian to Philadelphia for Marty Gair and Ramon Marquez; Erik Miller and Carlos Gutierrez to Boston for Marcelo Mayer; Robbie Ray to San Diego for Miguel Mendez and Joniel Hernandez; Heliot Ramos to the Yankees for Henry Lalane and Kaeden Kent (all Aug 3). PRIOR NOTE FOLLOWS. Both hold full no-trade clauses and both are producing below league average, Adames at a 93 wRC+ with 0.1 fWAR and Chapman at 95. Negative surplus value plus an absolute player veto is what makes a contract immovable rather than merely expensive. The Giants were reported in June as open to offers on both, which is what makes this falsifiable rather than obvious.

The Giants removed 17 players from their 40-man roster between Oct. 29 and Nov. 2 and now hold exactly 40. They must add any prospect they want to shield from the Rule 5 draft by Nov. 17, three days before the Nov. 20 tender deadline, with Henry Lalane first in line and three pitchers holding spots they are not expected to use before late 2027 at the earliest.

Brian Sabean said he was not an idiot. Jeff Kent repeated it in Orlando

On Wednesday, November 13, 1996, Brian Sabean, newly named general manager of a Giants club that had finished last at 68-94, traded Matt Williams to Cleveland for Jeff Kent, Jose Vizcaino and Julian Tavarez. Two days later he called an informal news conference and said, per the San Francisco Chronicle, \"Well, I'm not an idiot.\" Kent drove in at least 101 runs in each of his six seasons in San Francisco, won the 2000 MVP and was elected to the Hall of Fame by the Contemporary Baseball Era Committee on December 7, 2025. At his introductory news conference the next day he said he would not be in the Hall without the trade and repeated Sabean's line. Sabean, the longest-serving general manager in franchise history, is on the Contemporary Baseball Era ballot the committee takes up on December 6, 2026.

Three of the eight names on the Hall of Fame's Contemporary Baseball Era ballot, announced November 2, ran the Giants: Dusty Baker, Bruce Bochy and Brian Sabean. Each of the sixteen voters may name at most three candidates and election takes twelve, so electing all three Giants on December 6 would use 36 of the room's 48 votes.

Bobby Thomson played third base in the New York Giants' last home game at the Polo Grounds and was a Chicago Cub before their first game at Seals Stadium. Seventy-five years after his home run won the 1951 pennant, the bat is in Cooperstown, the ground is under public housing in Harlem, and a New York society keeps the memory of a team that still plays. San Francisco holds the pennant. Its own record says it has done best by the home run when it traveled east as a guest.

San Francisco Used The Same Roster Spot For Two Major League Debuts On Saturday

San Francisco handed out two major league debuts on Saturday, eight hours apart, and used one active-roster spot to do it. Seth Lonsway, 27, threw two innings of relief in a 7-1 loss in the first game and was optioned to Triple-A Sacramento between games so the club could add Yunior Marte, a 23-year-old right-hander promoted directly from Double-A Richmond. Marte started the second game and gave up one run in four and two-thirds innings of a 7-2 win. He had thrown 291 professional innings before Saturday and none of them at Triple-A. The 40-man spot came from Casey Schmitt, moved from the 10-day to the 60-day injured list with a left knee meniscus tear he has carried since July 28. Marte is the eleventh man to start a game for the Giants in 2026 and the fourteenth to debut for them, a figure MLB.com's Maria Guardado reports is second in the majors behind the White Sox. Six of the fourteen came between April 1 and June 26, none in July, and eight in August. Two takes filed.

The Giants Have One 40-Man Spot Left. December 1 Is What Makes It Expensive.

Counted entry by entry Thursday morning: 45 names on the Giants' 40-man roster, six on the 60-day injured list, 39 against the limit, one spot open. Two contracts have been selected in the last six days and neither was a prospect decision. What a September call-up costs in a year when two labor agreements expire at different times, and the part of it nobody outside the building can see.
