San Francisco uses at least thirteen different starting pitchers in the 2026 regular season.

San Francisco records three or more relief appearances of four or more innings across its final fourteen regular-season games, September 12 through September 27, 2026.
Across every regular-season start Logan Webb makes for San Francisco from September 14 through the end of the 2026 regular season, he is charged with more earned runs in the first three innings combined than in every inning from the fourth on combined.
Logan Webb is credited with 30 or more starts in the 2027 major league regular season.
Cesar Perdomo and Yunior Marte each start at least one of San Francisco's final six regular-season games, September 21 through September 27, 2026.
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.

San Francisco placed Logan Webb on the 15-day injured list on September 18 with a right middle finger blister and shut him down for the season, ending a year in which he made 27 starts and threw 160 2/3 innings at a 4.31 earned run average. It is his second injured list stint of 2026; he did not start for 20 San Francisco games in May with right knee bursitis. The 160 2/3 innings end a run of three straight seasons above 200, and two more starts at this year's rate would have left him near 172. His innings per start has fallen in each of the three seasons since 2023: 6.55, 6.20, 6.09, 5.95. Over his last five starts he allowed 23 earned runs in 21 2/3 innings. Landen Roupp has already made more starts than Webb this season, the first time anyone on the club has since 2021, and needs six innings across his remaining turns to pass him in innings as well. Hayden Birdsong, Trevor McDonald and Carson Whisenhunt are all on the club's injured list rehabbing from Tommy John surgery. One take filed.

Logan Webb has a 4.31 earned run average in 27 starts for the Giants in 2026, up from 3.22 in 34 starts last season, and the damage is concentrated in two innings. He has allowed 38 of his 77 earned runs in the second and third innings, which is 49 percent of the runs in 33 percent of his innings. His combined earned run average in those two innings was 2.95, 2.94, 2.32 and 3.31 in the four seasons before this one; this year it is 6.49. From the fifth inning on he has allowed 11 earned runs in 57 innings, an earned run average of 1.74, the lowest of his career by that measure. He allowed fewer hits per nine innings and posted a better opponents' on-base plus slugging than in 2025. He made his third straight All-Star team in July after a June in which he gave up three earned runs in 38 innings. One take filed.

San Francisco selected the contract of left-hander Cesar Perdomo from Triple-A Sacramento on September 1 and he made his major league debut the same afternoon at Pittsburgh, pitching the fourth through the seventh innings of a 13-12 loss. Perdomo faced fifteen batters, recorded twelve outs, allowed three hits and one run, walked one and struck out four, throwing 40 of 58 pitches for strikes. Logan Webb started and was charged with nine earned runs while recording six outs against eighteen batters faced. Perdomo is 24, signed as a free agent out of Venezuela on July 2, 2021, and did not appear in a professional game until June 2022, when a 60-day injured list stay ended his first season after fifteen innings. He did not reach a full-season league until April 2024 and was assigned to Double-A Richmond on April 1 of this year, five months before his debut. His Sacramento line was a 5.10 earned run average with 20 walks in 47 and two-thirds innings. The 40-man spot came from Adrian Houser, moved to the 60-day injured list the same day with a right forearm strain and a club-stated expected return of 2027. San Francisco also recalled catcher Zach Morgan, who has still never appeared in a major league game. Two takes filed.

San Francisco's schedule from Friday to Monday asks for four starting pitchers. Blade Tidwell is the only one named. Saturday is a split doubleheader at Oracle Park, moved off Sunday on June 23 to clear a travel day for the makeup of a June 18 rainout in Atlanta, which is now Monday. Ten men have started a game for the Giants in 2026; Robbie Ray and Tyler Mahle were traded, Trevor McDonald and Carson Whisenhunt are on the 60-day injured list, Adrian Houser went on the 15-day list Wednesday, JT Brubaker is on the 15-day list, and Matt Wilkinson was optioned to Sacramento on August 24. That leaves Logan Webb, Landen Roupp and Blade Tidwell, and all three are already spoken for. The club is carrying thirteen pitchers, which is the most the rules allow before September 1, when the active roster goes to 28 and the pitcher limit to 14. The doubleheader lets it add a 27th man for one day, and that exception is the only way Wilkinson pitches in the majors before September 8. Two takes filed, on the 27th man and on the length of the four starts.

Major League Baseball awarded San Francisco the 2028 All-Star Game on Friday, the city's fourth and its first at Oracle Park since 2007. The Giants are 50-72 and spent the deadline turning veterans into prospects. Four of their five Baseball America Top 100 prospects are in Single-A or below, and on the reported date of the game the two that shop ranks highest will be 20 and 19 years old. The men actually under contract that summer are Rafael Devers, Willy Adames, Matt Chapman and Logan Webb, and Webb's deal expires that year.
