Seattle Mariners manager Scott Servais confirmed that rookie right-hander George Kirby will start Game 3 of the American League Division Series on Saturday against the Houston Astros. It means that left-hander Robbie Ray, who gave up the game-winning, walk-off home run to Astros outfielder Yordan Alvarez in Game 1 on Tuesday, will not make a start in this series. Kirby looked good in his first 25 major-league starts during the regular season for the M's, going 8-5 with a 3.39 ERA (2.99 FIP), a 1.21 WHIP and a 133:22 K:BB in 130 innings pitched. He made one start against the Astros in 2022, allowing two earned runs on four hits while walking one and striking out seven in four innings pitched in a no-decision.

Seattle Mariners starting pitcher George Kirby did not have his characteristic strong command Thursday, as he walked more than one batter for the first time in his career. Kirby gave up five runs on seven hits and three free passes while recording just seven outs. He struck out one. This was also the shortest outing of Kirby's career, and it raised his ERA and WHIP to 3.30 and 1.18 with 124 strikeouts in 120 innings this year. Despite the road bump, he has been extremely impressive in this rookie campaign, and he should be in high demand heading into 2023 fantasy drafts.

Seattle Mariners starting pitcher George Kirby had a nice night at the office on Saturday, although he was saddled with the loss as his team fell to the Angels 2-1. He allowed two runs on four hits and a walk in the 84-pitch performance, striking out eight batters on the night. Kirby allowed an RBI double to Shohei Ohtani in the first inning, and an RBI groundout in the fourth which ended up being the only two innings that he would allow a base runner. The 24-year-old has been impressive in his rookie season by sporting a 2.98 ERA, 1.12 WHIP, and 123 K through 117 2/3 IP as he'll look to keep it going in his next start versus the Athletics.

Seattle Mariners starting pitcher George Kirby was superb on Saturday by allowing just one unearned in a 3-1 win over the Braves. The win improves his record to 7-3 on the season as he allowed just three hits (all singles) and no walks with six strikeouts over six frames of work. Kirby worked into the seventh but was lifted after a single and error that led to the only blemish on the road side of the scoreboard. The 24-year-old rookie now owns a stellar 2.98 ERA and 1.14 WHIP with 115 K through 111 2/3 IP as he sets his sights on a matchup with the Angels next weekend.

Seattle Mariners starting pitcher George Kirby was sharp in his return from the minor leagues Tuesday night, allowing no runs on two hits and one walk in five innings. He struck out four batters and was in line for the win before the bullpen gave up the lead. Kirby was not in the minors because of any kind of poor performance, as he's recorded a 3.50 ERA and 1.20 WHIP with 66 strikeouts in 69 1/3 innings this year, but the Mariners are clearly aware of managing his innings, which could be an issue for fantasy managers as the year progresses.

The Seattle Mariners have recalled right-hander George Kirby from Triple-A. He will be the team's starting pitcher for Tuesday's game against the Texas Rangers. To clear a roster spot for Kirby, the team optioned fellow right-hander Matt Brash to Triple-A. Kirby has had an up-and-down first tour of the majors this year. Across 12 starts, he's gone 2-3 with a 3.78 ERA and a 1.24 WHIP. He's been hit hard on multiple occasions, but he's done a good job of limiting walks, as shown by his 6.9 K/BB ratio.

Seattle Mariners rookie right-hander George Kirby is tentatively scheduled to start the team's fourth game of the second half of the season against the Texas Rangers next Monday. Left-hander Tommy Milone should now serve in a more traditional relief role to open the second half of the year. Kirby will make an abbreviated start for Triple-A Tacoma on Saturday before he rejoins Seattle's rotation on Monday. The M's are looking to limit the 24-year-old's innings this year, as he's already tossed 89 innings in the majors and minors in 2022. In his first 12 starts in the big leagues, Kirby has a decent 3.78 ERA, 1.24 WHIP, 62 strikeouts and nine walks in 64 1/3 innings pitched.

Seattle Mariners starting pitcher George Kirby took his second loss of the season Thursday against the Los Angeles Angels, but he performed well, allowing just two runs on six hits and a walk in six innings. He struck out six batters. The only mistake Kirby made was leaving a fastball down to Mike Trout in the third inning that Trout promptly deposited over the outfield fence for a two-run home run. Through eight starts, Kirby has a 3.56 ERA and 1.14 WHIP with 41 strikeouts in 43 innings. He should be rostered in all keeper and dynasty formats, and is worth a look in good matchups for redraft.

Seattle Mariners starting pitcher George Kirby came back to earth in his second career start on Saturday, allowing three runs in four innings in the no-decision. Only one of the runs was earned, however, as he surrendered three hits and a walk while striking out one in the 89-pitch performance. The 24-year-old held his own against a difficult lineup, so managers should come away from this game with a positive feeling despite not matching his seven-strikeout outing from last weekend. The Mariners will likely cap Kirby's innings and pitch count this season, but he should be rolled out in starting lineups for his next start versus the Red Sox.

The Seattle Mariners are calling up top prospect starting pitcher, George Kirby. Kirby is a strong right-handed pitcher who has posted a 2.34 ERA with 137 strikeouts across 115 1/3 innings pitched in the minors. He is a must-add in all formats and should slot into the rotation for Matt Brash who was recently sent down to AAA. Kirby is expected to start Sunday vs. the Tampa Bay Rays, which offers the potential for a ton of strikeout upside.
