George Kirby Fantasy Stats

All in all, Seattle Mariners starting pitcher George Kirby has been one of MLB's most consistent right-handers since making his MLB debut in 2022. However, the 28-year-old had his first taste of real adversity in 2025. Kirby opened the year on the Injured List due to a shoulder issue that ultimately delayed his season debut until late May. Upon his return, Kirby pitched to a 10-8 record with a 4.21 ERA, 1.19 WHIP, and 137 strikeouts in 126 innings (23 starts). Kirby's strikeout rate soared to a career-best 26.1%, but he also allowed the highest opponent hard-hit rate (43.9%) of his career. Still, there's plenty of reason to think Kirby can regain his top-end form in 2026. While his walk rate spiked from 3.0% in 2024 to 5.5% in 2025, Kirby remains one of baseball's best command artists and could easily return to his career WHIP mark of 1.11. If he can hold some of the strikeout gains he made in 2025 while seeing a bit more batted ball luck, Kirby could post an ace-level season for fantasy managers.

The Seattle Mariners and right-hander George Kirby have agreed to a $6.55 million contract for 2026 to avoid arbitration, according to MLB insider Robert Murray. In 2025, Kirby went 10-8 with a 4.21 ERA (3.39 SIERA) while recording 137 strikeouts in 126 innings. Most notably, the 27-year-old, long known as a command-focused pitcher, posted a career-high 26.1% strikeout rate last year. Although right-shoulder inflammation sidelined him for nearly three months at the start of the year, he is expected to be fully healthy for the 2026 season. From a fantasy perspective, Kirby has the potential to be a top-10 starting pitcher if he can remain healthy and maintain a strikeout rate above 25%. That said, to guard against any lingering shoulder issues, it would be wise to hedge your bet by drafting a few more reliable starting pitchers.

Seattle Mariners right-hander George Kirby will start the fifth and deciding game in the American League Division Series against the Detroit Tigers at T-Mobile Park on Friday, according to Shannon Drayer. Kirby will be opposed by Cy Young candidate Tarik Skubal for Detroit. The 27-year-old Kirby is looking for a second straight strong performance to close out the series after he held the Tigers to two earned runs while striking out eight over five innings in Game 1 of the series. Kirby also faced Detroit back on July 12 and didn't fare as well, allowing four earned runs on five hits (one homer) while walking three and striking out six in five innings in a game that he ended up winning. Kirby will have to be on his game against the dominant Skubal, but he definitely has the skills to do so. If Kirby isn't on his game, right-hander Luis Castillo is probably available early in the game to help pick up the slack.

Seattle Mariners starting pitcher George Kirby was dominant on Sunday in an 11-2 win over the Angels, allowing two runs on three hits and no walks with 14 strikeouts over 6 1/3 innings. The ace isn't typically known as a strikeout pitcher, but this is amazingly the second time this season that he has punched out 14 in a game, with the first also being against the Angels on June 8. A few bad starts have inflated the 27-year-old's ERA to 4.46 on the season, but he figures to once again be one of the more reliable pitchers in fantasy for 2026.

Seattle Mariners right-hander George Kirby tossed a gem in a 1-0 win over the Pittsburgh Pirates on Sunday. Kirby threw 6 1/3 scoreless innings while allowing four hits, walking none, and striking out nine batters to earn the win. The veteran hurler led the game with 19 swinging strikes while improving his record to 3-4, to go along with a 4.22 ERA, 1.10 WHIP, and 50 strikeouts across 49 innings of work. Kirby struggled in his first two starts of the season upon being activated from the injured list in late May but has been excellent since, posting a 2.68 ERA over his past seven starts. He will be a solid fantasy starting option in his next start, which will come on Saturday against the Detroit Tigers.

Seattle Mariners starting pitcher George Kirby was dominant on Sunday in a 3-2 win against the Angels, striking out 14 batters over seven innings. He allowed two runs on two hits, which came on a Taylor Ward home run in the fourth inning. This start certainly put any worries to rest about Kirby taking a step back following his injury, as this was the most strikeouts he's tallied in a game in his career. The matchup against the Angels certainly helped, but it's clear that the 27-year-old is ready to step back into his role as a real-life and fantasy ace. He'll look to keep things rolling in his next start, which is set to be another good matchup against the Guardians.

Seattle Mariners right-handed pitcher George Kirby (jaw) is listed as Sunday's starter when the Mariners face the Los Angeles Angels. In his last start, Kirby was struck by a comebacker. However, the right-hander avoided a significant injury and is in line to make his next scheduled start. In his last start, Kirby logged five innings of two-run ball against the Orioles. He struck out three batters and allowed one walk and eight hits. Through 13 2/3 innings this season, Kirby has held a high 8.56 ERA with a 1.83 WHIP. Kirby dealt with right shoulder inflammation during the early part of the campaign and has struggled to find his footing early on. However, last summer, Kirby held a 3.53 ERA with an impressive 1.07 WHIP across 191 innings of work. He will be a strong play in DFS facing the Angels on Sunday.

Seattle Mariners manager Dan Wilson said Tuesday that he expects starting pitcher George Kirby (face) will be "OK" after getting hit in the face by a line drive in a 5-1 loss to the Orioles. Wilson said that Kirby was able to get his hand on the baseball before it hit his face and that the Mariners should know more on Wednesday. Fantasy managers should keep an eye out for more news as to whether the 27-year-old will take his next turn in the rotation at the Angels. He has only made three starts this season due to right shoulder inflammation, so it remains to be seen if the Mariners take extra precautions with him.

In a scary scene on Tuesday in the game between the Baltimore Orioles and Seattle Mariners at T-Mobile Park, Mariners right-hander George Kirby (face) left the game with two outs in the fifth inning after taking a 102.7 mph comebacker from Orioles infielder Ramon Urias off the side of his face. The ball actually ricocheted to first base for the final out of the inning, but Kirby was bleeding from his mouth and was pulled. The good news is that the 27-year-old was able to walk off the field under his own power, but he'll undoubtedly undergo testing to see if he has a concussion or any other serious injuries. Before leaving, Kirby had allowed two earned runs on eight hits while walking one and fanning three in five innings. At the very least, Kirby will be in danger of missing his next start after getting a late start to the 2025 season with another injury. He could also land on the injured. Stay tuned.

Seattle Mariners right-hander George Kirby struggled in a 9-2 loss to the Houston Astros on Thursday. Kirby allowed five runs on six hits over 3 2/3 innings of work while striking out four and walking one. The veteran hurler was making his season debut after missing the first two months of the season with right shoulder inflammation, so his less-than-stellar start can be forgiven. When he's on, Kirby has been a very good fantasy starter and should return to those standards once he gets a few more starts under his belt. Fantasy gamers shouldn't hit the panic button just yet.
