George Klassen Fantasy Stats

Los Angeles Angels right-handed starting pitcher George Klassen will attend big-league spring training. The right-hander enters the 2026 campaign sitting as the team's No. 3-ranked prospect on MLB.com. Klassen was a sixth-round selection by the Phillies back in the 2023 MLB Draft and is now steps away from making the MLB Opening Day roster. In 2025, the Minnesota product spent most of his season at Double-A, where he logged 102 2/3 innings to the tune of a 5.33 ERA with a 1.48 WHIP. During this stint, he struck out 126 hitters while allowing 46 walks. However, over his last four outings at Double-A, he posted an elite 1.17 ERA, which earned him a one-game taste of Triple-A. If Klassen continues to perform well in camp, he could be in the mix to join the Angels early in the first half.

Los Angeles Angels right-handed pitching prospect George Klassen is a name to monitor during spring training. Klassen is currently considered the No. 3-ranked prospect in the system on MLB.com. In 2025, the right-hander spent the majority of the year in Double-A Rocket City before earning a brief six-inning stint at Triple-A Salt Lake. Across 102 2/3 innings at Double-A, the former sixth-round selection from the 2023 MLB Draft posted a hefty 5.35 with a 1.48 WHIP. However, over his last 23 innings at Double-A before earning the promotion, Klassen posted a dominant 1.17 ERA with 32 punchouts. At Triple-A, Klassen totaled eight strikeouts across this brief stint, while allowing two runs with one free pass. Given Los Angeles's weak pitching depth, Klassen could be in strong consideration for a promotion early in the season.

Los Angeles Angels pitching prospect George Klassen was promoted to Triple-A Salt Lake on Tuesday after spending the entirety of 2025 at Double-A. The Angels' third-ranked prospect posted a 5.35 ERA, 1.48 WHIP, and struck out 126 batters in 102 2/3 innings pitched (24 starts) this season, but had been better as of late, recording a 1.17 ERA, 1.26 WHIP, and a 21.4 percent K-BB% over his last four starts prior to the promotion. After being traded from the Phillies in August of last year, the former sixth-round draft pick registered a 16.9 percent walk rate in eight starts, but improved that to 10.0 percent in 2025, so there could be less reliever risk than there once had been. In his first start at Triple-A on Tuesday, the 23-year-old allowed two earned runs on six hits and one walk while striking out eight in six innings of work. He's worthy of consideration in dynasty leagues and could debut in the majors in 2026.

Los Angeles Angels right-handed pitching prospect George Klassen tossed six shutout frames en route to picking up the victory over Double-A Pensacola on Friday. In this outing, Klassen allowed just two hits and one walk. He struck out five. This was a nice bounce-back outing for Klassen as he allowed 14 runs (13 earned) over his last three starts (8 2/3 innings). However, prior to this slump, the No. 3-ranked prospect in the system posted a 3.86 ERA and a 1.21 WHIP over his first 25 2/3 innings of work. Through 40 1/3 total frames, Klassen has struck out 49 batters and held a modest 5.36 ERA. However, his slump in early June has inflated his ratios. Fantasy managers should continue to monitor his progression as the former sixth-round pick could earn a second-half taste of Triple-A.

Los Angeles Angels pitching prospect George Klassen tossed 5 1/3 shutout innings for Double-A Rocket City on Tuesday, allowing three hits and one walk while striking out nine batters. It marked the third consecutive dominant outing from the righty, who yielded just one earned run on 11 hits and three walks while striking out 22 over those three starts (13 1/3 innings). The 6-foot-2 hurler could pitch his way to Triple-A by season's end, but he isn't expected to make his big-league debut until sometime in 2026. Still, with a 34.9 percent strikeout rate in 26 minor-league starts, the Angels' third-ranked prospect is a player dynasty managers should be keeping tabs on.

Los Angeles Angels pitching prospect George Klassen tossed five innings of one-run ball on Wednesday against Double-A Montgomery. He allowed five hits, no walks, and tallied a season-best eight punchouts. This was a strong bounce-back outing for Klassen as he allowed five runs (zero earned) and six runs (all earned) over his first two starts of the season, respectively. Across those two outings, Klassen tallied just seven punchouts across five 2/3 innings of work. Klassen is considered the No. 3-ranked prospect in the Angels system on MLB Pipeline. Last summer, the Minnesota product split time with Low-A, High-A Jersey Shore before moving up to Double-A Rocket City. Across 93 total innings, Klassen held a solid 3.10 ERA with a 1.18 WHIP. He could be in the mix to make his Triple-A debut later this summer.

Los Angeles Angels pitching prospect George Klassen has been promoted to Double-A Rocket City. The Angels acquired Klassen from the Phillies in the Carlos Estevez trade and in his only start at Single-A for his new club this past weekend, the righty threw five innings of one-run ball, allowing three hits and three walks while striking out 10 batters. For the season, the 22-year-old sports a 1.96 ERA, a 0.99 WHIP, and 99 strikeouts in just 64 1/3 innings pitched. The former sixth-rounder is looking more and more like the real deal and although MLB.com's Top Prospects list sets his ETA at 2026, it wouldn't be a surprise if he were to make his MLB debut at some point next season.

After an impressive start to professional career this season at Single-A Clearwater, the Philadelphia Phillies have rewarded pitching prospect George Klassen with a promotion to High-A Jersey Shore. Klassen, 22, is looking like a steal as a sixth-round pick in 2023 early in his career and has pitched to a miniscule 0.71 ERA with 57 strikeouts and 12 walks in 38 innings over his first nine starts. Klassen underwent Tommy John in 2021 and missing so much time could be a reason that the Phillies were able to get him so late in the draft, but so far, the right-hander has looked like an excellent pick. Klassen has a fast delivery and can hit triple-digits on the mound. He also throws a changeup, curveball and slider. Klassen is a couple years away from a potential debut and a name for dynasty league managers to start keeping an eye on.

Philadelphia Phillies pitcher George Klassen overpowered Low-A hitters again on Thursday in Clearwater. The right-hander struck out seven batters and allowed just two hits and two walks against Dunedin. Klassen has yet to allow an earned run over 15 innings this season and has struck out 24 batters to just four walks. The former sixth-round pick appears to be ready to move up in the Minor League ranks, and with elite stuff, he could be a fast riser in the fantasy community. While it is unlikely that Klassen will make an impact in 2024, fantasy managers should get in now before he takes off at the higher levels.
