Impressive for fourth win
PSeattle Mariners
September 9, 2024
Thornton (4-3) got the win against the Cardinals on Sunday, firing two scoreless innings during which he allowed a hit and recorded two strikeouts.
ANALYSIS
Thornton played a pivotal role in the Mariners' pitching plans Sunday, providing two nearly perfect innings following an earlier-than-expected call from the bullpen due to Luis Castillo's exit as a result of a hamstring strain. Thornton threw 28 pitches over his two frames and produced his 10th scoreless appearance in his last 11 outings, lowering his ERA under 4.00 (3.99) in the process. Thornton's versatility has been leveraged frequently this season, as he's logged a career-high 64 appearances that have helped him to a career-best nine holds and his most wins since he was primarily a starter for the Blue Jays in his rookie 2019 campaign.

Past Fantasy Outlooks
2021
2020
Thornton was feared to have required Tommy John surgery, but he only needed surgery to remove loose bodies in his right elbow at the beginning of September. As a result, he should be ready for the start of the 2021 campaign. The right-hander battled elbow issues over most of the season in 2020, and he only made three starts as a result. Thornton's production was skewed by a limited sample, but he still improved to a 2.66 FIP, although his 5.22 SIERA left something to be desired. He showed promise during his rookie season in 2019, but it's not yet clear how he'll perform after surgery. Thornton has a five-pitch arsenal, but he has a middling 92.2 mph average fastball velocity, and his strikeout rate hasn't jumped off the page. The 27-year-old demonstrated some effectiveness over his first two years in the majors, but he hasn't done enough to warrant a roster spot in most fantasy leagues to begin 2021.
Thornton unexpectedly emerged as Toronto's most reliable starter in his rookie campaign, tying for the team lead with six wins while pacing the squad in starts (29), innings (154.1) and strikeouts (149). Although his 4.59 FIP was far from spectacular, he finished the season on a positive note, registering a 2.19 ERA over 24.2 innings in September. Thornton doesn't throw exceptionally hard and registered a modest 22.0 K% last season, but he ranks as one of the baseball's top pitchers at generating a high spin rate, particularly on his slider and curveball. The right-hander probably won't evolve into a true staff ace, but he could grow into a solid middle-of-the-rotation pitcher if he can improve his walk rate (8.9%) and do a better job of limiting home runs (1.4 HR/9). Thornton is likely to open 2020 in Toronto's starting rotation, but he hasn't yet earned a roster spot in most fantasy leagues.

Latest Fantasy Rumors
Favorite for starting role
PToronto Blue Jays
February 23, 2020
Thornton is the favorite to be named the fifth starter in the Blue Jays' rotation to begin the season, Scott Mitchell of TSN.ca reports.
ANALYSIS
Thornton surprisingly emerged to pitch the most innings for the big-league team in 2019. However, the club added a number of arms this offseason and also has multiple prospects who are close to major-league ready. That said, even if Thornton manages to earn a starting role out of camp, he'll need to perform well to maintain it.
