Joe Ryan was always an intriguing pitching prospect because he has never fit the profile of a typical pitcher. His unique fastball has been discussed at length since joining the Twins organization, and that's what made him so successful in the minors. He releases the ball at a three-quarters arm angle, which can mess with how batters view the expected pitch. One of Ryan's most important focuses was developing his secondary pitches because he wouldn't reach his ceiling throwing fastballs over 60% of the time. Here's a look at his early season changes in 2023. 

Some of Ryan's early season success is tied to the high strike rate he has been able to accumulate in the season's first month. Inside Edge pointed out that he has thrown at least two strikes in his first three pitches to 78% of opposing batters this season. For reference, the league average is 65%. He has been ahead or even in the count in 111 out of 143 plate appearances this year (78%). Ryan is holding batters to a .342 SLG when he is ahead in the count with 27 strikeouts in 64 at-bats. 

One reason for Ryan's early season success has been a dramatic change in his pitch mix. During the 2022 season, he threw his fastball over 60% of the time while also relying on his slider (17.8%), changeup (12.1%), curveball (7.2%), and sweeper (2.8%). In 2023, he's using his fastball less than 60% of the time for the first time in his career, and his slider usage has dropped to 5.5%. His most significant increase in pitch usage has been a pitch that Baseball Savant categorizes as a split-finger (27.5%) and a sweeper (9.2%). 

His slider is getting hit the hardest (.625 SLG), up 85 points compared to last season. He has held batters to a .170 SLG or lower against his split-finger and sweeper. Seven of his eight extra-base hits have come against his fastball, but that is expected with how regularly he throws the pitch. Last season, his fastball was the only pitch with a negative run value for the season (-21 runs), and that total ranked among baseball's best. During the 2023 season, his fastball (-6 runs) and splitter (-5 runs) are both providing negative run value. It will be interesting to track those pitches throughout the season since he currently throws them over 85% of the time.

Ryan's improvements this year have helped him post an extreme chase rate that will be tough to maintain for an entire season. Last year, his chase rate ranked in the 33rd percentile among MLB pitchers. To begin 2023, his chase rate ranks in the 96th percentile. There is some hope that his new pitching repertoire will help him continue to get batters to chase pitches, but there will also likely be some regression to his career mark.

Unfortunately, not everything is positive for Ryan. He is giving up a lot of hard contact with a Hard Hit % that ranks in the 23rd percentile. He does a tremendous job at hitting his spots but has below-league-average velocity. Hitters can make solid contact on the occasions when his location fails to be perfect. He has given up a lot of ground balls this season, which puts extra pressure on the defense. The Twins' infield defense has ranked poorly to start the season, and he will likely see a few more ground balls find holes behind him in the coming weeks.
