MacKenzie Gore was always supposed to be a star but pitching prospects are extremely fickle. Factor in injuries and his development hasn't gone exactly as planned. Not that he hasn't been useful but if you said before 2020 that going into 2025 Gore's career stats would read 21-26 with a 4.20 ERA, 4.14 FIP and 1.422 WHIP you'd be disappointed. Those are the numbers of a #3 type starter, not an ace.
At the major league level, and really at all levels since 2020, his problem has been two-fold. Too hittable and too many walks. So while his homer rate has generally been ok and his strikeout rate generally good, guys would get on and guys would get around. His innings would be long and he just couldn't last long into games. He was just another pitcher.
This year so far we've seen a different Gore. His control is much better. He's getting ahead of batters (first pitch strike percentage is way up, getting more called strikes, and throwing in the zone more. This is giving him control of the at bats and keeping his walks down but strikeouts high. He appears to be leaning more into his curve ball, arguably his best pitch taking a bit off his fastball and a lot off his slider to make it match his change up more in speed. This is something he did in 2023 but got away from in 2024. The difference from 2023 though is he was a fastball pitcher who used a slider and curve to mix things up. Last year he really bumped up the change and now he's a four pitch pitcher, where the slider and change hit about the same speed keeping hitters more off-balance.
Pitching can be about learning what works and doesn't. And what works in the minors isn't necessarily what works in the majors. He could throw that speedball by them and then use a hammer curve and later the solid slider to finish hitters off in high school and low minors. But major league hitters weren't as easily beat. His fastball doesn't quite pop enough to rely on it to beat a hitter (see Ohtani last night) and his slider could be flat at times (see Ohtani last night). Since the curve could be fairly easily identified hitters could lay off that and handle Gore even with in general pretty good stuff. Locate the fastball though, lean more into a hard to hit curveball, make the slider able to be confused with a tumbling change-up, well you start to see what happens.
I'm not sure this is something that will last. It hasn't been perfect as his start in Toronto was full of hits. And we've seen pitchers run through a couple good starts. Hell, we've seen them run through a couple good months. But if you could spell out what you wanted to see from Gore early this is it. Honestly looking forward now to his next start to see if we can get more confirmation that he'pitching different and that it makes a difference.
