Heston Kjerstad would probably look anywhere for a bit of hope right now. It turns out he doesnโt have to look far.
The struggling young sluggerโs first full season in the majors, which represents the most extended run of playing time heโs had at this level since debuting in September 2023, has been a challenging one for both Kjerstad and an organization that has waited to see what the 2020 No. 2 overall draft pick could do.
A .190 average with a .545 OPS and just eight extra-base hits in 147 plate appearances was not what anyone expected. Itโs also not unprecedented. Kjerstad has leaned recently on the advice of Ryan Mountcastle, whose own first full season in the majors started poorly, as evidence of how all is not lost.
โHeโs taken me under his wing a little bit and talked to me about how his first full season went in the big leagues and how he didnโt have the start youโd want to have and how he had to just keep showing up, working through it, and thereโs still a lot of baseball left,โ Kjerstad said. โYouโre one little, small adjustment away from being the kind of hitter you want to be in the box. Just keep having confidence, keep showing up every day with a positive attitude, keep working hard in the cage and doing everything you did.โ
That took a while to pay off for Mountcastle in 2021. After a promising debut late in 2020, he started flat the following year and had a .577 OPS and just three home runs on May 20. Not long after, Mountcastle clicked into gear. He homered four times in five games as May turned to June, had his OPS up to .752 by the All-Star break and ended the year with 33 home runs and a .796 OPS. He had a .618 OPS in his first 44 games and an .872 OPS in his next 100.
Mountcastle was happy to share his experiences with Kjerstad.

โI was like, โDude, I know it may seem like everything is just caving in, but you can get out of it.โโ Mountcastle told him, paying back advice heโd received when he was going through it.
Trey Mancini had a full season in the majors on his resume when he dealt with his first extended slump in 2018. Mancini was off to a fine start when he banged his knee on an exposed portion of the wall down the left-field line on April 20. He played on, but he didnโt hit well for that entire first half.
He hit .194 with a .617 OPS in the next 71 games but reset at the All-Star break to rally for a .792 OPS in the second half, leaving him at .715 for the year.
โTrey was always such an awesome dude,โ Mountcastle said. โI feel like me and him were sort of similar in a way, play types and stuff like that. So I could always relate to what he was saying. He had some talks with me, and he told me to keep going, the same things I was saying to Heston.โ
Kjerstad seemed encouraged when he heard how Mountcastle ended that season, with a club rookie record for home runs (33). Mountcastle thinks that type of production is on tap for Kjerstad once things steady for him.
โIโve seen him hit in game, seen him hit in BP,โ Mountcastle said. โHeโs a 30-home run guy. Once he gets going, itโs going to be fun to watch.โ

Thatโs something Kjerstad feels is going to be a product of his timing. He feels heโs been in between a lot this year, meaning heโs rolling over pitches heโs early on or late on.
โI havenโt been consistent on either of those,โ he said. โNow there are a lot of factors that can go into that, when Iโm getting my leg kick off or what my approach is. Itโs just dialing that in and, once I have my timing, that seems to be once I start really rolling.โ
Those two relatively unusual aspects of Kjerstadโs offensive game โ his leg kick and his approach โ need to be working for him to be who heโs meant to be. He never particularly excelled at the swing-decision aspect of the Oriolesโ development philosophies in the minors but made up for it with his ability to understand how he was being pitched and hit mistakes in certain areas of the plate.
Kjerstadโs 2024 season was a disjointed one due to inconsistent playing time and then a July concussion that cut short a productive spell. He had a 1.141 OPS in 14 games leading up to Clay Holmes hitting him in the head with a fastball, but his swing map was heavily concentrated last year around the top of the strike zone and above it โ pitches Kjerstad can drive in the air.

This year, his swings arenโt concentrated anywhere. There are zones where he swings often all over the strike zone, and some areas at the bottom or below it where heโs swinging much more often. While none of Kjerstadโs overall rate stats in the plate discipline area is meaningfully different, the types of pitches heโs swinging at seem to be, and thatโs influencing the quality of contact heโs making.
At this stage of his career, Kjerstad is the type of players whose power production will justify the approach rather than his approach yielding the power production. At present, the slug isnโt there โ and thereโs not a lot in his underlying or expected stats to suggest itโs due, save for maybe some bad luck on fastballs heโs been driving.
But, discouraging as the results may be, Kjerstad can only follow Mountcastleโs advice and try to power through it all.
โThe main thing from him was keep having fun, enjoy every day, and good day or bad day, keep working on what you believe in and eventually itโll show through and youโll start hitting the ball like you want to,โ Kjerstad said.
