MLB Buy Low/Sell High Candidates

It’s time to cash in on some overreactions and underrated players from the first month-ish of baseball. Add them to your fantasy teams and get ready to back and fade them all summer.

I’m sure not many are too locked into what Amed Rosario is doing, especially considering he is largely regarded as a platoon bat at this point in his career. And Aaron Boone loves his splits, as people frustrated with Ben Rice’s playing time know very well. So it’s still unlikely he gets some heavy increase in playing time against righties even though he deserves it. But Rosario has more ABs against RHP than LHP this year and is actually hitting better against them, at .308 compared to .211. Rosario has also made noticeable swing changes, as his bat path and speed has increased in 2026. And as he sits at just 4/19 against LHP on the year, he hasn’t reached his ceiling as a hitter this year yet. His expected numbers look great on top of him barreling up the ball and not striking out very much. I think Rosario will start to grab a lot of Yankee fans' attention here very shortly.

This is the guy that many pegged to break out this year, and the early returns haven’t been great. He continues to hit the ball hard, which will never really change with Cags. The issue is he refuses to hit the ball in the air. 105 off the bat doesn’t do very much for you when it threatens the life of the ants in front of home plate before anything. It’s not like he’s having a disaster of a year, hitting .269 with a .750 OPS. But the power hasn’t necessarily been there as much as some thought. The monkey might’ve finally gotten off his back though, hitting his first HR last night against the Orioles. Just as the rest of the Royals lineup should see improvement in more hitter-friendly conditions over the summer, I think the same applies for Cags. As he starts to get more favorable fly ball matchups (certainly in more favorable fly ball weather too), I think he can begin to lift the ball more and more throughout the season. Carter Jensen has been the young Royals hitter to show promise early on, and Jac Caglianone is next.

Feels like Bailey Ober has done the same song and dance every year. He has a stretch of a month or so where he dodges trouble and looks great with a bad outlier start stuck somewhere inbetween. Ober was on a bit of a pitch count early to manage his return from injury so hard to judge the results wholly from those first 1-2 starts but has looked solid since. He just threw his best outing of the season, going 6.1 IP of shutout baseball with 10 Ks against the Reds. His ERA is sitting just over 4 and he has yet to take a loss on the season. But he still has a lot of issues that will bite him over the course of the season. His fastball is horrid and tops out at around 90, hence the amount of barrels it catches. Which means in some starts he’ll have to rely on throwing his offspeed for strikes consistently. The command in that area is a large concern and is the exact reason why when Bailey Ober is bad, he’s REALLY bad. It’s helped him so far that 4 of his 5 starts have been at home in Minnesota, so cold weather where the ball won't carry as much when he tosses his batting practice fastball. When the weather starts warming up and he faces some patient lineups, it’ll be a real issue for him. I look forward to fading very soon.

Michael McGreevy is almost a polar opposite type of pitcher than Bailey Ober. He’s the pitch to contact guy who is more of the stereotypical “he can’t keep getting away with it” pitcher. He has put together some great starts this year, amassing a 3.29 ERA over 5 starts. Just like any pitcher on this list though, the expected numbers aren’t great and he will likely start getting knucked pretty shortly. He has had trouble with lefties in his career so far so his answer to that was to go sinker/slider to RHB and fastball/changeup to LHB. That appears like it’s working, as LHB are only hitting .194 off of McGreevy. But he hasn’t faced really any lineup with powerful lefties. His 5 starts so far have been the Rays, Marlins, Nats, Tigers, and Guards. The only real powerful lefties he has seen are James Wood and Jose Ramirez. Jose took him yard first AB and Wood’s first 2 ABs were 116 and 111 MPH singles. Even the Marlins had a bit of success nickel and diming him after the first time through the lineup yesterday. I think McGreevy begins to struggle in May, sell your stock.
