Welcome to Waiver Wire Watch, our weekly fantasy baseball waiver wire guide. We'll be doing things a little differently this season, with Eric Samulski publishing the initial waiver-wire article on Friday afternoon. Then James Schiano updates it every Sunday to make sure you get the most up-to-date information.The premise of the article is pretty straightforward.

We'll give you some recommended adds each week based on recent production or role changes. When we list a player, we'll list the category where we think he’ll be helpful or the quick reason he’s listed. We hope it helps you determine if the player fits what your team needs.

Not every "trending" player will be a good addition for your specific roster.To qualify for this list, a player needs to be UNDER 40% rostered in Yahoo! formats. We understand you may say, “These players aren’t available in my league,” and we can’t help you there. These players are available in over 60% of leagues and some in 98% of leagues, so they’re available in many places, and that can hopefully satisfy readers who play in all league types.⚾️ Baseball is back on NBC: MLB returns to NBC and Peacock in 2026!

Matthew Pouliot,Fantasy Baseball Waiver Wire HittersJeremiah Jackson - 2B/3B/OF, BAL (52% rostered)(FULL-TIME JOB, POTENTIAL LATE BREAKOUT)With Jackson Holliday and Jordan Westburg hurt and Coby Mayo struggling, Jackson has emerged into a full-time role in Baltimore and could hold onto it even when Holliday is back from his wrist injury.

On the season, Jackson is hitting .321/.328/.571 with four home runs and 14 RBI. He has yet to steal a base this season, but he stole 11 in 85 minor league games last year and has multiple 20-stolen-base seasons in the minors, so there is double-digit speed upside here if Baltimore ever decides to run. Jackson is not going to walk, and he is going to swing and miss, but he has started swinging more often, which gives him more chances to make meaningful contact.

He's also pulling the ball more this season, which has led to an early 11.6% barrel rate. This is more about an approach change than anything. Jackson isn't going to knock the cover off the ball, and he's not going to take a walk, so the Orioles have gotten his bat speed up slightly and have him being more aggressive and looking to get the ball out front more often.

That has led him to maximize his contact more often. If he keeps his starting role, there is a world where he is a 15/10 guy with a .250-.260 average while hitting in the middle of a strong lineup. Given his multi-position eligibility, that's a valuable piece on your roster.Sunday update: Jackson's roster rate ballooned from 38% on Friday morning to 52% by Sunday likely due to this huge home run he hit on Friday night.Jeremiah Jackson Earl Weaver special for the lead!

The O's put up SIX RUNS in the 8th! pic.twitter.com/o5F1s2rlmI— Baltimore Orioles (@Orioles) April 18, 2026It capped of a six-run eighth inning that the Orioles entered trailing 4-0. In his last six games entering play on Sunday, he has four home runs and 11 RBI. Also, Jackson Holliday had a slight setback on his rehab stint while he recovers from a broken hamate bone this spring, giving Jackson even more runway as Baltimore's starting second baseman.

Regardless, he is way too hot for them to even consider taking him out of the lineup.Angel Martínez - 2B/OF, CLE (38% rostered)(FULL-TIME JOB, SPEED, POWER POTENTIAL?)Entering this season, Martínez had a paltry 77 wRC+ over the 182 games he'd played in his career and didn't seem like much of a hitter despite decent contact rates. Suddenly, he's discovered much more power. Seven of the eight hardest hit balls of his career have all come in the 20 games he's played so far.

Also, his bat speed is up over two miles per hour from the right-side. The Guardians have rewarded that growing power by hitting him either second or first against every left-handed pitcher they've faced. Most of his plate appearances will still come from the left-side though and it's still a bit of a waiting game to see if he can maintain consistency there.

Especially given his free-swinging nature. Regardless, right now he's playing every day, is eligible at the very weak second base, stealing bases, and finding some power relative to his expectations. A 15 homer, 20 stolen base season with a passable batting average is well within reach.Xander Bogaerts - SS, SD (36% rostered)(EVERY DAY JOB, COUNTING STAT UPSIDE, POWER BOOST?Look, Bogey gets forgotten about because he's 33 and people treat him like he's boring, but he's doing some interes
