The first month of the season may be in the books, but there are still plenty of valuable fantasy commodities available on the waiver wire. There have been plenty of surprises already, both good and bad, but that’s baseball, as they say.

The law of averages will likely even things out as the season progresses, so don’t panic just yet. But if you are in need or one of your regulars is hurt, these next few studs are those you should be targeting. There should be something for everyone, so let’s get right to it.

Fantasy Baseball Waiver Wire Targets (2025)

All players listed are rostered in 55% or fewer of Yahoo leagues. Also, I rarely repeat a player week to week, so it’s not a bad idea to check back to prior articles to see if any of those players are still available. That said, here are the top nine waiver wire pickups for Week 4 of the 2025 fantasy baseball season.

Sal Frelick (OF – MIL): 26%

Sal Frelick won’t hit more than a handful of home runs, but he will contribute in batting average and stolen bases. Frelick is an excellent slap-hitter who uses the entire field to his advantage and rarely strikes out.

Through 20 games, he’s up to a .319 average with five stolen bases and 11 runs scored. He also bats fifth or sixth in the lineup, which should now give him an ample amount of RBI chances. His speed and average alone make Frelick a solid addition for the weeks ahead.

Jose Soriano (SP – LAA): 46%

Jose Soriano has already served up a couple of clunkers this year, but one was due to a single bad inning, and the other was some really bad luck. The good news is that Soriano is on tap for a two-start week against two of the weaker offenses in the league.

The 27-year-old is set to kick off Tuesday’s games with a matchup against the Pirates. He’s then scheduled to face the Twins. Both teams rank near the bottom in runs scored per game, averaging right around 3.5.

Soriano has been a ground-ball specialist this year, averaging an impressive 61.4% ground ball rate. He also strikes out a decent number of hitters and has had two stellar outings, contrasting the two bad ones. Soriano also performed well overall in his sophomore campaign. With two softer opponents coming up, Soriano and his 100-mile-per-hour (MPH) stinker are worth adding in most leagues.

Andrew Abbott (SP – CIN): 18%

Andrew Abbott has been extremely lucky in his first two outings, registering an outlandish .105 batting average on balls in play (BABIP) and a 100% left-on-base rate. Those numbers will change, but there’s no denying what he’s done so far. In the two games since returning from the injured list (IL), Abbott has surrendered just two runs on four hits while striking out 16.

Abbott was decent in his first two years in the league, maintaining an ERA below 4.00 while striking out a fair number of hitters. His weakness is the volume of home runs he gives up. Playing in Cincinnati won’t do him any favors, but while he’s striking out 40% of the hitters he’s facing, Abbott is worth a look.

Brandon Young (SP – BAL): 2%

Injuries continue to mount in Baltimore, as Zach Eflin is the latest starting pitcher to join the injured list. Down to just a few healthy arms, the O’s are calling on Brandon Young for Saturday’s start.

Young is a nice prospect with some decent upside, but he does come with some risk. He doesn’t throw very hard, nor post the gaudy strikeout totals you like to see from highly touted prospects. But he does throw some plus-plus secondary pitches and was the Orioles’ top Minor League pitcher last year.

He’s done well in two Triple-A games so far this season. If Young does well this weekend, he’ll likely stick around. Young is worth stashing for now, especially if he goes off this weekend.

Lance McCullers (SP – HOU): 5%

A blast from the past. Dare I mention Lance McCullers? He is still only 32 years old (if you can believe it). Despite dealing with multiple arm injuries, the sweeper specialist is finally on the brink of return.

McCullers has looked good in his rehab starts, striking out nearly 35% of batters over his last two outings. I don’t see the veteran pitching out of the bullpen. While he’s a long shot to pitch deep enough into games to make a real fantasy impact, he still possesses value in deeper leagues.

Dylan Moore (1B, 2B, SS, 3B, OF – SEA): 45%

We’ve seen this movie before from Mr. Moore. The Mariners’ utility man gets hot for a few weeks, just to let everyone down the following period. While I do believe there is still plenty of risk in starting Dylan Moore, there’s no denying his numbers over the first month.

Moore is not only stealing as expected (he’s up five on the season), but he has cut down significantly on his strikeouts and has produced an OPS above 1.000. It’s still very early, but with Moore’s speed and his early ability to put the bat on the ball more often, he could be an excellent value going forward.

Shane Smith (SP, RP – CWS): 14%

The top overall pick in this winter’s Rule 5 Draft has been nothing short of spectacular this year. Milwaukee must be kicking themselves for not protecting the 6-foot-3 righty after seeing what he’s doing in Chicago. Over three starts, the recently turned 25-year-old has produced a 2.04 ERA with a 51% ground ball rate and zero home runs allowed. He’s also maintained a 0.91 WHIP.

Smith was fantastic in Milwaukee’s system over the last two years, but he worked more as a swing-guy than an actual starter. As a full-time part of a Major League rotation, Smith is showing just how valuable he truly is. Hopefully, he doesn’t make me eat my words this Saturday, but so far he’s been excellent.

Jonathan Aranda (1B, 2B – TB): 49%

Out of the entire MLB, do you know which three hitters rank at the top of OPS? Aaron Judge, Pete Alonso and, you guessed it, Jonathan Aranda (1.144). Aranda has been putting on a clinic for Tampa, amassing 21 hits over the first 18 games. Eleven of those have gone for extra bases, including three home runs.

The Rays first baseman has collected 11 RBI and 11 runs as well. History says Aranda won’t end up more than a mediocre commodity, but while the 26-year-old is punishing baseballs, he’s worth a look in all league types.

Tyler Fitzgerald (2B, SS, OF – SF): 43%

Tyler Fitzgerald is the first player I’m repeating this season. Before Opening Day, I highlighted him as someone who could be an excellent sleeper going late in drafts. But after he was regularly batting in the nine-hole, I felt like he lost some value and wasn’t producing enough.

Now that he’s back to hitting, stealing bases and mashing the power, Fitzgerald has been moved up in the lineup. Now in a more productive position, he’s playing like the five-tool category stud that he is.

Fitzgerald has posted a .310 batting average to go along with four steals, two home runs, 10 runs scored and six RBI. The Giants shortstop put up similar numbers last year as he finished half a season with 15 homers, 17 steals and a .280 batting average. He also qualifies at multiple positions and has been clocked at over 30 feet per second, ranking his sprint speed in the top 1% of the league.

Fitzgerald likely won’t move up to the top half of the lineup unless a few players get hurt, but he’s worth a waiver wire bid while giving you a bit of everything.
