Six hot fantasy baseball waiver wire pickups, streamers, and sleepers for Week 10 (2025). Undervalued hitters outperforming their ownership percentage and should be more widely owned.
Week after week during the fantasy season, bats go cold while others get hot. Players also get injured, and fantasy managers are left looking for replacements to fill the void left in their lineups.
It's early, and although the waiver wire in many leagues has been picked clean, with the ebbs and flows of the season, there are still bats on the waiver wire worth rostering, even if it is for a short time.
As we head into Week 10 of the fantasy baseball season, several underowned hitters offer sneaky value on the waiver wire and have picked it up at the plate recently. Some players offer big-time power potential like Jesus Sanchez, players that can get you a stolen base like Caleb Durbin, and others who can do a little of everything like Ernie Clement. We'll discuss those players and some others below.

Addison Barger, 3B/OF - Toronto Blue Jays
36% rostered
The Blue Jays called up Addison Barger in mid-April, and it took him some time to get going. He hit .171 (7-for-41) with three doubles and zero home runs over the first 16 games of 2025.
Since a three-double game on May 9, however, the left-handed slugger is hitting .325 (27-for-83) with eight doubles and six home runs in 23 games, currently riding an impressive four-game home run streak. (Update: Barger went 0-for-4 on Wednesday, ending his HR streak)
With contact, chase, walk, and strikeout rates right around league average, there doesn't seem to be any indications of big regression in the works (other than not hitting a home run in every single game from here on out, of course).
On the contrary, a hard-hit rate of 55.2 percent, a barrel rate of 14.6 percent, a 99th percentile average exit velocity, and an xBA of .305 compared to his actual BA of .274 point to more of an ability to keep up the production.
The former sixth-round draft pick is a zero in the stolen base department, but with the ability to hit for a decent average and on pace for 25 home runs, the 25-year-old is still lightly owned at 36 percent rostership.
With the added flexibility of being eligible at both 3B and OF on Yahoo!, Barger is worthy of at least a bench spot in most 12-team leagues.
Ernie Clement, 2B/3B/SS - Toronto Blue Jays
18% rostered
Before an 0-for-3 on Tuesday, Ernie Clement was riding a six-game hit streak, during which time he went 13-for-26 (.500). Six of those 13 hits went for extra bases, too, including four doubles and two home runs.

Like Barger, Clement got off to a slow start, hitting .186 (8-for-43) through his first 19 games. Also, like Barger, a three-hit game got him out of his funk. Since a 3-for-5 day on April 19, Clement is hitting .308 (41-for-133) over 39 games with nine doubles and three home runs.
Unlike Barger, Clement does not post high barrel or hard-hit rates. However, he does provide an above-average contact rate of 85.1 percent and a 90th-percentile strikeout rate of 13.0 percent, so he should continue to put the bat on the ball.
Both Barger and Clement's counting stats should benefit from the saying that "a rising tide lifts all boats," as Toronto's offense has picked up steam lately. Over the last two weeks, the team has scored the fifth-most runs and recorded the fifth-most RBIs. The team's wOBA and wRC+ were second-best behind only the Cubs.
The 29-year-old is eligible at 2B, 3B, and SS on Yahoo!, and is only 18 percent rostered. The positional flexibility allows Toronto to keep his hot bat in the lineup most days, and it will do the same for fantasy managers whose regular starters might be getting a day of rest.
Mike Tauchman, OF - Chicago White Sox
6% rostered
Mike Tauchman had missed most of the season with a hamstring strain before returning from the IL on May 23. The veteran has logged 10 starts since then, and reached base in nine contests via hit or walk, going 13-for-39 (.333) with four doubles, a triple, two home runs, and an 8:8 BB:K.
(Update: Tauchman went 1-for-3 on Wednesday with an RBI double and a walk)

The 34-year-old's two seasons with the most games played came in the last two years as a member of the Cubs, playing in 108 games in 2023 and 109 games in 2024.
He doesn't typically hit for much power, but has been able to reduce his strikeout rate in each season since 2021, while posting slightly above-average contact rates and maintaining a double-digit walk rate every year since he debuted back in 2017.
The left-handed hitter's offensive environment may limit his counting stats somewhat, but for managers in a pinch who are looking to stream a hot outfield bat, Tauchman is just six percent rostered.
Jesus Sanchez, OF - Miami Marlins
9% rostered
Jesus Sanchez looked somewhat like a deep sleeper after ending 2024 with a .305 batting average in September, along with six steals during the month, finishing the year with a career high 18 homers and 16 stolen bases.
An oblique injury in mid-March caused the 6-foot-4 slugger to miss the first couple of weeks of the season, finally returning to action on April 15. Then, as has been the case with most of these guys, it took a while to get going, hitting .196 (10-for-51) over his first 15 games.
In the 26 games since, he's hitting .316 (30-for-95), which includes three of his four home runs on the season and five of his six steals. It also includes the nine-game hit streak that the 27-year-old is currently riding, too.
(Update: Sanchez came on as a pinch-hitter Wednesday and went 0-for-1, ending his hit streak)
Players with a leadoff HR and a walkoff triple in the same game in the modern era (since 1901):

The left-handed batter doesn't hit lefties well, so he does not get much play against them, evidenced by his .182 (4-for-22) BA against LHP, so he could be somewhat frustrating in season-long fantasy leagues if the Marlins were to see a string of lefties.
But he can be a very solid DFS play in favorable matchups, slashing .290/.373/.419 against RHP this season, and has hit them much better throughout his career. The Marlins will face three straight righties this weekend against the Rays, so the Dominican would be in play.
Carlos Santana, 1B, Cleveland Guardians
19% rostered
Carlos Santana broke into the league in 2010, and at age 39, he doesn't show signs of slowing down. The switch-hitter has recorded a better-than-average strikeout rate in every single season, which has been paired with a double-digit walk rate.
The same holds true in 2025, posting a 17.1 percent K% and a 13.6 percent BB% through 55 games. A .344 wOBA and 124 wRC+ show he's still plenty productive, and he's even backed it up with a current 12-game hit streak, during which time he's gone 18-for-42 (.429) with three doubles, three home runs, eight RBI, and 11 runs scored.
(Update: Santana went 1-for-4 on Wednesday, extending his hit streak to 13 games)
Carlos Santana (5) - Cleveland Guardians
360 feet pic.twitter.com/9rqPDxdarp— MLB Home Run Clips (@HRClipsMLB) May 21, 2025
The former All-Star hit 23 home runs in the last two seasons, and while he may not get there this year, he's still on pace for around 18 long balls. Paired with a decent average and hitting in the heart of the Guardians' lineup, there should also be plenty of RBI opportunities.
Fantasy managers in AL-only leagues should consider picking up the veteran, and those in other leagues could stream him while he's hot.
Caleb Durbin, 2B/3B/SS - Milwaukee Brewers
5% rostered
With an 88.9 percent contact rate and minuscule 7.7 percent strikeout rate in 42 games played, it was somewhat surprising to see Durbin mired in a 4-for-45 (.089) to begin May.
Since May 19, a stretch of 14 games, the 25-year-old is 15-for-51 (.294), which is an obvious improvement, but it hasn't all been singles. The diminutive infielder has seven doubles during that time.

He's also logged a 4:5 BB:K and been hit by two pitches, recording a .362 OBP, and when he gets on base, he can steal bases. Four of his five steals have come in the last couple of weeks. Durbin swiped 31 bags last season in the minors, but also ran wild in the 2023 and 2024 Arizona Fall League (50 SB in 47 G), as well as during this year's spring training (10 SB in 18 G).
If he can continue to hit, he'll continue to steal bases. Managers in NL-only leagues and those desperate for steals in 12-team and deeper leagues could try to catch lightning in a bottle with Durbin.
