The end of the fantasy baseball season is fast approaching. Whether they’re a seasoned veteran flying under the radar or an exciting new prospect, one or more of the following six players can give your team a boost this week in fantasy baseball:
Jakob Marsee
(OF, Miami)
67% Rostered
Ranked as the Marlins’ 10th overall prospect by MLB Pipeline, Jakob Marsee has exceeded expectations in every way this season. He debuted on August 1st against the Yankees and leads all of baseball in fWAR since then.
Managers in both points leagues and rotisserie leagues should be excited about Marsee. In 85 big-league plate appearances, the outfielder has a .345 xBA (per Baseball Savant) and .624 xSLG. In addition to his incredible quality-of-contact metrics, the Miami outfielder has shown off plate discipline that belies his age.
After his 92 walks ranked fifth in the minor leagues last season, Marsee has drawn free passes at a 12.7% clip this year. That puts him in the 92nd percentile among players with at least 75 plate appearances this season. His chase rate ranks in the 94th percentile among said players, meaning he’s likely to continue drawing walks even as his overall offensive production regresses.
Miguel Andujar
(3B/OF, Cincinnati)
52% Rostered
Miguel Andujar is an MLB veteran of nine seasons, but 2025 has arguably been his best since 2018. While his offensive profile could be more well-rounded, Andujar batting .310 in 271 at-bats this season due to an 86th-percentile whiff rate and 89th-percentile strikeout rate.
Despite having slightly improved since last year, Andujar’s quality-of-contact metrics are still mediocre at best. His xBA and xSLG sit at .263 and .393, respectively, as a result. But even as a .263 hitter, Andujar can provide value, especially in points leagues. Among players with at least 250 plate appearances this season, a .263 batting average would be good for the 67th percentile.
Tommy Pham
(OF, Pittsburgh)
17% Rostered
Like Andujar, Tommy Pham has been around the league for a long time. Unlike Andujar, he is rostered in less than one-fifth of fantasy baseball leagues. That makes now a great time to strike for fantasy managers looking for an everyday player with low chase rates and high exit velocities.
Pham and Juan Soto are the only two qualified players (2.1 PA per team game, according to Baseball Savant) with a chase rate ranking in at least the 95th percentile and an average exit velocity ranking in at least the 85th percentile. Pham’s ability to be selective and hit the ball hard this season is a large reason he boasted the 11th-highest OPS in baseball (1.043) during July.
This season, Pham is batting .267 and getting on base at a .341 clip. Both are well above league average, which is a welcome sight for fantasy managers in deep points leagues.
Lenyn Sosa
(1B/2B/3B, Chicago White Sox)
62% Rostered
It’s been another disappointing season for the White Sox, but the same can’t be said for Chicago infielder Lenyn Sosa. Because of his bat-to-ball skills, Sosa gets away with a high chase rate.
His tendency to swing at pitches outside the strike zone has led to a minuscule walk rate, which is the only real knock on Sosa’s production this season. The infielder is one of only 10 qualified hitters to rank in the 50th percentile or higher in all the following statistics: xwOBA, xBA, xSLG, Barrel%, Exit Velocity, Hard-Hit%, Whiff%, Bat Speed, and Squared-Up%.
The other nine hitters include the likes of Juan Soto, Ketel Marte, Yandy Diaz, Vladimir Guerrero Jr., and Ben Rice. Managers in points leagues will get above-average fantasy production from Sosa, and adding him will boost home run and batting average scores for many fantasy managers in rotisserie leagues. Sosa ranks 5th among primary second basemen in home runs (17) and 8th in batting average.
Zebby Matthews
(SP, Minnesota)
67% Rostered
By no means is the back of 25-year-old right-hander Zebby Matthews’ baseball card impressive. The Minnesota starting pitcher has a 5.30 ERA in 11 starts this season, and his 1.52 WHIP certainly isn’t a sight for sore eyes.
However, Matthews has some characteristics that should intrigue fantasy managers. Among starting pitchers who can match his innings total (19.1), Matthews has the 14th-highest Stuff+ rating (a pitch quality metric hosted at Fangraphs) this month.
Matthews’ best pitch is a slider that opponents are hitting just .165 against this season. There are only three other starters (min. 200 sliders) whose sliders match or exceed the hard-hit rate and batting average of Matthews’: Chris Sale, Freddy Peralta, and Hunter Greene. All three have been very successful starting pitchers for fantasy baseball managers in the past, and Matthews has the stuff to join them.
In addition to his wipeout slider, Matthews also features a four-seam fastball that averages 96.4 MPH. Perhaps it’s no surprise that he owns a strikeout rate north of 28% this season, which ranks in the 87th percentile among qualified starters.
Carson Williams
(SS, Tampa Bay)
56% Rostered
Carson Williams is MLB Pipeline’s 47th-ranked overall prospect and the Rays’ top prospect. He made his big-league debut on Saturday night, launching a long home run for his second career hit.
Williams is only rostered in 56% of Fantrax leagues, but he represents one of the biggest chances for fantasy baseball managers in the late-season prospect callup wave. As his aforementioned MLB Pipeline scouting report discusses, his ceiling is extremely high:
“He’s been a power-speed threat ever since and was named the top prospect in the Southern League in 2024 after slashing .256/.352/.469 with 20 homers and 33 steals in 115 games for Double-A Montgomery. What’s more, he is strong for his size at 6-foot-2 and utilizes that with a simple setup and violent swing that gets the ball in the air. A better understanding of swinging at more drivable pitches will keep that strikeout trend moving in the right direction and allow Williams’ plus power to play even more.”
Williams’ power-speed ability makes him one to watch (especially in dynasty rotisserie leagues) during the home stretch of the 2025 fantasy baseball season.
