Week 7 of fantasy baseball has arrived, prompting a closer look at emerging hitters in the minors worthy of stashing on your roster. Highlighting the list are Roman Anthony of the Boston Red Sox, whose path to the majors seems clearer with Triston Casas out for the season. Anthony's impressive stats at Triple-A, featuring a 147 WRC+, showcase his potential as a future star in Boston's lineup.

Another promising prospect, Matt Shaw from the Chicago Cubs, boasts impressive plate discipline metrics despite a slow start, making him a candidate for a major league return. Jac Caglianone of the Kansas City Royals is making waves with his power, currently hitting .330 with a 1.012 OPS at Double-A, while Jordan Lawlar from the Arizona Diamondbacks continues to dominate at Triple-A, boasting six home runs and 12 steals. Finally, Marcelo Mayer adds depth to the Red Sox's anticipated future, showing solid power numbers in Triple-A. These players could be key assets as the season progresses.

The Boston Red Sox find themselves at a crossroads with their top prospect, Marcelo Mayer. Currently at Triple-A Worcester, Mayer is making waves with a .273 batting average and an impressive .833 OPS, showcasing his potential as a future star. However, the presence of Trevor Story, who has four years remaining on his hefty contract, complicates things for Mayer's ascent to the major league roster.

Trevor Story remains optimistic, stating it’s beneficial for the team to have too many good players, while acknowledging Mayer's talent. Despite a lackluster .252 batting average this season, Story's veteran presence could serve as an asset during a critical phase for the Red Sox's offensive lineup. Manager Alex Cora might explore ways to integrate Mayer, potentially rotating him at second base or in the outfield to expedite his development without sidelining Story, whose experience could be pivotal for a team seeking postseason success.

The Boston Red Sox are showcasing notable depth within their middle infield positions, led by starting shortstop Trevor Story. Marcelo Mayer, the organization’s No. 3 prospect, is poised for a potential MLB debut, although he may remain at Triple-A Worcester due to the competition. Alongside Mayer, Brian Abraham, the senior director of player development, mentioned the prospects of Roman Anthony entering the fold at some point, but without a set timeline.

Versatile player Kristian Campbell has been primarily deployed at second base, indicating Boston's strategy to maximize talent on the field. The team may consider trading from their prospect pool, particularly Franklin Arias, whose impressive start at Single-A Salem could entice teams in need of infielders as the trade deadline approaches. His promotion to High-A Greenville could further enhance his trade value as the Red Sox evaluate their needs at mid-season while keeping an eye on their growing roster of shortstop talent.

The Boston Red Sox face a pressing dilemma as their top prospects, Roman Anthony and Marcelo Mayer, inch closer to their MLB debuts. The potential for their arrival raises questions about the future of current starters, particularly first baseman Triston Casas. Despite showing promise, Casas is struggling significantly this season with a .185 average and a .594 OPS, which has left manager Alex Cora questioning his long-term viability as a starter. Recent reports suggest Casas could become a trade candidate if his performance does not improve.

Casas, who finished third in AL Rookie of the Year voting last season, has shown flashes of improvement, notably hitting two home runs in a recent series against the Seattle Mariners. However, inconsistency at the plate, coupled with a below-average fielding performance, places him under scrutiny. The Red Sox's dilemma is compounded by the fact that neither Anthony nor Mayer plays first base, leaving a gap in succession planning should they decide to deal Casas. Frustrations among fans are rising, yet some argue it may be premature to give up on the 25-year-old.

As the 2025 Minor League Baseball season progresses, several prospects are stepping up, making them potential waiver wire targets for savvy fantasy managers. Marcelo Mayer of the Boston Red Sox is hitting .280 with 7 home runs and 34 RBIs in Triple-A, showcasing his power and defensive skills. Meanwhile, Jacob Misiorowski of the Milwaukee Brewers continues to shine as a pitcher, boasting a 1.82 ERA with an impressive strikeout rate, making him one to watch for an MLB debut soon.

Francisco Acuña, formerly of the Pirates and now with the San Diego Padres, is also making a name for himself with 5 home runs and a .293 average in Double-A, showing great promise after a strong week. Hunter Barco, another key pitcher for the Pirates, has yet to allow a run this season in Double-A, demonstrating his elite strikeout ability. Lastly, Leo De Vries of the Padres is turning heads with his cycle performance in High-A, indicating his potential as a five-tool player.
