Week 12 of the 2025 MLB season sees a variety of waiver wire hitters who can significantly boost your fantasy baseball team across key categories like HR, RBI, SB, AVG, and runs. Notably, Giancarlo Stanton makes a return, adding power potential to a struggling Yankees lineup. Meanwhile, young talents such as Brady House and Max Muncy are stepping up, providing upside for fantasy managers looking to capitalize on emerging players.

Other noteworthy adds include veterans like Trevor Story and Jeff McNeil, both contributing significantly in their respective categories. With injuries and poor performances affecting many rosters, this week presents a prime opportunity to enhance your team with these players, ensuring you remain competitive in your leagues.

Heading into Week 12 of the 2025 fantasy baseball season, five notable players are under scrutiny for their performance. Tyler Mahle of the Texas Rangers had an impressive start with a 1.47 ERA but has since struggled, currently on the injured list with shoulder soreness. Despite this downturn, he should be held in most leagues due to potential recovery.

Matt Shaw from the Chicago Cubs showed promise after a Triple-A stint but has recently hit a slump, suggesting a possible drop if he doesn't regain form. Lars Nootbaar of the St. Louis Cardinals has been in a significant slump and may warrant being dropped. Kansas City Royals prospect Jac Caglianone is not producing at the MLB level yet but should be held due to his strong minor league performance and potential upside.

Lastly, Matthew Liberatore of the Cardinals has seen regression, and fantasy managers should consider trading him while there's still some value, particularly after his next start. The analysis reveals a critical juncture for these players as fantasy managers weigh their options.

The MLB weekend brings an exciting lineup for DFS players, with 11 games scheduled. Notable pitchers include MacKenzie Gore of the Washington Nationals, who is showcasing a remarkable 2.88 ERA and a 12.61 K/9 rate, making him a strong candidate against the Miami Marlins. Noah Cameron of the Kansas City Royals is also a key player to watch despite a tough last outing against the Yankees, facing the Oakland Athletics next. Colin Rea is a budget-friendly option against the Pittsburgh Pirates, who have been struggling offensively.

Among hitters, Kyle Schwarber's power remains a focal point, aiming for his 40-homer season, while Christian Yelich is rebounding with significant contributions. Stacking recommendations include the Atlanta Braves against Austin Gomber's Rockies and the Mets facing Shane Baz, with stars like Pete Alonso and Brandon Nimmo leading the charge.

The Detroit Tigers are facing challenges as they approach the MLB All-Star Game. After a recent mediocre stretch of 4-4 against weaker competition, they are adjusting their roster due to injuries. Ace Tarik Skubal continues to lead a strong pitching staff, but the team suffered a significant blow with the UCL injury of promising starter Jackson Jobe, who requires Tommy John surgery.

In response, the Tigers have reshuffled their bullpen, promoting Matt Gage from Triple-A Toledo while demoting Beau Briske. Gage, who has a solid career ERA of 1.83 in limited appearances, will fill the void left by Jobe and must step up in this crucial time for the Tigers. As they navigate this transition, the focus will be on maintaining their competitive edge in the league.

The Detroit Tigers are enjoying a remarkable resurgence in 2025, boasting their best performance since the early 2010s, driven by a roster of primarily role players who gained confidence from a surprising ALDS run last year. Tarik Skubal, the reigning Cy Young winner, has been particularly impressive, recording 16 consecutive scoreless innings, including a 'Maddux' against the Guardians. However, the Tigers are looking to bolster their bullpen as they prepare for the season's critical juncture.

ESPN's Jeff Passan has suggested that the Tigers could be interested in acquiring Bo Bichette, the two-time All-Star shortstop from the Toronto Blue Jays. With Bichette set to enter free agency, the Blue Jays might consider trading him instead of risking a loss without compensation. His power bat, highlighted by a stellar May, could provide a much-needed offensive spark, complementing the likes of Kerry Carpenter, who recently made headlines by hitting three home runs in a game, marking the first such performance for a Tigers player since 2016.
