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.

As Week 12 of the 2025 fantasy baseball season unfolds, key players are rising or falling in performance, impacting their value in fantasy leagues. Evan Carter of the Texas Rangers has shown promise with a .283 batting average, powered by speed and newfound power since his call-up. In contrast, Corey Seager is struggling, battling performance issues and injuries, presenting a potential buy-low opportunity for fantasy managers.

Jeff McNeil from the New York Mets is trending upward with a solid .268 average and improved power metrics, while hitters like Brice Turang, who initially excelled, are now underperforming in stolen bases. On the pitching side, Shelby Miller has stepped up as a closer for the Arizona Diamondbacks, while David Peterson of the New York Mets is having a breakout season. However, Bailey Ober's inconsistencies raise concerns for fantasy owners.

As fantasy baseball heats up, Week 12's waiver wire adds feature an exciting mix of emerging talent and steady veterans who can elevate your lineup. Among the top picks are Josh Smith from the Texas Rangers, who has turned his season around with an impressive June, boasting a .378 batting average and showcasing his multi-position eligibility. Jeff McNeil of the New York Mets, quietly having a strong season, has also turned heads with a .333 average over his last 14 games.

Jo Adell from the Los Angeles Angels has found his groove, slashing .346/.424/.788 with seven home runs in a recent hot streak. Evan Carter, also from Texas, is making a strong return, hitting .283 with significant power and speed. Ryan McMahon of the Colorado Rockies is rediscovering his form after a slow start, while Cade Horton from the Chicago Cubs continues to impress on the mound. Finally, Shelby Miller of the Arizona Diamondbacks is stepping into the closer role and should be picked up if saves are needed. These players all present significant upside as we approach the halfway mark of the season.

On June 12, 2025, the MLB landscape is brimming with potential for home run bets, especially given the favorable hitting weather across the East Coast. Star players like Juan Soto and Jeff McNeil of the New York Mets are primed for big performances against pitcher Michael Soroka, who has struggled against left-handed hitters this season. Both players are on hot streaks, with Soto recently achieving a .707 SLG and McNeil hitting a .711 SLG over the last 14 days.

Additionally, Heliot Ramos of the San Francisco Giants is in a good spot at Coors Field facing Antonio Senzatela, who has been vulnerable to right-handed batters. Capping off the spotlight is Vinnie Pasquantino from the Kansas City Royals, who is putting up impressive offensive numbers against a struggling Will Warren. With the right strategies, bettors can capitalize on these matchups.

As we progress into June, the fantasy baseball landscape is evolving. The waiver wire is thinning, but there are still valuable players to consider adding to your roster. Key among them is Ronny Mauricio, whose recent call-up to the New York Mets has shown both promise and volatility. He’s currently rostered in just 16% of Yahoo leagues, making him a potential boom or bust candidate.

Another intriguing option is Ben Brown from the Chicago Cubs. After a rocky start, his recent performances suggest he's finding his groove, especially with a notable reduction in walks and an impressive strikeout rate. Lastly, Jeff McNeil, a consistent performer with the Mets, is also worth investigating as he continues to demonstrate an upturn in form since returning from injury.
