As the 2025 MLB season approaches the halfway mark, identifying key fantasy baseball contributors from the waiver wire is crucial. This week, players like Willi Castro and Javier Baez are racking up runs, with Castro hitting .319 and Baez contributing significantly in various positions. For power hitters, Ryan McMahon is proving his worth with six home runs this month, while Jo Adell continues to show promise with 16 homers this season. On the bases, Spencer Steer and Victor Scott II offer speed, and Ernie Clement is delivering a strong average with .380.

The fantasy landscape is evolving, with players like Casey Schmitt and Brooks Lee also emerging as valuable assets. As managers look to boost their lineups, these under-the-radar options could provide the necessary edge in the competitive fantasy landscape.

Week 13 of the MLB season brings a host of outfield waiver wire options for fantasy baseball enthusiasts. Notable picks include Lars Nootbaar and Alec Burleson of the St. Louis Cardinals, both thriving during a seven-game week. Nootbaar showcases a strong hard-hit rate, while Burleson's recent performance includes multiple home runs and a high batting average. Jeff McNeil of the New York Mets and Victor Scott, also from the Cardinals, provide versatility and speed, respectively. In the deeper leagues, keep an eye on Jake Mangum of the Tampa Bay Rays and Luke Raley from the Seattle Mariners, both of whom offer potential upside as they re-enter their teams' lineups.

Assessing the matchups this week, teams like the Braves and Cubs are set for extended play, making their players prime streaming candidates. With six teams scheduled for seven games, maximizing plate appearances is crucial for fantasy success. Players like Matt Wallner of the Minnesota Twins and Harrison Bader present power-speed combinations, essential for fantasy rosters. As the season progresses, monitoring these emerging talents could provide significant boosts to your fantasy squad.

Jacob Misiorowski, a promising prospect for the Milwaukee Brewers, made a stunning MLB debut, taking a no-hitter into the sixth inning against the St. Louis Cardinals. His performance included five innings pitched, no hits allowed, three walks, and five strikeouts. Misiorowski's outing was cut short due to calf and quad cramping, highlighting the team's cautious approach given his potential as a cornerstone for the franchise.

Despite the injury, Misiorowski's electric stuff was on display, with 14 pitches exceeding 100 mph and a variety of sliders and changeups clocking above 90 mph. The Brewers had a comfortable 6-0 lead when he exited, showcasing their strong offensive support. Misiorowski has been touted as one of the top prospects in baseball, and while control issues have been a concern in the minors, his strikeout rate suggests he has the potential to translate that success to the big leagues.

Week 11 of the 2025 MLB season brings exciting waiver wire opportunities for fantasy baseball enthusiasts, especially among outfielders. With the Chicago Cubs, Milwaukee Brewers, Pittsburgh Pirates, and St. Louis Cardinals playing seven games each, maximizing plate appearances is essential. This week's picks feature a mix of one-week streamers and potential long-term roster additions.

Addison Barger of the Toronto Blue Jays is highlighted for his impressive performance, posting a .299 average with 6 home runs and 17 RBIs since May. Roman Anthony from the Boston Red Sox shows promise as a top prospect, likely to make his MLB debut soon. St. Louis Cardinals' Victor Scott II stands out for his speed, having stolen 17 bases, while Parker Meadows of the Detroit Tigers offers a blend of power and speed returning from injury. Sal Frelick from the Brewers is also a strong contender with consistent hitting.

This week’s fantasy baseball pickups are led by Matt Shaw of the Chicago Cubs, who has been stellar since his return. He boasts multiple position eligibility and has demonstrated significant power and speed potential, making him a must-add for managers. Chase Meidroth of the Chicago White Sox is another strong option, hitting consistently and batting leadoff, while Victor Scott II, a potential steals leader for the St. Louis Cardinals, continues to go largely unclaimed. Jordan Beck from the Colorado Rockies has also emerged as a key player, showing impressive power numbers.

For pitching, Will Warren of the New York Yankees has been exceptional in recent outings, striking out a high number of batters, while Jack Leiter of the Texas Rangers is a promising stream option against struggling teams. Finally, while Daniel Palencia of the Cubs is less reliable, he’s still worth a flier for save opportunities. With playoffs approaching, these additions could make a difference for your fantasy team.
