In Week 4 of the 2025 fantasy baseball season, savvy managers are on the lookout for starting pitchers to enhance their rosters. This week features a mix of promising young arms and proven veterans. Mitch Keller of the Pittsburgh Pirates is recommended for his steady performance despite some inconsistency. Hayden Wesneski, recently traded to the Houston Astros, is showcasing potential with a strong strikeout rate, making him a must-add. Veterans Luis Severino and David Peterson provide reliable options for back-end rotation slots. For deeper leagues, Erick Fedde and Andrew Abbott are emerging as noteworthy picks, each showing solid statistical signs of potential breakout performances.

Francisco Lindor delivered a dramatic walk-off home run, his 250th, propelling the Mets to a thrilling 5-4 victory over the St. Louis Cardinals. The game was a rollercoaster, with the score tied multiple times before Lindor's heroics in the ninth inning sealed the win, giving the Mets a 2-0 lead in the four-game series.

Mark Vientos contributed significantly with a home run of his own and pivotal plays that kept the momentum alive for New York. The Mets rallied from an early deficit, showcasing their resilience, particularly during a series of tense moments that included a controversial baserunning call involving Luisangel Acuña.

The New York Mets struggled at the plate again, managing only one run in a 3-1 loss to the Oakland Athletics at Sutter Health Park. Despite generating some base traffic, the Mets only managed a sixth-inning home run from Brandon Nimmo, who cut Oakland's lead to 2-1. David Peterson pitched well, going six innings and allowing two earned runs, but he received little run support from the offense. The game marked the Mets' third loss in April, leaving them at 9-5 overall. J.T. Ginn's impressive sinker stymied the Mets’ lineup, leading to a disappointing end to their second game against the A's, who are finding their footing in Sacramento.

Under cool conditions at Citi Field, Pete Alonso continued his impressive start to the season, going 2-for-3 with an RBI to lead the Mets to a 2-1 victory over the Toronto Blue Jays. This win marked the Mets' first series sweep of the year and extended their current winning streak to four games. Alonso's performance was pivotal, as he drove in his 11th run of the season with a third-inning single.

Despite losing starter David Peterson due to health concerns, the Mets' bullpen excelled, with Max Kranick securing the win and Edwin Diaz earning the save. The Mets showed resilience, especially as their top hitters, including Brandon Nimmo and Juan Soto, stepped up, while the middle and lower order struggled. This balance will be crucial as they look to build on this momentum.

The New York Mets bounced back in the 2025 season, leveling their record to 2-2 with a commanding 10-4 victory over the Miami Marlins. The win was fueled by a powerful performance from David Peterson, who dominated from the mound, striking out nine batters over six innings while allowing just two runs. His fastball was especially effective, reminiscent of his strong 2024 campaign where he posted a 2.90 ERA.

Offensively, the Mets displayed their power, with Pete Alonso hitting a pivotal grand slam in the fifth inning, marking his first home run of the season. The slugger is now on track to break the Mets' all-time home run record, needing just 26 more to reach the top. Alongside Alonso, Starling Marte, Brandon Nimmo, and Luis Torrens also contributed to the home run tally, showcasing the team's offensive depth. Torrens has emerged as a standout player, batting .364 with two RBIs, stepping up in the absence of Francisco Alvarez due to injury.
