MLB Trade Deadline: Mets bolster bullpen with Ryan Helsley, Tyler Rogers; roster impact, fantasy analysis

The New York Mets have made significant moves to strengthen their bullpen ahead of the MLB trade deadline. They acquired right-handed reliever Ryan Helsley from the St. Louis Cardinals and left-handed reliever Tyler Rogers from the San Francisco Giants. Helsley, a power pitcher with a high-90s fastball, has been one of the most dominant relievers in baseball this season, posting a 1.25 ERA and 13 saves. Rogers, known for his unique submarine delivery, has been a reliable setup man for the Giants, with a 4.31 ERA and one save. These acquisitions are expected to bolster the Mets' bullpen and improve their chances of making a deep postseason run. The roster impact includes increased competition for late-inning roles, which could affect the fantasy value of the Mets' existing relievers. However, the additions of Helsley and Rogers are seen as positive moves that should strengthen the team's overall pitching depth and performance.
