Just over one month into the MLB season, we have a sample size large enough for our first xwFIP leaderboard of the year!
Here are the top pitchers in baseball with at least 8 innings pitched (IP).
Table 1: Top 30 pitchers by xwFIP through 4/30/25 with at least 8 IP
Picking up from where he left off last season, A’s closer Mason Miller has the best xwFIP in baseball at 0.70. He’s followed by Angels righty Ryan Zeferjahn, Blue Jays closer Jeff Hoffman, Dodgers reliever Kirby Yates, and Guardians reliever Hunter Gaddis in the top 5. The Yankees have three relievers (Fernando Cruz, Tim Hill, and Mark Leiter Jr.) in the top 30 and the Phillies have two relievers (Jose Alvarado and Matt Strahm) and one starter (Zack Wheeler).
The table below lists the top 30 starters in baseball with at least 4 starts:
