As the 2025 fantasy baseball season progresses, savvy players are on the lookout for pitchers showing surprising starts. Jake Irvin of the Washington Nationals has recently made waves, posting a dominant performance against the Mets with a 1.31 ERA in his last three starts. However, despite his curveball success, his reliance on weaker fastballs raises concerns about sustainability.

Meanwhile, Simeon Woods Richardson of the Minnesota Twins has also shown improvement, limiting the Angels to just one run in a recent outing. His increased curveball usage looks promising, yet a lack of whiffs suggests he may not be a reliable fantasy asset. Lastly, veteran Jose Quintana of the Milwaukee Brewers has been impressive with a 1.14 ERA, though his sinker-heavy approach and inability to generate strikeouts could limit his fantasy appeal.
