The 2025 fantasy baseball season is heating up, and savvy managers are scanning the waiver wire for breakout pitchers. Matthew Liberatore of the St. Louis Cardinals, Grant Holmes of the Atlanta Braves, and Gunnar Hoglund of the Oakland Athletics are three intriguing names rising to the occasion.

Liberatore is showing promise with a solid 3.07 ERA and a drastic reduction in his walk rate, now in the 94th percentile. His four-seam fastball has transformed into a reliable putaway pitch, leading to a significant uptick in strikeouts. With only 39% of leagues rostering him, he's a prime candidate for fantasy adds.

Holmes, on the other hand, has posted a 4.24 ERA and a high walk rate, putting him at risk for negative regression. Despite occasional flashes of brilliance, the volatility in his performance makes him a more cautious add at 41% rostered.

Finally, Hoglund has made a splash with an impressive 2.38 ERA in his limited innings. Despite this, he has a small sample size, and fantasy managers should keep an eye on his development in the majors. He's currently at 34% ownership, making him a potential streaming option in favorable matchups.
