In the quest for reliable starting pitching in fantasy baseball, three breakout pitchers have caught attention early in the 2025 season: Landen Roupp, Andrew Heaney, and Mitchell Parker. Roupp, of the San Francisco Giants, has showcased tremendous strikeout potential, posting a 31.2% strikeout rate over his first four starts. His impressive 2.98 SIERA suggests that his current 4.09 ERA could improve significantly.

Meanwhile, Andrew Heaney, now with the Pittsburgh Pirates, has achieved a stellar 1.72 ERA and a 3.08 SIERA, indicating that he's found a new level after a tumultuous career. Lastly, Mitchell Parker of the Washington Nationals has surprised many with a low 1.39 ERA, although his underlying metrics suggest he may regress soon, making him a risky but intriguing prospect for fantasy teams. Each of these pitchers presents unique attributes that could bolster a fantasy rotation during this critical point in the season.
