Guerra consistently hit 98-99 mph during Cactus League play, Kevin Acee of The San Diego Union-Tribune reports.
The right-handed reliever isn't guaranteed a spot on the Padres' Opening Day roster, though he finished spring training on a positive note by pitching four straight scoreless outings and frequently approaching triple-digit velocity. However, Guerra has been plagued by injuries in recent seasons, and he has thrown only 50 frames across both the majors and minors since 2019. One thing working in his favor as he seeks a spot on the 28-man Opening Day roster is that he is out of minor-league options.
