Lamet (elbow) will begin a minor-league rehab assignment with High-A Lake Elsinore on Wednesday.
Lamet has been pitching in extended spring training games for most of May, working up to three innings multiple times. The right-hander has been sidelined since undergoing Tommy John surgery in April of 2018, so he figures to require a handful of rehab starts before being cleared to rejoin the big-league rotation. The Padres are hoping to have Lamet back by the end of June.
