SEATTLE (AP) Mariners right-hander Adrian Sampson needs surgery on his injured right elbow and is expected to miss the remainder of the season.
Sampson was scratched from his scheduled start in Detroit on Thursday while tossing his warmup pitches before the bottom of the first inning. Sampson felt sudden discomfort in his elbow and had to be pulled from the game before throwing a single pitch.
Sampson said he had felt good during his pregame bullpen session, but he tired late in the warmup and began to feel like he couldn't finish his pitches. When he took the mound before the first inning in Detroit, his arm was sore and aching all of a sudden.
