Evan Longoria's rehab assignment was suspended indefinitely after the Tampa Bay Rays third baseman experienced discomfort in his partially torn left hamstring.
Longoria grounded out in the first inning of his second rehab game for Triple-A Durham, then left the game. It wasn't a re-injury, but Longoria didn't want to push it.
He will rejoin Rays on Tuesday in Washington and continue to rehab there.
There's no timetable for his return, or for when he would resume his minor league assignment.
Longoria had gone 1-for-4 Saturday in his first rehab game for Durham. He has been on the disabled list since May 1 with the hamstring injury, and he had been hoping to return to the Rays soon.
In All-Star voting announced Monday, Longoria remains third among American League third basemen. He hit .329 with a .433 on-base percentage, a .561 slugging percentage, four homers and 19 RBI in 23 games for Tampa Bay before he got hurt.
