The Tampa Bay Rays have reinstated reliever Jesse Crain from the 60-day disabled list.

Tampa Bay acquired the injured Crain from the Chicago White Sox on July 29.

The Toronto-born right-hander had gone 2-3 with a 0.74 earned-run average in 38 appearances before being placed on the DL on July 3 because of a right shoulder strain.

Prior to the trade, Crain averaged 11.3 strikeouts per nine innings.

At 86-69, Tampa Bay entered play Monday with a half-game lead over Cleveland (86-70) for the first wild-card spot in the American League.

Crain’s return is a huge boost to the Rays bullpen. Earlier this season, he was named an all-star for the first time in his 10-year major league career.

Crain was told he probably would be pitching by the end of August.

“I would have liked to have been in the last 2 ½ months,” Crain, who is a free agent after the season, told reporters. “As a competitor, you want to go out there every day, especially with the number of close games we’ve been in where I know I could have stepped in and helped, but it’s a process.

“And it’s something where you have to make sure when you come back, you’re able to finish the season.”

In other Rays news, right-hander J.D. Martin was designated for assignment before Monday's game.

The Rays say the results of an MRI exam Sunday showed that centre-fielder Desmond Jennings has a mild left hamstring strain. Jennings, injured running the bases Sunday, is listed as day to day.
