60 Danny Hultzen, SP

Mariners manager Eric Wedge said Monday starting pitcher prospect Danny Hultzen, who has been sidelined for Triple-A Tacoma since mid-April with a shoulder injury, has begun playing catch, according to the Tacoma News Tribune. But the Mariners don't plan to rush Hultzen back into action.

Although he doesn't have an exact timetable for Danny Hultzen's promotion to the majors, Mariners manager Eric Wedge sounded like he's anticipating Hultzen's arrival this season.

"Sooner rather than later," Wedge said during an interview with MLB Network Radio.

But Hultzen hasn't pitched since mid-April for Triple-A Tacoma because of a rotator cuff strain and tendinitis in his left shoulder. Hultzen, who is one of the top pitching prospects in baseball, is 3-1 with a 2.78 ERA and .198 opponents' batting average in four starts for Tacoma. He has struck out 25 in 22 2/3 innings.
