Joel Hanrahan didn't exactly suffer a setback, but it appears the Tigers' newly signed reliever was asked to take a step back earlier this week.

Hanrahan was recently shut down from his second bullpen session and has resumed a long toss program, Tigers head athletic trainer Kevin Rand said Friday.

"We decided to have him throw long toss because I think he needs to build up his arm strength before we put him back on the mound," Rand said.

Hanrahan is expected to throw long toss for a week and will then be re-evaluated. If all keeps progressing normally, he could hold a bullpen session next week.

"We shut down the second session because he was having issues in trying to finish pitches," Rand said. "He just doesn't have enough arm strength yet."

Hanrahan, who has been sidelined since last May after tearing a flexor tendon that required Tommy John surgery, signed a one-year deal with the Tigers in early May. He was placed him on the 15-day disabled list and has rehabbed in Lakeland.
