Whitley activated off DL, optioned to Double-A

Cobb throws four innings in rehab start for Triple-A Durham

Whitley activated off DL, optioned to Double-A

ST. PETERSBURG -- Rays pitcher Chase Whitley completed his rehabilitation from Tommy John surgery on Tuesday night. He was activated off the disabled list and optioned to Double-A Montgomery.

Whitley's 30-day rehab window finished after he threw six scoreless innings for Class A Advanced Charlotte on Tuesday. The reason for optioning him, Tampa Bay manager Kevin Cash said, was so he could get innings that might not be available to him at the Major League level.

Cash said it's definitely possible that Whitley will be with the Rays in September, when rosters expand to 40 players.

Whitley had a 0.86 ERA in 21 rehab innings. He hasn't pitched in the Majors since May 2015, after undergoing surgery to repair a torn UCL. He makes his home near Montgomery, Ala.

"He's part of our big picture and part of our plans moving forward," Cash said. "Without a doubt."

• Rays starter Alex Cobb threw four innings in his rehab start for Triple-A Durham on Tuesday and allowed one run. Cash said all the reports on Cobb were positive.

The right-hander will be back in St. Petersburg by Thursday to throw a bullpen session before going back out on his rehab assignment. Cobb is also recovering from Tommy John surgery, and he hasn't pitched in the big leagues since 2014.
