DETROIT -- The daily roster shuffle on the Tigers' pitching staff continues. To make room for starter Buck Farmer on the 25-man roster, Detroit optioned right-hander Kevin Whelan to Triple-A Toledo on Wednesday, two days after purchasing his contract.
Whelan gave up back-to-back home runs in his 1 1/3 innings of work in Pittsburgh. It was his first Major League appearance since 2011, and his first outing for the Tigers, the team that drafted him in 2005.
Since Whelan still had a Minor League option, the 30-year-old remains on the 40-man roster, and would be eligible to return by the end of August. Detroit opened a 40-man roster spot for Farmer by designating Double-A Erie catcher Ramon Cabrera for assignment.
The Pirates claimed Cabrera on waivers, bringing him back to his original organization. Cabrera, who hit .277 at Erie this season with five homers and 47 RBIs, spent five seasons in the Pirates farm system before going to Detroit in the Andy Oliver trade in 2012.
