The Tigers made the Cody Ross for Steve Colyer deal for a simple reason today–they want to avoid a repeat of 2003 in Detroit. ‘We like Ross,’ said Steve Boros, a special assistant to GM Dave Dombrowski, ‘but we need to win some in Detroit, and to do that, we needed another lefthander in the bullpen.’ The Tigers sent down Eric Eckenstahler from big league camp and intend to keep lefties such as Rob Henkel, Will Ledezma and Nate Robertson in starting roles. Robertson threw well enough in a big league game Thursday that he may have won the fifth-starter’s job in Detroit, while Henkel and Ledezma will join righties Kenny Baugh, who has touched 91 mph with his fastball this spring, and Preston Larrison in the Double-A Erie rotation. Righthander Kyle Sleeth, the organization’s first-round pick in 2003, will join them later in the year after starting in the warm weather at Class A Lakeland.
