I really don’t see the point. The Braves, basically, traded Macay McBride for an older pitcher with a worse track record who is having a worse season.
Ledezma, a Venezuelan, was signed by the Red Sox in 1998 at the putative age of 17. He pitched pretty well in rookie ball but had a tough time of it in low-A the next season and evidently was hurt, as he missed all of 2001. He pitched decently in 2002 in A-ball but the Red Sox didn’t protect him from the Rule 5 draft.
The Tigers, under their top-secret “Break the AL record for losses” plan, drafted Ledezma. He worked mostly out of the bullpen, though he had eight starts, and did his part in the Tigers’ run for history. Ledezma bounced between AAA and the majors, and between starting and relieving, over the next few seasons, not doing anything spectacularly well but not washing out. In 2006, he had a strong year, mostly in the bullpen, putting up a 3.58 ERA, but has not pitched well in 2007. Word was that the Tigers were going to put him on waivers.
Ledezma throws hard but hasn’t quite harnessed that to become a big strikeout pitcher, and has control issues. The one thing that McBride does well is Ledezma’s greatest weakness. McBride, in his 85 2/3 inning major league career, has allowed three homers. Ledezma has allowed four this season. If you’re going to use a guy as a situational reliever, a tendency to allow homers is the last thing you want. He hasn’t pitched well against lefthanders this year, but that’s unusual for him.
