12. Dec. 22, 2009: Yankees Acquire Javier Vazquez, Again, for Melky Cabrera/Mike Dunn/Arodys Vizcaino
Fool me once, shame on me. Fool me twice? Well, sh--shame on ... I won't get fooled again!
Five years after dropping him off in Arizona in the Randy Johnson trade after an up-and-down 2004 season that ended in the dumps (we'll get to that later), the Yankees tried to reinforce their repeat chances by sending Melky Cabrera to Atlanta (and opening up a starting role for Brett Gardner) in exchange for Javier Vazquez.
Somehow, it went far worse the second time. Vazquez was eminently hittable in 2010, posting a 5.32 ERA in 157.1 innings and finding himself out of the rotation by crunch time. Naturally, he rebounded with a 3.69 ERA the next season in Florida, his final big-league campaign.
Turns out, the Yankees also acquiring Boone Logan in this deal ended up being the way more impactful move! Probably not good.
