I speculated on who would be sent down once Nomar Garciaparra was activated earlier today. And the winner (well, loser) is... Ramon Troncoso.
He was one of the few guys I mentioned, and his 9.53 ERA was most likely the deciding factor in the end. It's certainly not the end of the line for him, as he's only 25. He pitched scoreless ball in his first 4 appearances covering 3.2 innings, but was roughed up for 6 runs in his last 2 innings.
It's not like Triple-A Las Vegas is the best place to improve your numbers pitching, but with the Dodgers crazy injury history, if he can prove he can keep the ball down and get outs, he'll be back.
