Here is Aaron Gleeman's take on the Rondell White-Bubba Trammell trade. Like most observers, Gleeman thinks that the addition of Mark Phillips makes the deal a sound one for the Bombers:
I really like Mark Phillips. He's a big left-handed starter with awesome stuff. Baseball America ranked him as the #3 prospect in the San Diego system and I would agree with that ranking.
Phillips was San Diego's #1 pick (ninth overall) in the 2000 draft. He runs his fastball up there in the mid-90s and also works with a great curveball that one of my readers who has seen him pitch quite a bit once described to me as "disgustingly filthy," which is about the highest compliment you can give a pitcher.
The caveat for all pitching prospects is that they need to stay healthy (which Phillips has done) and show they can pitch at the upper-levels of the minors (which Phillips has not done). Still, as far as pitchers that haven't pitched at Double-A yet go, I like Phillips quite a bit.
He struck out 9.5 batters per 9 innings last year at Single-A. His control was pretty bad at times (5.7 BB/9), but I don't worry about that as much in a 21 year old pitcher. Mark Phillips is still a long way from the Major Leagues and may never get there, but he is potentially a #1 or #2 starter at the Major League level and has awesome stuff and good results in the minors so far.
Basically the Padres sold him and an extra season of Bubba Trammell to the Yankees for $5 million dollars. I'm just not sure I would have been willing to do the same.
