Adrian Gonzalez has been working out with former boxer Chris Byrd, and Luis Cruz has joined him. It's yet to be seen if Cruz is packing more muscle, but at least he's aware of not packing on fat. From "Dodger Adrian Gonzalez's fitness regimen gives him fighting chance" by Dylan Hernandez at the LA Times:
"We're not dieting, but we're careful with what we eat," Cruz says. "Nothing bad. That's helped. When you're in Mexico, you eat everything. You go out and eat tacos. I had to get out of there. I would have looked like Mo Vaughn."
Interesting Vaughn is the first fat ballplayer that came to Cruz's mind. Or maybe he was just being tactful.
