What is the situation with Diablo Bats and MLB? I was of the understanding they were no longer approved by MLB for game bat use. Is this for maple bats only? Ash as well? Reason I ask is that in last night's (Fri 5-15) game, Prince Fielder used a D-bat in his first AB. Given the game was canceled after a couple innings, I couldn't find any photos to check specifics of the bat, but just curious if anybody knew the D-bat situation.
