They're already planning for life after baseball.Like 90 percent of the planet, Dante Bichette Jr. - (Son of Rockie and former Yank 1st round pick) - and Mason Williams - (Not the guy who recorded "Classic Gas," but the kid viewed by many as the best prospect in the Yank system) - have formed a musical band of merrymakers and uploaded a couple songs to a free music website.Their band is called Navy58. If he were alive, Lester Bangs could sum this up in 60 words. For my money, it's stock-issue suburban strip mall rap with an R&B back beat courtesy of Garage Band. (I assume you weren't expecting Patty Page.) Hey, they're not bad. But Justin Timberlake can sleep tonight. Listen for yourself.
