It makes sense... he's not going to demand a starting position. He's proven offensively. Defensively, he's proven but not in a good way. However, given Garner's history of late inning defensive switches, I can't imagine his defense posing a significant problem. Between White (when he isn't starting), Lamb, and Palmeiro you have an outstanding bench of PHs in many different situations. Sounds like a good idea.
What happens to Burke if this goes down? Does he share the utility role with Bruntlett? I really hope they don't consider running Burke out to CF to make Willy available in a trade.for pitching.
