The good news for Boesch was that it was the first time he was able to swing a bat in quite a while. But that doesn't mean that he'll be able to endure it in a game.
The Tigers and Boesch are trying the splint after talking earlier this week with Royals outfielder Jeff Francoeur, who wore the same thing after tearing a ligament in his thumb late in the 2009 season. He wore it down the stretch and the next spring after undergoing offseason surgery to repair the ligament.
Whether the splint works for Boesch, who has a different swing than Francoeur, remains to be seen. Boesch tore a ligament in his thumb three weeks ago in Cleveland.
