He wasn't a big name, though former MLB lefty Brad Halsey died last week due to a recreational climbing accident. I remember watching him pitch against the Jays in 2004 and he was one of the pieces the Yankees traded to Arizona for Randy Johnson. 33 is a young age - sad news to hear.
RIP
edit: was actually at that game on October 3rd, 2004 (http://scores.espn.go.com/mlb/recap?gameId=241003114). Was a big Josh Towers fan and it was the last day of the season. Also, that's the day John Cerutti died.
