My Phillies' Question of the Day

My question of the day relates to the famous (infamous?) "countdown to 10,000 losses" here in the City of Brotherly Loss, I mean, Love...

Who is the losing-est Phillie of all time?

I figure there must be some poor shlub who got stuck playing for the Phils in the 30's for like 10 years and was subsequently a part of the most losses ever in Phillies' history for one player. Trivia buffs and statisticians, help me out!
