Left-handed relievers lead a charmed big league existence. They work fewer innings than right-handers, they’re coveted every season at the trading deadline, and they earn multiyear deals worth millions of dollars to get a couple of outs a few times a week, even if their past results don’t justify such rewards (see Schoeneweis, Scott). Not only that, but they have more job security than any other group of major leaguers for, due to their scarcity, lefties can hang around a big-league bullpen almost as long as they see fit — Jesse Orosco, the ultimate situational lefty, pitched until he was 46.
