Who is Jason Bay?

Well your new left-fielder, of course.

He's a tick above a league-average left-fielder. A career .280 hitter, with an OPS+ of 130. He had a down-year last year but has been having a nice bounce back so far this season. He's hit twenty-two home runs, with fifty-nine walks, and sixty-four RBI. He's got an OBP of .375 this season. He's also stolen seven bases. In 2005, he played in all 162 games for the Pirates. He's kind of useless against left-handed pitching (hitting only .193) but pretty good against righties (hitting .308, with a .570 SLG.)

The important stuff: In interleague play this year the Pirates went against the Yankees, the Orioles, the White Sox, Toronto, and Tampa Bay. Against the Yankees he went four for ten in three games, with a pair of singles off Joba and Moose, and a pair of doubles off Rasner and Hawkins. Against the Orioles he went five for eleven with a single and a double off Burres, a single of Chad Bradford, a double and a single off Cabrera. Against Toronto he went two for eleven, he didn't fair well against Halladay but did hit a home run off Jesse Litsch and a single off Dustin McGowan. Against Tampa Bay he went three for thirteen with a double off Kazmir, a walk-off home run off Jason Hammel, and a sacrifice fly and a double off Andy Sonnastine. He played in two of the games against Chicago, he went two for eight with a double and a single.
