Curveballs for Jobu

Curveballs for Jobu is Offbasepercentage's daily trip around the ballparks.

Today's honorary bat boy is Chuck Carr.

Cubs 3, Cardinals 2. Some crazy person wandered onto the mound at Busch Stadium and got to pitch for Chicago. No one said anything until the sixth inning, when Cubs' manager Lou Piniella came and took the ball and the crazy person left the field. Rumors were swirling that the loony then went into a pet shop and declared himself "finally eligible for one of the upper level kitten cages."

Mariners 9, Indians 3. Josh Bard hit a grand slam on his daughter's fourth birthday, but unfortunately she's not expected to have another birthday until sometime in August, 2011, also the expected date of Seattle's next win.

Rays 7, Orioles 3. Bucky Good Times was rolling along again Saturday, up 3-0 on the AL Wild Card leaders. Then, apparently, Kelly Shoppach happened. Shoppach hit a go-ahead grand slam in the fourth and added a solo home run later in the game to lift Tampa.

Diamondbacks 9, Nationals 2. The series of the year just gets better and better. Saturday, Miguel Montero popped two home runs and Ian Kennedy allowed two runs in seven innings. Meanwhile, the Arizona bullpen threw two scoreless innings in the same game for the first time since 2002.

Twins 2, Athletics 0. Steve Tolleson: 1-for-3, single.
