CHICAGO – Drew Stubbs hit a tiebreaking RBI single in the 11th inning Wednesday night, and Cincinnati beat the Cubs, 6-5, hours after Reds manager Dusty Baker left the ballpark for chest X-rays.

A team spokesman said the tests were to “rule out pneumonia.” Bench coach Chris Speier brought the lineup card to home plate and there was no sign of the 63-year-old Baker during the game.

Brandon Phillips’ lazy popup with two out in the 11th on a windy night at Wrigley Field was misplayed by Cubs right fielder David DeJesus, allowing Phillips to reach second. Stubbs then smoked a run-scoring single to left against Alberto Cabrera (0-1).
