CHICAGO -- Carlos Pena had a potential game-winning home run overturned by instant replay in the eighth inning on Sunday.
The Cubs trailed, 3-1, when Darwin Barney reached base and made it safely to third on a fielding error by right fielder Brian Bogusevic, who missed catching Barney's line drive. Starlin Castro walked, and Barney scored on pinch-hitter Aramis Ramirez's sacrifice fly, which Bogusevic grabbed as he collided with the ivy-covered brick wall.
One out later, Pena launched a ball to left that appeared to bounce off the yellow cord rimming the basket of the bleachers. Pena had hesitated at second, but third-base umpire Marty Foster signaled home run. Astros manager Brad Mills challenged the call, and after the umpires reviewed the play, Pena was sent back to second base and Castro to third.
The Wrigley Field ground rules state that if a ball hits the top of the basket in front of the bleacher wall and bounces back onto the playing field, the ball is in play.
Cubs manager Mike Quade argued that Castro held up when he saw Foster signal home run instead of running full tilt and trying to score on Pena's hit. Quade was then ejected by Foster. It's the seventh time Quade's been tossed, which ties the single-season record for Cubs managers, shared by Johnny Evers (1913) and Frankie Frisch (1950). It's also the most ejections by a Major League manager this year. Minnesota's Ron Gardenhire has been tossed six times.
Marlon Byrd then flew out to right to end the inning.
