Starlin Castro saved his best for last two nights in a row.
One day after sinking the Cincinnati Reds with an RBI single in the ninth inning, Castro delivered a walk-off hit in the 11th to score Chris Coghlan on Sunday, securing the Chicago Cubs a 2-1 victory and series-clinching win.
It was Castro's third walk-off hit of the year and league-leading eighth such victory for the Cubs, who have now won six of their last eight to move a season-high seven games above .500.
Castro finished the game 3-for-5, while Reds outfielder Billy Hamilton collected a career-high five steals in a losing cause.
