Rapid Reaction: Mets 4, Cubs 3

NEW YORK -- The Chicago Cubs were three outs from a sweep.

Then Carlos Marmol entered.

Marmol gave up four runs in the ninth and the Cubs fell 4-3 to the New York Mets on Sunday at Citi Field. The Cubs led 3-0 entering the frame.

How it happened: Marmol gave up two homers, a walk and a single. The only out he recorded came on a sacrifice bunt. Marmol yielded a walk-off three-run homer to Kirk Nieuwenhuis. The other homer was a solo shot by Marlon Byrd.

What it means: Instead of winning four straight and sweeping the Mets, the Cubs instead suffered a heartbreaking loss. Matt Garza pitched excellent, giving up no runs over seven innings, but Marmol couldn't hold up his end.

Outside the box: The Mets surely are going to be in SportsCenter's "Not Top 10" this week after making three errant throws in a span of about 15 seconds. With the Cubs ahead 1-0 in the fifth with two men on and two outs, Alfonso Soriano hit a sharp grounder to third and Mets third baseman David Wright dived to his left to snag the ball.His throw to first went high and wide of the base, and Starlin Castro headed home as Daniel Murphy retrieved the ball. Murphy made a quick turn and throw toward the plate, only for his throw to go wide as Castro scored. Nate Schierholtz then headed home while Omar Quintanilla recovered the ball, and Schierholtz scored easily as Quintanilla threw wide of catcher John Buck. Soriano ended up at third. The Mets were credited with two errors.

Up next: The Cubs will try to rebound against St. Louis as they begin a four-game series at Busch Stadium on Monday. Travis Wood (5-5, 2.65 ERA) faces Shelby Miller (7-4, 2.21) at 6:05 p.m. CT.
