CHICAGO — Catcher John Baker scored the winning run in the bottom of the 16th inning after pitching a scoreless top half, and the Chicago Cubs overcame a three-run deficit to beat the Colorado Rockies 4-3 on Tuesday night.
Baker scored on Starlin Castro's fly to end game that lasted 6 hours, 27 minute, a record for longest game by time for both teams.
Chicago used seven relievers before Baker (1-0) became the first Cubs position player to take the mound since Aug. 27, 2012, when Joe Mather faced Milwaukee.
The Rockies also used all seven relievers in their bullpen, then turned to Tyler Matzek, a starter in the 16th.
Matzek (2-5) walked Baker to lead off the inning. Baker advanced to second on a sacrifice, then third on Anthony Rizzo's bloop single before scoring.
Chicago's Emilio Bonifacio had game-tying two-run homer in the fourth inning and a double among four hits. He is 14 for 35 since returning from the disabled list (strained right oblique) on July 22.
Rockies first baseman Justin Morneau returned from the disabled list and drove in two runs with a double. Corey Dickerson added two hits and an RBI
Morneau, who had been out since July 13 with a strained neck, entered hitting .312, third best in the National League. He leads Colorado with 62 RBIs.
Cubs starter Edwin Jackson lasted through just four innings, laboring with 105 pitches, and allowing three runs on six hits and three walks.
Rockies ace Jorge De La Rosa pitched six innings, allowing three runs and striking out seven. The left-hander entered with wins in five straight decisions dating to June 24.
Both teams had chances to win in the 10th.
Colorado's D.J. LeMahieu missed on a suicide squeeze with Morneau on third and Charlie Culberson on second. Morneau was tagged out by catcher Welington Castillo.
In the bottom of the inning, Castillo lined a drive deep to center field with one out and Castro on second. But the Rockies' Charlie Blackmon raced back and made a spectacular diving catch.
Rockies: In addition to Morneau, the Rockies activated left-handed reliever Logan Boone from the DL (diverticulitis/intestinal inflammation). Logan pitched a scoreless ninth. The Rockies also recalled infielder Cristhian Adames from Triple-A Colorado Springs before the game because infielder Josh Rutledge has an upper-respiratory infection.
Cubs: The Cubs placed right-handed reliever Neil Ramirez on the 15-day disabled list with a sore triceps.
