Yan Gomes hit a two-run single in the ninth inning and Michael Fulmer stepped up at the very end, helping the Chicago Cubs top the Colorado Rockies 5-4 on Monday night.
Gomes finished with three hits and three RBIs. Christopher Morel homered and Dansby Swanson had two hits for Chicago in the opener of a six-game trip.
The Cubs stayed three games back of NL Central-leading Milwaukee and two games head of Arizona for the second NL wild card.
Drew Smyly (11-9) got four outs for the win, and Fulmer earned his second save of the season in his first big league appearance since Aug. 24.
Fulmer, who had been sidelined by a forearm strain, replaced Smyly with one out in the ninth. He walked Elias Díaz and hit Elehuris Montero with a pitch before striking out Harold Castro and Brenton Doyle.
Colorado left-hander Kyle Freeland was charged with three runs and eight hits over six innings.
The Rockies scored three times in the seventh to take a 4-3 lead. Hunter Goodman doubled home Díaz and then scored on Doyle’s two-run single against José Cuas.
The Cubs rallied against Tyler Kinley (0-2) in the ninth. Swanson led off with a double off the glove of left fielder Nolan Jones and Ian Happ walked. Following a double steal, Gomes drove in both runners with a liner to center.
Pete Crow-Armstrong, one of baseball’s top prospects, made his big-league debut for Chicago. He entered as a pinch runner in the seventh and was thrown out trying to steal third. He stayed in the game in center field.
Wicks permitted one run and three hits in six innings in his fourth major league start. He retired his last eight batters.
The Cubs will send RHP Javier Assad (3-3, 2.83 ERA) to the mound against Colorado RHP Chris Flexen (1-7, 7.36 ERA) on Tuesday.
