Charlie Blackmon and Michael McKenry each had three hits and an RBI and Justin Morneau added two hits and drove in a run for the Rockies, who won for only the second time in their last 16 road games. Rob Scahill (1-0) pitched a scoreless ninth to earn the win and Adam Ottavino worked around a two-out single in the 10th for his first major-league save.

Luis Valbuena homered among three hits and knocked in three runs for the Cubs, who also got three hits from Ryan Sweeney. Wesley Wright (0-2) gave up two runs in the 10th to suffer the loss, allowing Barnes' tiebreaking single and throwing a wild pitch that allowed Drew Stubbs to score.

Colorado grabbed an early 3-0 lead on Morneau's RBI single in the first and run-scoring doubles from Charlie Culberson and Blackmon an inning later. John Baker, Tuesday's hero, got the Cubs on the board with an RBI double in the fifth, but the Rockies got the run back on McKenry's run-scoring double in the sixth.

Valbuena's two-out infield single plated the Cubs' second run in the bottom of the inning, and Chicago rallied in unlikely fashion in the eighth. Stubbs muffed Starlin Castro's fly ball just in front of the ivy-covered wall to keep the inning alive, and Valbuena followed by driving a 3-2 pitch from Tommy Kahnle out to right to tie it at 4.

GAME NOTEBOOK: Chicago has allowed at least one run in the first inning in seven of its nine games on the current homestand and has been outscored 14-2 in the opening frame during that stretch. … Rockies LHP Brett Anderson struck out nine and allowed two runs on 11 hits over seven innings while Cubs LHP Travis Wood racked up a career-high 11 strikeouts but yielded four runs and eight hits over six innings to run his winless streak to eight starts. … The Cubs acquired LHP Felix Doubront from Boston for a player to be named later and reportedly are close to dealing 2B/OF Emilio Bonifacio ahead of Thursday's non-waiver trade deadline.
