Thomas Field, playing in right field as a result of Ty Wigginton being ejected in the 1tth inning for arguing balls and strikes, led off the top of the 13th with a walk and advanced to third on an Eric Young Jr bunt single and Houston throwing error. Young moved over to second on catcher's indifference and saw Dexter Fowler reach on an intentional walk.
Chris Nelson drew a bases loaded walk to put the Rockies up, 3-2, and Wilin Rosario hit a sac fly for the insurance run. Jordan Pacheco ended the inning with a fly out, but Rafael Betancourt came in for the bottom of the inning and struck out two for his seventh save of the season.
Jason Hammel pitched well enough to leave lasting consideration for a rotation battle in the spring. He allowed two runs in seven innings, a sacrifice fly in the first inning and a Brett Wallace home run in the second inning. Astros starter J.A. Happ allowed two runs in seven innings as well. Pacheco hit a two-run double off him in the fourth inning.
The Rockies (71-87, 33-44 away) conclude this series on Sunday at 12:05 p.m. MT. Kevin Millwood and Lucas Harrell take the mound.
