Jones, who had the Orioles' two RBIs, singled with one out in 10th to start the rally. He advanced to third on Jonathan Schoop's single before scoring. The Orioles' fifth walk-off win of the season ended the Rockies' four-game winning streak and pushed Baltimore's win streak to five.
The Rockies tied the game in the fourth on Nolan Arenado's 26th homer and took the lead for the first time in the seventh when David Dahl picked up his first career hit and scored on Mark Reynolds' single, but they couldn't hold on to it.
