The Colorado Rockies (89-70) completed a four-game sweep of the Philadelphia Phillies (78-81), with a 5-3 victory at Coors Field Thursday afternoon. After starting the week trailing the Cardinals for a wild card spot, the Rockies now lead the NL West by one game and can control its own fate in the final series of the regular season.

In the four games against the Phillies, the Rockies exploded for 39 runs. Although Thursday’s game was not as high scoring as the first three were, Colorado did enough at the plate to win.

David Dahl hit his 14th home run of the season, had a triple and picked up another two RBI in the victory. And Trevor Story launched yet another home run onto the left field concourse in the game as well. The 471-foot bomb was Story’s 83rd extra-base hit and 35th home run in 2018.

Scott Oberg (8-1) was the winning pitcher for Colorado Thursday after tossing an inning and one third of hitless baseball. Antonio Senzatela would have been the pitcher on record if the starter would have been able to go a full five innings, but Senza was pulled with two outs in the bottom of the fifth.

Along with Oberg, Seunghwan Oh and Adam Ottavino each had an inning of work, before Wade Davis closed things out in the ninth.

Following the sweep of the Phillies, the Rockies have an opportunity to secure the first division title in franchise history. If Colorado sweeps Washington at home in the three-game series this weekend, the Rockies will be division champions, regardless of what happens in the Dodgers-Giants series.

Kyle Freeland (16-7) is slated to take the mound for the Rockies on Friday night. Freeland will be facing Joe Ross (0-1) of the Nationals. Ross has only made two other starts this season after missing 14 months due to Tommy John surgery.
