Last Meeting ( Sep 26, 2018 ) Philadelphia 0, Colorado 14

The red-hot Colorado Rockies aim to complete a four-game dismantling of the visiting Philadelphia Phillies when the series concludes on Thursday afternoon. The Rockies have outscored Philadelphia 34-4 while winning the first three games to move into first place in the National League West - one-half game ahead of the Los Angeles Dodgers.

Colorado is riding a six-game winning streak during which it has outscored its opponents 47-7. David Dahl has homered in all three games of the series and is 6-for-14 with nine RBIs for the Rockies, who racked up 16 hits - four homers - in Wednesday's 14-0 shellacking. Trevor Story went 3-for-4 with a two-run blast and has belted eight shots this month despite missing five games due to an elbow injury. Philadelphia's late-season decline includes a season-worst seven-game slide and losses in 26 of its last 36 contests.
