The Colorado Rockies (30-85) wrap up their series at Chase Field on Sunday against the Arizona Diamondbacks (55-61) with both teams heading in opposite directions.

With the Rockies on a five-game losing streak and missing key players including Kris Bryant, this matchup sets up as a potential offensive showcase against one of baseball's weakest pitching units.

Arizona Diamondbacks vs. Colorado Rockies preview
The Rockies arrive in Phoenix having dropped five straight games and sitting dead last in the NL West at 30-85, trailing first place by a staggering 36.5 games.
Colorado's offensive struggles are well documented - they rank 29th in runs scored and dead last in on-base percentage at .295, with only Hunter Goodman providing consistent production (.282 average, 22 homers).
On the mound, it gets even uglier for the Rockies, as they own baseball's worst ERA at 6.01 and are allowing opponents to hit .300 against their pitching staff.
Arizona enters with modest momentum after winning four of their last six, though they still trail the division by 12 games and recently traded away power hitter Eugenio Suarez to Seattle.
Sunday's pitching matchup favors the home side, with Colorado sending out Tanner Gordon (2-4, 6.59 ERA) who has been hammered for 19 hits and 13 runs over his last 5.2 innings.
The Diamondbacks counter with Brandon Pfaadt (11-7, 5.02 ERA), who has been solid in four of his last five starts and should feast on a Rockies lineup that has managed just one run in the series opener.
