Winners of five straight and nine of their last 10, the Arizona Diamondbacks (68-53) look to complete the sweep of the Colorado Rockies (44-77) on Wednesday afternoon at Chase Field. First pitch is scheduled for 3:40 p.m. ET.
The latest Rockies vs Diamondbacks odds for Wednesday have the Diamondbacks as -218 moneyline favorites with an over/under of 9 (-115o / -105u). Tanner Gordon will take the mound for Colorado, while Arizona is set to hand the ball to Jordan Montgomery. Notably, the Diamondbacks will still be without star second baseman Ketel Marte on Wednesday due to a left ankle injury.

Rockies-Diamondbacks Prediction, Preview
Rockies Betting Preview: The Uninspiring Tanner Gordon
Gordon's MLB tenure has gotten off to a poor start. He is 0-3 through five starts with a fade-worthy 6.15 ERA and 1.33 WHIP.
Unfortunately for the former sixth-round draft pick, his underlying metrics suggest that brighter days aren't ahead. Although he doesn't officially qualify, Gordon would rank in the bottom half of the league in xERA, xBA, average exit velocity, strikeout rate and barrel rate.
Following Gordon is a fade-worthy bullpen. This season, Colorado's relief staff ranks last in ERA, 29th in FIP and 27th in xFIP.
The good news for this pitching staff is that run support may be on the way. The Rockies rank in the top half of the league in hits per game, BA, SLG and OPS.
Diamondbacks Betting Preview: Venomous Snakes Offense
That success at the dish is likely to continue against Montgomery, a pitcher who possesses a 6.37 ERA and 1.68 WHIP through 17 starts this season. Like Gordon, Montgomery's analytics are equally poor as he ranks in the 24th percentile or lower in xERA, xBA, strikeout rate and hard-hit rate.
Also like Gordon, the left-hander is followed by a weak bullpen. Arizona's relief staff ranks in the bottom eight of the league in ERA, FIP and xFIP.
With that said, the D-Backs boast one of the best lineups in baseball. They rank in the top seven in runs scored per game, hits per game, BA, OBP, SLG, OPS and home runs.
Rockies at Diamondbacks Prediction: Over/Under Value
There is little reason to not like the over in this spot. Gordon and Montgomery both rank in the bottom half of the league in xERA, xBA, average exit velocity and strikeout rate.
Both bullpens also rank in the bottom eight of the league in ERA, FIP and xFIP. Meanwhile, both lineups rank in the top half in hits per game, BA, SLG and OPS.
Pick: Over 9.5 (+100 at bet365 | Play to -105)
Moneyline
I'm going to pass on the moneyline.
Arizona is clearly the superior team in this matchup, but there is no way I am backing a team at -230 when Montgomery is one their mound.
Run Line (Spread)
I'm also going to pass on the run line.
I like the Rockies at +1.5, but not at -105 to -118, which is where the market ranges at the time of writing.
Over/Under
Bet the over at 9.5.
