Recent Form:

The Arizona Diamondbacks have been on a little run recently. They have won 3 games in a row and have won 6 of their last 7. The 7 games they won were all at home though, they will be on the road for this game where they have not done too well. The Diamondbacks have lost 4 games in a row away from Chase Field. They have averaged more than 5 runs scored per game in their last 7. When on the road, they have only scored more than 2 runs in a game on 1 occasion. The Arizona Diamondbacks Thursday game was during the day so they will get a bit of a rest before this one. They are facing a Colorado Rockies team that is playing very well at the moment. The Rockies managed to complete a three-game sweep of the San Diego Padres in Wednesday’s finale, getting Thursday night as a rest period. The Rockies have played with some kick at home recently, winning their last 7 games straight when playing at home. They have scored 6 or more runs in each of their last 3 games. The result of tonight's game on Friday is still pending for this National League West clash.

Series History:

The Colorado Rockies head-to-head have the winning record here as they are 7-6 against this Diamondbacks team this season. The Rockies have won 4 of their last 6 games against Arizona. Colorado has been even better in their home games against the Diamondbacks sporting a 5-1 record this year when playing them at Coors Field.

Statistical Comparison:

The Arizona Diamondbacks have not had that great a year with their hitters, they are ranked in the bottom 10 of the MLB for most categories. They are ranked 22nd in the league for batting average (.236), 23rd in the league for RBI (484), 16th in the league for hits (973), and they are ranked 20th in the league for OBP (.311).

They are ranked 29th in the league for ERA (5.21), 29th in the league for saves (17), 28th in the league for strikeouts (946), and they are ranked 29th in the league for WHIP (1.44).

Diamondbacks vs Rockies 

Game Preview:

Saturday night will be game 2 of the Arizona vs Colorado series on the schedule. The Colorado Rockies definitely have the advantage in this three-game series matchup when it comes down to the stats. The D-backs are one of the worst teams in the league in every area, they now have the lowest record in the National League.. The Rockies have them beat in both hitting and pitching. Friday will see Tyler Gilbert, who pitched a no-hitter in his last start, and Austin Gomber battling on top of the mound. Saturday night will see Zac Gallen and Kyle Freeland as the starting pitchers for this MLB game.
Zac Gallen will be the projected starting pitcher for the Arizona Diamondbacks on Saturday and he has seen better seasons. Gallen is 1-7 this year with a 5.03 ERA. He has been credited with 7 straight up losses in games where there was a decision made. His team only has 1 win in his last 12 starts for them. He has allowed 21 total earned runs in his last 5 starts, averaging 4 or more allowed per game. In the last 3 games that he started in, the opposition scored at least 7 runs in each game.
Kyle Freeland will be throwing the first pitch for the Rockies in this game. He is 4-6 this season with a 4.40 ERA. He has pitched alright in his last few starts getting awarded with the win in his last 3 starts. Prior to these 3 wins he had been credited with the loss in 4 straight starts. He has allowed 7 total earned runs in his last 3 games, averaging just a little over 2 runs allowed per game. This will be the first time that he has seen this Diamondbacks lineup this season. With these two pitchers starting, and considering the ballpark, there could be a lot of runs scored for either side in this game. 
BetMGM sportsbook has the current line for the Diamondbacks odds listed as juicy underdogs. The Colorado Rockies odds are very steep in this one. In a bad pitching matchup like this, the value just might be on them, making an Arizona Diamondbacks prediction.

Notable quotes:

"Everything was working today. Kept that same feel that we've had going. Quick outs, weak contact, faster-paced game." - Madison Bumgarner on their big 6-2 win against the Phillies on Thursday.
"The five guys who pitched, they got punched a little but they put their dukes up and responded back with some swings of their own." - Bud Black on the pitching performance his team gave in the final game of the series sweep of the Padres.


Arizona: 18-11 on the money line against NL teams that are allowing over 4.5 runs per game this season
Colorado: 25-12 on the moneyline at home against NL teams with a batting average worse than .245.
