PHOENIX -- Chase Field is nothing if not hitter-friendly.
Call it Coors Field SXSW.
Arizona and Colorado combined to score 21 runs in the Diamondbacks' 12-9 victory at Chase Field in the first game of a three-game series Monday, continuing the Runs-R-Us trend that has defined the series throughout the year.
The Diamondbacks and Rockies combined for 39 runs in the season-opening three-game series at Chase from April 4-6, a Rockies' sweep, and not much has changed since.
In the three series at Coors Field starting May 9, the teams combined for 36, 65 (four games) and 47 runs.
Colorado left-hander Jorge De La Rosa and Arizona left-hander Robbie Ray will do what they can to change that in the second game of the series Tuesday. De La Rosa is 8-7 with a 5.00 this season, while Ray is 7-13 with a 4.46 ERA.
Ray has 195 strikeouts and would be the fourth NL pitcher to reach 200 this season, following Washington's Max Scherzer, Miami's Jose Fernandez and San Francisco's Madison Bumgarner. Ray had 119 strikeouts in his rookie season of 2015.
"The biggest thing is just how well I've been able to command the fastball and how my other pitches play off that," said Ray, whose fastball routinely touches 97 mph and stays there throughout his starts.
Arizona used four hits from Yasmany Tomas, including his first career grand slam, and four hits and a homer from Brandon Drury in the slugfest Monday, the 10th time the Diamondbacks have scored at least seven runs in their 17 games with the Rockies this season.
The Diamondbacks also made some historical headway. They had 16 hits, the 12th straight game in which they have had double-digit hits against Colorado. Texas had a 12-game double-digit hit streak against Oakland in 1996, the last major league team do that. Arizona was the first NL team to do that since the Brooklyn Dodgers had a 12-game doublet-digit streak in 1932.
Tomas' slam in the sixth inning rescued the D-backs and gave them a 10-9 lead after they were unable to hold a 5-0 lead after three innings.
"They got some clutch hits and we got some clutch hits," Colorado manager Walt Weiss said.
"They got a few more."
Tomas, not Paul Goldschmidt, leads the Diamondbacks with 29 home runs. Jake Lamb is second with 28 and Goldschmidt is third with 20.
"That ball jumped out of here, but he had good at-bats all night," Arizona manager Chip Hale said of Tomas' slam.
Tomas had 19 homers as a rookie last season after signing a six-year $68.5 million free agent contract. He ended last season as a role player.
"Was he going to be a big home run guy?" Hale said. "We thought he was going to be more gap-to-gap. He has it in him. I didn't think it would come this quickly."
Several Rockies have big numbers in season series, too. Charlie Blackmon was 3-for-4 Monday and is hitting .366 in 66 games against Arizona, the fifth-highest batting average among active Diamondbacks' opponents.
Carlos Gonzalez, who had three doubles and three RBIs Monday, is 13-for-25 (.520) with seven runs and four RBIs in six games at Chase Field this year. He has 29 doubles and 24 homers in 377 career at-bats against Arizona, and his 24 homers are fourth among active players against the Diamondbacks.
