DENVER -- Right-hander Rubby De La Rosa sailed through 7 1/3 innings as the D-backs won their fifth straight and sent the Rockies to their seventh straight home loss, 5-1, at Coors Field on Tuesday night.
De La Rosa allowed one run and four hits while striking out six.. His work kept the Rockies quiet until the D-backs could erupt for four runs off Rockies starter Chris Rusin in the sixth, as Welington Castillo and Chris Owings delivered doubles. Paul Goldschmidt added his seventh homer of the season, a solo shot off Gonzalez Germen, in the seventh.
"It's just great to see him free and easy swinging the bat," D-backs manager Chip Hale said of Goldschmidt, who got off to an uncharacteristic slow start this year. "It's really important for him, he feels good about it."
Rusin, who held the D-backs to one hit in five innings in a May 1 start at Chase Field, gave up four runs on 10 hits in 5 2/3 innings Tuesday. The seven-game skid is two games fewer than the club record, set July 25-Aug. 18, 1993 -- the club's inaugural season at old Mile High Stadium. It's the longest home skid since they dropped seven straight in 2012 -- July 17-Aug. 1. More >
If the Rockies drop Wednesday afternoon's series finale they will match their longest Coors Field losing streak -- eight games over two seasons, Sept. 15, 2011 to April 9, 2012. They are now 4-10 at home this season.
"It's concerning," Rockies manager Walt Weiss said. "Usually this is where we play really well historically. So it's strange, but I do believe we'll turn it around. As we get deeper into the season, we'll turn this thing around at home and start winning games again."
MOMENTS THAT MATTERED
Rubby likes Coors: De La Rosa's success at Coors Field continued Tuesday night. De La Rosa has appeared in five games, four as a starter, there in his career and he is 3-0 with a 2.73 ERA.
"Everything," De La Rosa said when asked what was working for him. "I tried to keep the ball down tonight and I had a good breaking ball tonight. It's a really good team so I just tried to get ahead of them." More >
Big-arm CarGo: It's a tough stretch offensively for right fielder Carlos Gonzalez, who hasn't driven in a run in 15 games and hasn't homered in 21. But he delivered a strong, two-hop throw from right field to beat Yasmany Tomas to the plate to keep the game scoreless in the fourth inning.
Bottom comes up big: It was the bottom of the Arizona order that did the damage during the decisive sixth. Seventh-hitter Chris Owings delivered an RBI double and that was followed by an RBI single from Nick Ahmed and a safety squeeze by De La Rosa..
"That was something we worked on hard this spring so that was good to see," Hale said of the squeeze.
There goes the momentum: Leadoff hitter Charlie Blackmon singled to open the bottom of the first and De La Rosa balked him to second. But Trevor Story, after running the at-bat to nine pitches, whiffed on an 84 mph slider (a familiar story against De La Rosa), Gonzalez took a called third strike and Nolan Arenado popped to Goldschmidt in foul ground.
"You want early momentum," Weiss said. "We've stalled here the last few days offensively. Not sure if we're a little gassed from the 19 straight [actually, a inclement weather postponement against the Pirates on April 28 was an off-day of sorts] and tough road trip, but I do know that's the same team that scored 13 in one inning a few days ago in San Francisco. We've definitely stalled here the last few days but we'll get it going again."
Hale challenged whether Rockies catcher Tony Wolters blocked Tomas from the plate illegally upon receiving Gonzalez's fourth-inning throw. However, officials ruled that Wolters was within the rules in going into the basepath to field Gonzalez's throw. After Tomas slid into Wolters' leg and bounced past the plate, Wolters scooted over to tag him.
D-backs:Robbie Ray will take the mound for the D-backs on Wednesday afternoon as they wrap up a three-game series with the Rockies at Coors Field. The game also caps a nine-game road trip which also included stops in Miami and Atlanta..
Rockies: Righty Chad Bettis (3-2, 4.40 ERA), who held the D-backs to three runs and six hits in six innings in a win at Chase Field on May 1, will start against Arizona on Wednesday at 1:10 p.m. MT.
