They'll try for a third straight win over the Rangers on Wednesday night when the interleague series shifts to Arlington.
One night after recording 13 hits in an 8-2 win over Texas (17-16), Colorado pounded out a season-high 21 in Tuesday's 12-1 rout at Coors Field. Carlos Gonzalez had five hits, Troy Tulowitzki added three and Nolan Arenado extended his hitting streak to 26 games for the Rockies (21-14), who averaged 8.2 runs and hit .373 during a 5-1 homestand.
''They can freakin' hit," losing pitcher Robbie Ross Jr. said. "They're swinging hot sticks right now."
A winner in 14 of 19, Colorado has reached double digits in runs seven times already after scoring 10 or more nine times in all of 2013. The Rockies are 4-1 in interleague play after going 7-28 against the AL the past two seasons.
''We got guys up and down the order and on the bench that can really swing it,'' said Arenado, batting .353 with 18 RBIs during a hitting streak that is one game shy of matching Michael Cuddyer's team-record 27 from last season.
Hitting a major league-best .421, Tulowitzki is 13 for 19 with eight RBIs in five games this month. He's batting .459 with 17 RBIs in his last 17 interleague contests.
Gonzalez, who recorded the third five-hit game of his career, is 12 for 20 with seven RBIs in four games against the AL in 2014.
Though the Rockies are hitting .355 and averaging 7.6 runs at Coors, they're batting .254 and scoring 4.0 runs per game away from home heading into this seven-game trip.
Colorado will try to beef up its road numbers against Colby Lewis (2-1, 4.22 ERA), who allowed eight runs and 12 hits over four innings of an 11-7 home loss in his only appearance against the Rockies in 2012.
However, the right-hander is 2-0 with a 3.38 ERA in his last three starts after yielding two runs in 5 2-3 innings of a 5-2 road victory over the Los Angeles Angels on Friday.
"He had a good changeup and moved the ball around in the zone," manager Ron Washington told the Rangers' official website. "It was nice to see him go out there and throw like Colby of old."
The Rangers have dropped seven of nine and now head home, where they were outscored 25-4 while being swept in a three-game set by Oakland last week.
They'll face Jorge De La Rosa (3-3, 5.11), who went 0-3 with a 7.58 ERA in his first four starts but has a 2.50 ERA while winning his last three. The left-hander allowed three runs in six innings of a 10-3 home win over the New York Mets on Friday.
"That was the problem in the beginning of the season: I didn't have my command and tried to do too much," De La Rosa told the Rockies' official website. "The last few games, I've tried to be relaxed, have fun and throw quality pitches."
He's generally been relaxed at home, going 7-0 with a 2.67 ERA in his last 10 starts at Coors, but the road has been a different story. De La Rosa is 3-4 with a 6.00 ERA in his last eight outings away from Denver.
Texas slugger Adrian Beltre is 0 for 4 versus De La Rosa, but after homering Tuesday is batting .420 with 12 home runs and 39 RBIs in his last 36 games against the Rockies.
