The Colorado Rockies have been on a roll since the season started and will try to extend their winning streak to seven games when they open a three-game series Friday versus the Arizona Diamondbacks.

The Rockies are 11-4 and have the second best record in the National League and completed a three-game sweep of the New York Mets with Thursday's 11-3 pounding of the visitors at Coors Field. Carlos Gonzalez went 3-for-5 with an RBI and Troy Tulowitzki, Wilin Rosario and Todd Helton all drove in a pair of runs for Colorado, winners of six straight.

Colorado pounded out 17 hits and put the game away with a six-run seventh inning.

"The game is close, and then it seems like seventh, eighth or ninth [innings], we've been putting crooked numbers up there and putting some games away," Rockies manager Walt Weiss said. "It's just tough for a pitcher to make quality pitches throughout the lineup."

Rockies starter Jon Garland allowed two runs over seven innings for the win and Chris Volstad tossed two innings of one-run ball.

The Rockies are a perfect 6-0 at Coors Field this season and are riding the longest winning streak in the NL. Boston has also won six straight.

Jhoulys Chacin gets the call for Colorado Friday and he is 2-0 with a 1.96 earned run average in three starts this season. In Saturday's 9-5 win at San Diego, Chacin limited the Padres to two runs in five innings, striking out three and walking two.

The right-hander has faced Arizona 10 times in his career (9 starts) and owns a 3-2 record with a 2.81 ERA.

Arizona will continue its nine-game road trip in the Rocky Mountains and salvaged the finale of a three-game series against the New York Yankees with a 6-2 triumph in 12 innings on Thursday.

Martin Prado and Didi Gregorius both homered, while Paul Goldschmidt and Cody Ross each had three hits. Former Yankee Eric Chavez knocked in three runs with a double during a four-run top of the 12th inning.

Patrick Corbin held the Yankees to one run and two hits over seven innings despite not factoring in the decision. Heath Bell pitched an inning of relief to pick up the win.

"Their pitching, our pitching they were good," Prado said. "Fortunately for us, we scored a couple runs when we needed it."

The Diamondbacks hope to get a similar showing from starter Ian Kennedy when he toes the rubber Friday. Kennedy was roughed up in his last outing, a 7-5 loss to the Los Angeles Dodgers on Saturday. Kennedy was tagged for six runs and 10 hits in 5 2/3 frames and fell to 1-1 in three starts with a 5.79 ERA.

Kennedy, a right-hander, will face Colorado for the 13th time in his career and owns a 3-2 record to go along with a 2.71 ERA in the first 12 meetings.

Arizona and Colorado are meeting for the first time this season and the Diamondbacks won 10 of the 18 matchups with their NL West foes a year ago.
