Rockies 4, Diamondbacks 0
For the second game in a row, Colorado got a terrific outing from a young starting pitcher.
Rookie Christian Friedrich pitched four-hit ball for seven innings in the best start of his young career and the Rockies won for the seventh time in eight games, 4-0 over the Arizona Diamondbacks on Monday night.
The 24-year-old left-hander struck out four and walked two, both in the first inning, to improve to 4-1 in six starts. The performance came one day after 23-year-old Alex White surrendered just two hits in 6 2-3 innings in the Rockies' 3-2 win over the Los Angeles Dodgers.
''Me and Whitey know each other pretty well,'' Friedrich said. ''Us coming in and doing a good job, it's just fun to help out the team and get wins.''
Wilin Rosario had a solo home run and an RBI infield single for the Rockies, who snapped a five-game Chase Field losing streak. Joe Saunders (3-4) allowed four runs on 11 hits in 6 2-3 innings to take the loss.
With the victory, the Rockies pulled within a half-game of Arizona for third in the NL West.
Manager Jim Tracy said Colorado's recent success is simple to explain.
''The competitiveness of our starting pitching has improved immensely,'' he said. ''Over the course of the last two days, that's 13 2-3 innings from two young kids and two great efforts, from both White and Friedrich. The more times we're able to do that, the more confidence they develop, the more they start to believe in themselves, the more they learn.''
Rosario not only sparked the offense, as catcher he nursed Friedrich through a somewhat shaky start to the game.
''I definitely didn't have a feel for the fastball. It just wasn't coming out right,'' Friedrich said. ''Willie started calling some other pitches off-speed and we got out of the jam. He had the confidence in me to throw those breaking ball pitches and it worked out.''
The reigning division champion Diamondbacks, off to a sputtering start to the season - especially at home, had won three of four, all on the road, entering the contest, the opener of a six-game home stand.
''We weren't able to swing the bats at all,'' Arizona manager Kirk Gibson said. ''It has been a trend. You got to score runs. We didn't score any runs. You are never going to win if you don't score. This wasn't a good game for us.''
The Rockies got two more in the second after Todd Helton stretched his hitting streak to 10 games with a leadoff double, then Jordan Pacheco singled to put runners at first and third. Rosario beat out a grounder to shortstop for an infield hit and brought Helton home. DJ LeMahieu singled and Pacheco scored on catcher Henry Blanco's passed ball to make it 3-0.
The Rockies added a run in the fourth when, on a 3-0 pitch, Rosario hit one into the swimming pool area in right-center, his ninth home run of the season.
Tracy said it's the second time Rosario has hit a home run on a 3-0 count.
Arizona loaded the bases in the first but came up empty. Willie Bloomquist drew a leadoff walk, then Paul Goldschmidt extended his career-best hitting streak to 13 games with a two-out double to put runners on second and third. Chris Young walked, but Josh Kubel's fly out to center ended the inning.
The Diamondbacks threatened again in the fourth when Aaron Hill led off with a double and advanced to third when Justin Upton grounded out, but Friedrich struck out Goldschmidt and Young. Gerardo Parra's pinch-hit double led off the Arizona eighth and Hill drew a one-out walk. Upton grounded in to a fielder's choice and, with runners at first and third, Belisle struck out Goldschmidt to end the inning.
