Chris Iannetta had two hits and three RBIs, and Antonio Senzatela pitched seven strong innings as the Colorado Rockies kept pace in the National League playoff race with a 5-1 victory over the Arizona Diamondbacks on Saturday in Phoenix.

Iannetta's two-out, two-run single highlighted a four-run third inning off Arizona left-hander Patrick Corbin.

Senzatela retired the first 14 batters he faced as the Rockies (84-70) remained second to the Los Angeles Dodgers in the NL West and 1 1/2 games behind the St. Louis Cardinals for the second NL wild card.

Colorado's Charlie Blackmon had two hits to extend his hitting streak to 14 games, tying a career high. DJ LeMahieu added two hits for the Rockies, who won their second straight in the series after being swept by the Dodgers earlier in the week.

A.J. Pollock's homer in the fifth inning broke up Senzatela's perfect game, and the Diamondbacks had only two other hits and did not get another runner as far as second base. Arizona has lost 11 of 14 and would be eliminated from playoff contention with one loss or one St. Louis victory.

Senzatela (6-6) gave up one run on three hits, struck out four and did not walk a batter while tying a season high for innings pitched.

The Rockies finish the three-game series at Arizona on Sunday before playing their final seven games at home, against the Philadelphia Phillies and the Washington Nationals, both eliminated from playoff contention.

Colorado scored four runs off Corbin (11-7) with two outs in the third inning for all the offense it needed. Blackmon was hit by a pitch and Nolan Arenado and Ian Desmond walked to load the bases before Iannetta singled to center to drive in two. David Dahl and Garrett Hampson followed with RBI singles before Senzatela struck out to end the inning.

Corbin threw 44 pitches in the third and left for a pinch hitter in the last of the inning, his shortest start of the year. He gave up five hits and four walks and struck out five in what could be his final home start for Arizona. He is a free agent this winter.

Pollock's homer, his 19th, made it 4-1. Iannetta walked with the bases loaded to force in the Rockies' final run in the ninth.
