Rockies 5, Diamondbacks 4
DENVER -- Pinch hitter Ben Paulsen's two-run single capped the Rockies' four-run ninth inning, and Colorado rallied to beat the Arizona Diamondbacks 5-4 Monday.
Paulsen delivered on an 0-2 pitch from Matt Reynolds for his second career walk-off hit.
Diamondbacks closer Brad Ziegler entered with 22 consecutive saves, but he couldn't add to his streak.
The Rockies were 0-for-15 with runners in scoring position before third baseman Nolan Arenado lined a Ziegler pitch for a two-run single off the top of the left field wall with one out in the ninth. The hit cut Arizona's lead to 4-3.
Ziegler (0-3) who got right fielder Carlos Gonzalez to fly out for the second out. Second baseman DJ LeMahieu hit a bouncer off Ziegler's glove. The reliever ran for the ball, threw while falling down, and the ball sailed over first base, putting runners on second and third for catcher Nick Hundley, who walked.
Reynolds, a left-hander who began his career in the Colorado organization, came on to face Paulsen.
Arizona rookie left-hander Robbie Ray was on the verge of winning for the first time in nine starts since July 7. He has lost six straight decisions, winding up with a no-decision Monday after allowing one run in 5 2/3 innings.
Center fielder A.J. Pollock hit a two-run homer in Arizona's three-run third, hammering an 0-2 changeup deep into the left fields stands for his 14th homer. Right fielder Ender Inciarte and left fielder David Peralta each had run-scoring singles, Inciarte in the third and Peralta with two outs in the fifth, as the Diamondbacks built a 4-1 lead.
That damage came against starter Chad Bettis, who allowed a career-high 11 hits -- eight singles, Pollock's homer and first baseman Paul Goldschmidt's double ahead of Peralta's run-scoring single -- and four runs in six innings.
Simon Castro (1-0) retired the six batters he faced to earn his first major league win in his third appearance with the Rockies and seventh overall in the big leagues.
Rockies center fielder Charlie Blackmon went 3-for-4 with a walk and finished a home run shy of the cycle.
