DENVER -- When the ball left Ty Wigginton's bat in the eighth inning Wednesday night, D-backs right-hander Ian Kennedy thought it might be a routine fly ball.
Standing in center field, Chris Young knew it was going to travel farther than that.
"I knew he hit it good, and with [the] Colorado air it does keep on going and you don't have a chance at it," Young said. "But off the bat I thought I had a chance at it."
Young raced back and leaped at the wall to rob Wigginton of a game-tying home run as the D-backs hung on for a 2-1 victory that lifted them above the .500 mark and into sole possession of second place in the National League West.
"Honestly I thought it was a popup, but it's hard for me to tell," Kennedy said. "I just watch the outfielders. It happens in the big leagues a lot, where they hit balls square and you can't tell if they hit them too high or what. I just usually watch the outfielders. That was one of the best catches I've ever seen. I may owe him dinner for that. That was pretty exciting. It was really, really awesome, I don't know how to describe it."
Young also drove in what proved to be the winning run with a bloop single to left in the sixth.
It was the second time in his career that Young has taken away a home run. On Aug. 1, 2007, he robbed the Padres Mike Cameron of a grand slam at PETCO Park.
"You practice for it," Young said. "It's exciting just because of the game situation. Ian pitched his behind off tonight. He really had an amazing game and right there as a defense your only goal is to go out there and help him out. He was battling and battling and battling, so you don't want him to come out with a no-decision there. I tried to get back to the wall as fast as I could and try to make the play as easy as I could. Sometimes guys will kind of drift to the wall and it's a little tougher to get the angle on the ball, so I just tried to get back there as fast as I could and make the play."
Kennedy (6-1) allowed one run on seven hits while walking two and striking out three to earn the win. Kennedy has now won three straight starts and his last five decisions.
It was Kennedy's first-ever win against the Rockies in his eighth career start. Closer J.J. Putz pitched a perfect ninth to record his 14th save in 14 opportunities.
"Tonight I'm going to tip my cap to Kennedy," Rockies catcher Chris Iannetta said. "He pitched really well. He kept the ball down. He didn't make a mistake over the middle of the plate for the most part the whole game -- maybe the one mistake that he made was the pitch to 'Wiggy,' and Chris Young made an outstanding play."
Young wasn't the only one to make a big play behind Kennedy.
In the first inning with one out, Seth Smith singled and when Carlos Gonzalez followed with a single to left, Gerardo Parra caught Smith rounding second a little too far and threw behind him for a key out.
"I don't know how many guys are going to make that play," D-backs manager Kirk Gibson said. "Parra just came up and Smith made a normal rounding of the base, and I wouldn't think he could throw me out either. 'G' just threw a laser right on his foot. Just an outstanding play, and certainly had a huge impact on the game."
Rockies starter Jason Hammel (3-4) was not given the same defensive support and wound up as the hard-luck loser. The right-hander allowed five hits in his seven innings of work and both of the runs he gave up were unearned.
The Rockies grabbed a 1-0 lead in the fourth when Smith led off with a double, advanced to third on a wild pitch and scored on Todd Helton's sacrifice fly to left.
Meanwhile, the D-backs could do little against Hammel as they mustered just two hits through the first five innings.
In the sixth, Ryan Roberts led off with a grounder to short that Alfredo Amezaga fielded cleanly but threw high to first and Roberts was able to slide under the tag of Helton.
Kelly Johnson followed with a double to put runners at second and third and Justin Upton drove in Roberts with a grounder to short.
One out later, Young gave the D-backs the 2-1 lead, one that he would later make sure stayed intact.
