"I saved the ball and I will put it in the house with all the other stuff I have," he said. "I don't keep every ball, just the first ones (with a new team)."
Hernandez pitched into the seventh and benefited from a five-run fourth inning to earn his first win since being acquired in a trade by Arizona, and the Diamondbacks defeated the Colorado Rockies 9-5 Wednesday night
Hernandez (10-9) went 6 2/3 innings and gave up five runs and 11 hits in his second start since coming over from Washington on Aug. 7. He is 5-0 with four no-decisions in his last nine starts and hasn't lost since June 20 at Boston.
"He got us what we needed," Arizona manager Bob Melvin said. "We were looking for seven, and we were just one out short of that."
"It was good that we didn't have to bring our closer in and just had to use two guys," Melvin said.
The offense had a lot to do with that, too.
"The two-out hits were big, eight of our runs were two-out runs," Melvin said. "Not only is it big psychologically for us offensively, but it's tough on the opposing side."
Colorado starter Aaron Cook (8-11) was touched for nine runs and 11 hits over 6 2/3 innings. Todd Helton had three hits and an RBI for Colorado.
"We didn't show up," Colorado manager Clint Hurdle said. "We couldn't throw a punch after the tough 18-inning loss on Tuesday."
Hernandez had a rough start. The Rockies loaded the bases and scored two runs in the first inning after two outs on a single by Helton, a double to center by Garrett Atkins and a walk to Brad Hawpe. Yorvit Torrealba singled up the middle to score two.
The Rockies had gone 13 innings without a scoring.
Byrnes scored Gonzalez and Chad Tracy with a two-out single to center in the third inning to tie the game at two.
"Byrnes got a big hit for us in the third inning to tie the game up, and with Livan pitching and his track record, we had a lot of confidence," Gonzalez said. "We know he is going to throw strikes and work fast and keep the ball around the plate."
The Diamondbacks batted around and scored five runs in the fourth inning, starting with Green's leadoff home run, his 11th of the year.
Stephen Drew, Orlando Hudson, Gonzalez and Tracy followed with RBI hits to make it 7-2. Gonzalez and Tracy each hit doubles in the inning.
"I got the ball up a little bit and they hit three or four balls hard on me," Cook said. "It was all part of the worst start of my career."
The Diamondbacks added two runs in the seventh inning on Carlos Quentin's two-out single and an RBI double by Snyder to make it 9-2.
Hernandez appeared to tire in the Colorado seventh, giving up back-to-back triples to Ryan Spilborghs and Cory Sullivan to start the inning. Helton reached the right-hander for an RBI single and Clint Barmes scored on a double-play grounder to make it 9-5.
Hernandez walked Hawpe before giving way to Luis Vizcaino, who struck out Torrealba to end the inning.
"He is a competitor," Helton said of Hernandez. "He will be around the plate and do just enough to win."
