Denver, CO (SportsNetwork.com) - Justin Morneau crushed a two-run homer in the 10th inning that lifted the Colorado Rockies to an 8-6 win over the San Diego Padres on Sunday in the rubber match of a three-game set.

Carlos Gonzalez singled with one out in the home half and Morneau smoked a 3-2 fastball over the wall off Dale Thayer (2-2) two batters later to end it.

"Justin came up big in the end there," Rockies manager Walt Weiss said of Morneau. "I'm really happy for him. He's having a phenomenal season."

The Rockies had a 6-4 lead in the ninth before LaTroy Hawkins blew his first save of the season, serving up a two-run shot by Everth Cabrera.

Nick Masset (1-0) pitched a perfect top half of the 10th for Colorado to earn the win.

Seth Smith opened the scoring with a solo homer to right center in the first to give the Padres an early lead.

Colorado put up a four-spot in the third, with Charlie Blackmon's two-run single coming just before Corey Dickerson's two-run homer to left.

With two outs in the fourth, Cameron Maybin singled and scored on Rene Rivera's double. Will Venable plated Rivera a batter later with a single to center to cut the San Diego deficit to 4-3.

"You know we're going to battle. We're going to (give) 100 percent until the last out," Rivera said. "It was a tough game."

Tulowitzki increased the Colorado cushion with a solo shot to lead off the fifth, but San Diego got the run back in the next inning with a solo blast from Rivera.

In the home seventh, Blackmon and pinch-hitter Drew Stubbs singled to set up a frantic play. Following a 6-4-2-5 double play off the bat of Tulowitzki -- one in which Blackmon was erased at home and Stubbs at second and left the batter on second base -- Gonzalez brought him home with a looping single into center that pushed the spread to 6-4.
