DENVER -- The Colorado Rockies parlayed a strong start by Jordan Lyles, shutdown relief pitching and another home run by Corey Dickerson into a 2-1 win over the San Diego Padres on Thursday.

The victory gave the Rockies a split of the four-game series and came after their 5-4 win Wednesday night on first baseman Daniel Descalso's walk-off single that ended a five-game losing streak. The Rockies (9-7) are 3-2 in one-run games overall and 2-2 at Coors Field.

The Padres (10-7) lost back-to-back games for the first time this season.

Lyles, who pitched six innings in each of his first three starts, worked 6 2/3 innings and joined Kyle Kendrick as the only Rockies starters to reach the seventh this season. Lyles (2-1) left after walking Alexi Amarista, putting runners on first and second for pinch hitter Justin Upton.

Scott Oberg, who began his second tour this season with the Rockies when they recalled him from Triple-A Albuquerque, relieved Lyles and struck out Upton on a 95 mph fastball.

Dickerson led off the fifth with a first-pitch homer. It was his third homer in two days -- his fifth of the season -- and put the Rockies ahead 2-1.

That was the final inning for Tyson Ross, who needed 106 pitches to get through the fifth and was fortunate to allow just two runs. He walked four and twice left the bases loaded.

Ross (1-1) issued three walks in the first, the final one to Descalso with the bases loaded. But Ross then avoided a big inning by striking out center fielder Drew Stubbs. The Rockies' only hit that inning was third baseman Nolan Arenado's slow grounder to Ross.

Ross gave up two singles and a two-out walk to Stubbs to load the bases in the third but struck out Lyles.

Lyles issued his first walk with two outs in the fourth to infielder Yangervis Solarte, following right fielder Matt Kemp's infield single, and first baseman Yonder Alonso singled home a run.

Rafael Betancourt came on after Oberg and pitched the eighth. He gave up a two-out double to second baseman Cory Spangenberg but got Kemp to pop out.

John Axford issued a one-out walk in the ninth. But he struck out Will Venable and Amarista to earn his second save of the season and the 118th of his career.

NOTES: Rockies INF Rafael Ynoa's double in the eighth was his first hit as a pinch hitter. He was previously 0-for-8 with a walk in that role. ... Padres 3B Yangervis Solarte batted fourth for the first time in his career. He entered the game with 572 plate appearances and had batted in every other position in the lineup. ... San Diego RHP Ian Kennedy (left hamstring strain) will start Saturday when he is eligible to come off the 15-day disabled list. RHP Odrisamer Despaigne, who made two starts in Kennedy's absence, will return to a long relief role. ... Rockies INF Daniel Descalso made his fourth start and appeared in his 11th game at first base. The previous three starts were last year with the St. Louis Cardinals. Descalso became the backup first baseman when Wilin Rosario was optioned to Triple-A Albuquerque on Wednesday. ... Colorado RF Carlos Gonzalez was not in the lineup. He's hitting .179 (17-for-56) and has one hit in his past 21 at-bats and none in his past 13 at-bats.
