DENVER -- Last year, the San Diego Padres' feeble offense severely limited the team's ability to stage a comeback. The Padres now possess legitimate firepower after their winter makeover.

San Diego struck for four runs in the eighth inning Tuesday to overhaul the Colorado Rockies 7-6 at Coors Field. The Padres earned their ninth win in 11 games, while the Rockies lost their fifth straight.

At 10-5, the Padres are off to their best 15-game start since they were a franchise-best 12-3 in 1998. They went to the World Series that season.

The Padres' comeback came at the expense of Boone Logan (0-1). With Colorado leading 5-3, the left-hander replaced Rafael Betancourt with one out and a runner on first in the eighth, and he hit first baseman Yonder Alonso with a 1-2 pitch. Pinch hitter Yangervis Solarte followed with a run-scoring single to make it 5-4.

Shortstop Alexi Amarista's safety squeeze bunt was fielded by Logan, who threw home in time to get Alonso. However, center fielder Wil Myers followed with a game-tying single, and catcher Derek Norris added a two-run double.

The Padres, whose .226 average last year was the lowest in the majors, took an early 2-0 lead, only to have the Rockies tie the game in the fourth and go ahead 5-2 with a three-run fifth that included center fielder Charlie Blackmon's two-run triple.

The Padres cut the lead to 5-3 in the seventh on Myers' double off Brooks Brown. Brandon Maurer (1-0) pitched a scoreless seventh after starter Brandon Morrow gave up five runs in six innings. Closer Craig Kimbrel allowed a leadoff homer in the ninth to catcher Nick Hundley, who also tripled home a run in the fourth. However, Kimbrel retired the next three batters to earn his fifth save.

Myers had two RBIs and a game-high three hits, while Norris and Padres third baseman Will Middlebrooks added two hits apiece.

Rockies starter Tyler Matzek, who issued a career-high six walks through five innings, eased out of trouble in the fifth and kept the game tied at 2-2 when he got right fielder Matt Kemp to ground into an inning-ending double play after an error by third baseman Rafael Ynoa loaded the bases. That was the final inning for Matzek, who threw just 44 of 85 pitches for strikes but escaped with minimal damage.

NOTES: Padres RHP Brandon Morrow reached base for the first time in his career when he walked in the fifth. He was hitless in 19 at-bats without drawing a walk or getting hit by a pitch to that point. ... Rockies 3B Nolan Arenado (left wrist strain) and LF Corey Dickerson (plantar fasciitis in left foot) didn't start, though Dickerson appeared as a pinch hitter. ... Padres RHP Ian Kennedy (strained left hamstring) rejoined the team after throwing 81 pitches in six innings Monday in an extended spring training game at Peoria, Ariz. He could return to the rotation Saturday against the Dodgers. ... Padres RHP Odrisamer Despaigne singled Monday for his first major league hit. He began his career 0-for-30, the second-longest hitless streak to start a career, trailing only RHP Joey Hamilton, who went 0-for-57.
