SAN DIEGO – Edinson Volquez pitched shutout ball into the seventh inning and Alexi Amarista hit a two-run double as the San Diego Padres beat the Seattle Mariners 2-0 on Sunday.
Volquez (4-7) was in command as he allowed just four singles in 6 2-3 innings and was not hurt by the control issues that have hampered him this season.
Volquez, who leads the majors in walks with 55, walked three but was rarely stressed by the Mariners. The right-hander combined with three relievers for the five-hitter.
Huston Street pitched a perfect ninth inning for his 10th save in as many chances.
It was an emotional day for the Padres, who found out that longtime bullpen coach Darrel Akerfelds died from pancreatic cancer on Sunday morning.
Volquez won for just the second time in his last eight starts. He had been 1-5 with a 5.72 ERA in his last seven, while walking at least three in each of those outings.
Hector Noesi (2-9) extended his career-high losing streak to six games. He's tied with Baltimore's Jake Arrieta for the major league lead in losses.
Noesi had one of his better recent outings as he allowed two runs on seven hits in six innings. The right-hander has not won since May 6 against Minnesota.
Seattle, which has lost three of four, did not have a runner advance past second base. The Mariners had scored 32 runs in the first five games of the road trip.
The Padres loaded the bases with no outs in the fourth on a leadoff walk to Chase Headley and consecutive singles by Chris Denorfia and John Baker.
Cameron Maybin then hit a liner right back to Noesi, who caught the ball at the last moment. But on the next pitch, Amarista hit a ball over the head of left fielder Casper Wells that bounced into the stands for a two-run double.
NOTES: Volquez is 3-0 in four career starts against the Mariners. ... Noesi's other start against San Diego was a 1-0 loss on June 13 when he allowed the game's only run on a home run. ... San Diego finished with an 8-7 interleague record, just the third time in 16 years of interleague play that the Padres had a winning record. The other years were 1999 and 2010. ... Denorfia extended his career-best hitting streak to 11 games, the longest by a Padres player this season. ... Padres 1B Yonder Alonso was out of the starting lineup to give his ailing knee a chance to rest. Alonso is also expected to be out of the lineup for Monday's game at Houston. ... Mariners RHP Erasmo Ramirez (0-1, 5.40 ERA) will face Athletics LHP Tommy Milone (7-5, 4.13) when Seattle returns home on Monday night. ... Padres RHP Ross Ohlendorf (1-0, 4.50) matches up against Astros LHP Wandy Rodriguez on Monday night to start a four-game series.
