"We get a combination of power and two-out hits all the way up and down the lineup," said catcher Nick Hundley, who hit a three-run homer beyond the left-center-field seats to cap the scoring at 13. "Everybody got involved, so everybody's driving in runs. It's contagious."
It was the fourth time the Padres scored at least eight runs this season, but the first time they eclipsed nine. Each of those games have been wins, and San Diego improved to 7-2 when scoring more than five runs in a game. The Padres' 17 hits were also a season high.
"Tough night to pitch," manager Bud Black said. "Wind blowing out. Conditions favorable for the offense."
Left fielder Carlos Quentin went 3-for-4 with two doubles and a home run, and second baseman Jedd Gyorko and third baseman Chase Headley each chipped in two hits. By the time Chris Denorfia singled in the seventh, every Padres starter had at least one hit.
The Padres scored in four of the first six innings, jumping out to a 2-0 lead in the second when Yonder Alonso and Mark Kotsay both singled and scored on a Gyorko double. Everth Cabrera walked and scored in the third before a fifth-inning rally that featured 10 batters come to the plate.
The Padres, as a team, hit for the cycle -- Cabrera tripled, Headley and Quentin both doubled and Alonso hit a two-run homer -- before starting pitcher Edinson Volquez drove in the eighth run of the game with a single to center, plating Kotsay. That was the end for Cubs starter Edwin Jackson, who lasted just 4 2/3 innings. He gave up 11 hits and fell to 0-4.
"This may be one of the worst starts I've had in my career," Jackson said. "It's a test of character. Clearly, it hasn't been what I wanted to do. It's a long season. I'll definitely continue to work and get back to where I need to be to finish the season strong."
That fifth-inning sequence would prove vital for Volquez, given the way his night spiraled in the following half-inning. Once he was spotted that 8-0 advantage, he surrendered four extra-base hits in the bottom of the fifth, as a pair of two-run homers from Luis Valbuena and Starlin Castro sliced the lead to 8-4.
"I lost a little bit, I was off a little bit. Everything was good. I just lost it," Volquez said of the wall he hit in the fifth. "But it's not a big deal. I can come back tomorrow and try to fix it and do what I was doing before."
Volquez did extend a streak of consecutive innings without a walk to 13 until the sixth inning, when he walked three batters in that frame alone. It was an 11-pitch walk drawn by Darwin Barney that brought Black out to get Volquez.
Dale Thayer came in to end the threat, and he held the Cubs in check as the three-run Hundley home run in the eighth made it 13-5.
"That was one of the better balls I've hit in my career," Hundley said. "For sure."
Rookie left-hander Robbie Erlin made his big league debut, surrendering three hits -- including a Cody Ransom homer -- in a two-run ninth.
Volquez is now 5-0 with a 2.76 ERA in seven career starts against the Cubs, including a 3-0 mark with a 3.63 ERA in four starts at Wrigley Field -- wind blowing out and all.
"Eddy held the fort," Black said. "We gave him some runs. He never gave back the lead. He outpitched their starter, so good job."
