CHICAGO -- Along with the rain and lightning, the Chicago Cubs unleashed a few big strikes of the their own against Padres starter Chris Young.

Young allowed a career-high four home runs as the Cubs rallied for a 6-4 rain-shortened win over the Padres on Wednesday night. Alfonso Soriano hit his 53rd career leadoff homer, Ryan Theriot connected twice and Geovany Soto went deep as the Cubs overcame an early 2-0 deficit to send the Padres to their 18th loss in 22 games and 10th straight on the road. The Padres are also likely to lose Luis Rodriguez to the disabled list, after the shortstop twisted his left ankle.

Soriano moved into a tie for second place on the all-time list with Craig Biggio in a game that was stopped following a 58-minute delay before the bottom of the eighth after a barrage of lightning and rain. It also started 37 minutes late and was interrupted for four minutes after the fifth inning, but on this humid night, long drives were as constant as the raindrops.

"I was just off," Young said. "Mechanically I wasn't very good. I had trouble finding my rhythm and against a lineup like that, it's hard to come out and not have your best stuff because it's a good lineup and they punish some bad pitches."

Chicago had plenty to smile about even though Adrian Gonzalez hit two homers off Ted Lilly (5-2), giving him 13 overall and at least one in three straight games. His two-run shot in the first put the Padres ahead 2-0, but the Cubs responded with three solo homers in the bottom half against Young (2-2).

That was enough for Lilly, who settled down and won his third straight start. The veteran left-hander allowed three runs and eight hits with seven strikeouts and no walks before leaving to cheers with one out in the seventh.

"Maybe because my pitches are so good they want to swing at the ball," Lilly said about the lack of walks. "I still feel like my command on both sides of the plate can improve."

Carlos Marmol earned his third save in five chances despite allowing a run in the eighth.

Padres manager Bud Black was upset that the game got stopped but also said it's "a tough call" and he respects crew chief Tim Welke "immensely."

More unsettling was the performance by Young, who allowed six runs in four innings and is 0-2 in his last six outings. That left Padres starters 0-11 since Jake Peavy beat the New York Mets on April 16, and right from the start, there was trouble.

Things worsened when the Padres lost Rodriguez. He was injured rounding first following a single in the seventh and was lifted for a pinch runner. The team already lost backup shortstop Everth Cabrera when he broke his hamate bone in Philadelphia last month. Cabrera was placed on the 60-day DL and is out until late June. That leaves backup Chris Burke, whom the team acquired from Seattle in the wake of Cabrera's injury, as the most experienced shortstop on the Padres' roster.

Hitting in the seventh spot, Brian Giles went 1-for-3 with a walk to raise his average to .165. Normally the Padres' No. 3 hitter, Giles hit seventh or lower for the first time since he did so as a member of the Cleveland Indians on Sept. 27, 1998.

"(Giles) is the one guy -- well, I don't want to single him out -- but for us to get it going offensively, we need our entire lineup to get back to their level, to get back to their norm," Black told MLB.com. "… Brian's pressing a little bit. A lot of time you become impatient because of an anxiousness to get out of a fun. You want it to happen yesterday. It's tough."
