CHICAGO -- Ryan Ludwick and the Padres rebounded from an extra inning loss with a rare power surge.
Ludwick had three hits, including one of San Digeo's three home runs, and the Padres salvaged a split of a doubleheader and avoided a series sweep by beating the Chicago Cubs 5-4 on Wednesday night.
"The bats came alive," San Diego manager Bud Black said. "It's good to see us bounce back after a loss in the first game."
The Padres came into the day hitting .213 with nine homers, and Ludwick was at .135 with one home run.
Maybin made key plays in both games for the Padres. He made an acrobatic catch in the right-center field gap in the fifth inning of the nightcap, robbing Starlin Castro of what would have been a game-tying extra-base hit.
"That was a big catch, no doubt. Huge part of the win," Black said. "He has a chance to be a really complete player as his career unfolds."
The catch helped Aaron Harang improve to 4-0.
"It was just nice to help Aaron out," Maybin said. "He pitched his butt off and [Denorfia] came up the next inning with a big homer. It was just a total team effort."
San Diego took the lead for good in the second inning on Ludwick's two-run shot. Maybin extended the lead to 3-0 with his homer in the fourth, and Denorfia connected on a solo home run in the fifth.
Harang (4-0) gave up two runs over six innings before turning it over to the bullpen.
Having spent eight seasons with the Cincinnati Reds, Harang knows all too well what it's like to pitch at Wrigley in April.
"I've been here when it's cold, when it's rainy but a combination of both, it's not a fun atmosphere to be in," he said. "But it's part of the game. You just got to roll with the elements."
The opening game was just like many of the games the punchless Padres play at their spacious home ballpark, Petco Field.
The Cubs led 1-0 when starting pitcher Matt Garza left after six innings. He scattered six hits and walked three while striking out nine -- and even scored the Cubs' first run, on a single by Marlon Byrd in the third inning.
Johnson connected in the 11th off Gregerson (0-1), the fifth Padres pitcher. Cubs reliever Jeff Samardzija (1-0) worked two innings for the victory.
After the Padres tied it in the ninth, Mike Adams gave up a two-out single to Fukudome, ending a streak of 28 consecutive batters retired.
