CHICAGO -- Todd Hollandsworth feels he gets more comfortable at the plate as the game goes on.
"Honestly, for some reason I'm probably more nervous when the game starts than in the situation there," Hollandsworth said. "For some reason, I seem to relax, just really bear down and focus."
Jeromy Burnitz hit a triple off the left-center field wall with one out in the 12th against Derrick Turnbow (0-1), the sixth Milwaukee pitcher. After an intentional walk to Derrek Lee, Hollandsworth delivered.
"(The pitch) was down and away and he just slapped it over and through the hole," Turnbow said. "It just happens sometimes."
Reliever Glendon Rusch (2-0) pitched three scoreless innings to earn the win. He allowed three hits and struck out four.
"I was in a jam every inning today it seemed like," Rusch said. "It was great to weasel my way out of all of them and give us a chance to win."
The Cubs scored three runs off Milwaukee reliever Tommy Phelps to tie it at 5 in the sixth inning. Phelps gave up hits to the first three batters of the inning, and was removed after Hollandsworth hit a run-scoring single.
Ricky Bottalico relieved and hit Michael Barrett to load the bases, and the Cubs then scored two runs on a groundout and an infield single.
The runs were the first allowed by the Brewers' bullpen this year after 12 2/3 scoreless innings.
Bottalico, Matt Wise and Jorge De La Rosa didn't allow a run in five innings Sunday.
"Our bullpen did a great job today," Brewers manager Ned Yost said. "Ricky Bottalico, Matt Wise and Jorge De La Rosa were all very good. "(Phelps) just didn't have it today."
Chicago starter Greg Maddux allowed four runs -- three earned -- and nine hits, including two homers, in five innings. The Cubs right-hander entered the game 10-2 with a 1.45 ERA against the Brewers, but Milwaukee touched him for single runs in four of the first five innings.
"It could have been worse I guess," Maddux said. "I'm not happy pitching only five innings, but if you pitch better you get to stay in longer."
Chicago's Aramis Ramirez had three doubles and an RBI. Burnitz, Neifi Perez and Corey Patterson also drove in runs for the Cubs.
Milwaukee's Junior Spivey, Lyle Overbay and Damian Miller each hit solo home runs. Spivey and Miller each added two singles.
Brewers starter Victor Santos pitched five strong innings, allowing two runs on three hits.
De La Rosa struck out five in the ninth and 10th innings. ... Cubs RHP Mark Prior threw 30 pitches from the Wrigley Field mound before the game. The Cubs will announce on Monday whether he starts at home against San Diego or in the minors on Tuesday. ... Cubs SS Nomar Garciaparra went 0-for-5 and has just four hits - all singles - in his first 28 at-bats. ... Santos hadn't pitched since April 2 in the Brewer's final preseason game, at Miller Park. He allowed one run in six innings against the White Sox. ... Cubs 2B Todd Walker left the game in the 11th with a sprained knee and will have an MRI. Milwaukee's Carlos Lee took him out at second with a slide in the 10th.
