PHOENIX -- Shaun Marcum delivered four pain-free innings and Ryan Braun homered twice for the Brewers, who scored a 5-4 win on Monday in the first of back-to-back games against the Padres to close out their Spring Training schedule.

Will Venable hit a pair of home runs for San Diego, one leading off the game against Marcum and another off reliever Sergio Mitre in the fifth inning, and Brad Hawpe delivered a two-run homer in the fourth.

But those homers were not enough to overcome the Brewers' early lead against Padres starter Anthony Bass. Braun went deep with the bases empty in the first inning and again in the third, and Rickie Weeks also added a solo homer in the third inning, as Milwaukee built a 5-1 lead.

More important for the Brewers were the four innings pitched by Marcum, who had skipped his previous start with a stiff right shoulder. He's penciled in as the No. 2 starter for Milwaukee, a team already down right-hander Zack Greinke (rib,) and left-hander Manny Parra (back), who entered Spring Training as the top backup for the starting rotation.

Marcum allowed three runs on four hits, including two home runs, but walked only one batter and struck out four.

For the Padres, Bass was charged with five earned runs on seven hits in 3 1/3 innings.

Up next for Padres: The Padres play their final Cactus League game at 12:05 p.m. PT on Tuesday against the Brewers, and will start with Aaron Harang, who will pitch the home opener against the Giants on April 5. Harang signed a deal in December to return to his native San Diego. Harang, who spent parts of the last eight seasons with the Reds, pitched at Patrick Henry High and later at San Diego State University. He has allowed four runs over his last three appearances. Look for outfielder Cameron Maybin, who suffered a tight right quad on Thursday, to get a few at-bats to get ready for Opening Day.

Up next for Brewers: Left-hander Randy Wolf will lead the Brewers out of Spring Training when he starts the team's Cactus League finale against the Padres on Tuesday. After previewing the Opening Day batting order on Monday, manager Ron Roenicke expects to play all of his regulars again on Tuesday, albeit only for a handful of innings. That means fans should get a last look at Rickie Weeks, Ryan Braun, Prince Fielder & Co. before Thursday's opener in Cincinnati.
