BOSTON – Tim Wakefield had his picture taken with the Stanley Cup, then was able to sit back for a while and watch his teammates grab a big early lead.

Kevin Youkilis hit a three-run homer to highlight Boston’s six-run first inning, and Wakefield held Milwaukee to three hits over eight innings, carrying the Red Sox to a 12-3 win over the Brewers on Sunday.

“I’ve always said, ‘If the offense scores that many runs it makes my job a lot easier knowing I can make one or two mistakes,’ ” the 44-year old Wakefield said after enjoying a pregame clubhouse visit by the Stanley Cup champion Bruins before the Red Sox honored them with an on-field ceremony.

“I had my picture taken with the Cup,” Wakefield said, smiling. “I wasn’t touching it. It’s theirs.”

A few minutes after the Red Sox honored the Bruins, they turned Fenway into a TD Garden atmosphere during their six-run first inning, blaring a loud fog horn and playing the same music that’s played down at the other end of the city when the hockey team scores.

Members of the Bruins, who captured the Cup with a Game 7 win over Vancouver on Wednesday, rode in on four Duck Boats — as they did in a parade through the street of Boston on Saturday.

As they entered, Bruins players, most dressed in their black jerseys, threw soft baseballs and pucks to the fans.

Red Sox employees were waving Bruins flags with players names and numbers on them in a ring around the upper seating.

After the boats circled the warning track, the players walked in from center behind captain Zdeno Chara, who carried the Cup most of the way, before they all took part in a ceremonial first pitch.

Wakefield then went out and retired the Brewers on 12 pitches — 11 strikes — before his teammates took control in the first.

“Youk with the big hit, but we kept going,” Red Sox Manager Terry Francona said.

Jacoby Ellsbury and Pedroia opened the first with singles and advanced on a wild pitch before Adrian Gonzalez reached on starter Yovani Gallardo’s fielding error when he dropped first baseman Fielder’s toss covering the bag.

Ellsbury scored on the play. Youkilis then followed with his homer into the seats above the Green Monster, making it 4-0.

David Ortiz and J.D. Drew followed with singles, and Josh Reddick walked with two outs, loading the bases for Ellsbury’s ground-rule double that made it 6-0.

“It felt great,” Ortiz said of the Bruins’ pregame visit. “You don’t get to see a trophy like that every day.”

Dustin Pedroia had a solo homer and drove in two runs, and Marco Scutaro hit a two-run shot for the Red Sox, who won their 13th in 15 games.

Nyjer Morgan and Prince Fielder homered for Milwaukee, which dropped two of three games at Fenway Park this weekend and has lost five of seven overall since winning eight of 10.

Wakefield (4-2) only gave up Casey McGehee’s second-inning double besides the two homers in posting his 183rd career win with the Red Sox. He struck out six and walked one.

“He threw a lot of strikes,” Francona said. “His ball was moving.”

Gallardo (8-4) was tagged for eight runs — five earned — on nine hits, walked two and struck out four in three-plus innings. The right-hander had allowed two runs or fewer in seven of his last eight starts.

And it didn’t get any better for him after the first.

Milwaukee cut it to 6-2 on Morgan’s two-run homer in the top of the second, but Boston broke it open with two in fourth, one in the fifth and two in the sixth.

The Red Sox chased him in the fourth.

In the fourth, Pedroia homered leading off and Gonzalez tripled for his 1,000th career hit. Gonzalez scored on Ortiz’s ground out, making it 8-2.

Pedroia also had a sacrifice fly in the fifth. Scutaro’s two-run homer off Sergio Mitre made it 11-2 in the sixth.

Fielder homered into the right-field seats in the seventh. Gonzalez had an RBI single in the bottom half.
