BOSTON -- Jackie Bradley Jr. took advantage of an off day from ace Felix Hernandez.

The right fielder slugged a pair of two-run home runs and had seven RBIs as the Boston Red Sox lit up the Mariners' right-hander for 10 runs in 2 1/3 innings in Saturday's 22-10 rout.

"He still looks like the king," said Bradley, who stroked a franchise-record five extra-base hits, including two off the American League's leader in wins.

"I think everybody's entitled to have an off day. Today was his day."

Bradley (5-for-6) homered off Hernandez in the second inning as the Red Sox posted five-run innings in the second and third and closed the game with 11 runs over the final three frames.

"I wanted to be aggressive with him because he's a pitcher that attacks the zone with all of his pitches," said Bradley, who also added an RBI double in the sixth, a two-run double in the seventh and a home run in the eighth.

Boston (52-64) has 37 runs on 47 hits -- including a season-high 26 hits on Saturday -- in the last two games after scoring 45 runs in the first 10 games of August.

The Red Sox also have at least 15 runs in each of the last two games.

"I wish I knew (why)," interim Red Sox manager Torey Lovullo said. "It's just a bunch of guys going up, having a great approach, not missing their pitch. We were having some really, really loud contact throughout the course of this game, throughout the course of yesterday's game."

Shortstop Xander Bogaerts and catcher Blake Swihart each had four hits for Boston. Designated hitter David Ortiz had three hits and three RBIs.

Bogaerts was one of seven Red Sox batters with at least two RBIs.

Left fielder Alejandro De Aza hit a two-run homer, and third baseman Pablo Sandoval launched a solo shot before leaving the game in the fourth inning -- he had taken a pitch off his right elbow an inning earlier.

Wade Miley (9-9) gave up two runs on four hits and struck out eight in seven innings for Boston.

"The offense was going for me," he said. "They were scoring a lot of runs. I just tried to not give up more than they scored to get them back out there to hit. They can take all the time they want."

Hernandez (14-7) gave up 11 or more hits for the third time in four starts, as the Mariners' right-hander was tagged for 12 hits and three homers in his second-shortest outing of the year.

"That was embarrassing," Hernandez said. "I could not get the ball down. Every pitch I threw, they hit it."

Right fielder Nelson Cruz hit a two-run home run and had three RBIs to lead Seattle (54-63), which has been outscored by 25 runs in the series.

"There's not a lot you can say. We got our butts kicked," Mariners manager Lloyd McClendon said. "The only silver lining in all of this is that we scored 10 runs, the offense came alive and kept battling, and there were no injuries. You just move on and you get ready for the next one."

Mariners center fielder Austin Jackson hit a two-run homer and drove in three runs, while catcher Mike Zunino added a solo shot.

Shortstop Ketel Marte and left fielder Logan Morrison also drove in runs for Seattle.
