OAKLAND, Calif. — Manager Bob Melvin recalls when the Athletics had a potent batting order like the one from Boston that keeps beating up on his club.

Once again, Oakland didn’t have the pitching or the offense to compete with the powerful Red Sox.

“Teams that take a lot of pitches and make you throw a lot of pitches, it’s like a boxer, it’s just body blows and body blows and then they give you a good one,” Melvin said. “That’s what they do.”

Rick Porcello didn’t allow a baserunner until Jake Smolinski’s one-out double in the sixth on the way to his majors-leading 19th victory, and Boston routed the A’s yet again with an 11-2 victory Saturday night. The ace right-hander also became the first Red Sox pitcher with 19 wins in his first 22 decisions.

David Ortiz hit a two-run double to highlight Boston’s seven-run third to chants of “Pa-pi! Pa-pi!” for the retiring slugger in his last visit to Oakland.

The early hitting by Boston made for a short day by right-hander Daniel Mengden (1-6), called up from Triple-A Nashville only to allow seven runs and eight hits in just 2 2/3 innings.

“I was just falling behind a little too much. You never want to give a team like that good counts and places to do damage,” he said.

Yoan Moncada had a run-scoring double for his first career hit and RBI — and got the ball as a souvenir. He earned his first start a day after the star Cuban prospect made his major league debut in a 16-2 win.

“It’s a big step getting the first hit,” Moncada said.

Hanley Ramirez added a home run in the third, his fourth in seven games.

Porcello (19-3) gave up four hits and two runs in seven innings, struck out two and didn’t walk a batter. Boston improved to 21-7 in Porcello’s starts and 13-2 in his last 15. The Red Sox scored 11 or more runs against the A’s in their fifth straight, a night after matching their season high with 16 runs.

Mookie Betts hit a two-run double in the first following Ortiz’s first double that moved Dustin Pedroia to third. Betts joined Ted Williams as the only Red Sox with at least 30 home runs with 100 or more RBIs in a season before turning 24.

Ortiz had three more hits and is 5 for 6 with five RBIs this series. He moved within one RBI of the AL lead behind Toronto’s Edwin Encarnacion (108). Ortiz also needs to drive in one more run to tie Dave Winfield for most RBIs by a player 40 or older. A 12-time All-Star and Hall of Famer, Winfield drove in 108 runs for Toronto in 1992.

CANSECO BOBBLEHEAD

How’d Jose Canseco like his bobblehead, handed out Saturday?

“It’s pretty good, it’s pretty accurate. It looks like the pre-Steroid-era bobblehead, though,” he said. “It’s got me kind of skinny. If it would have been the Steroid-era it would have me more beefed up. It looks more like the ’86 bobblehead.”

Of his ceremonial first pitch, Canseco took to Twitter:

“Went with the knuckle .it danced,” he wrote.

TRAINER’S ROOM

Athletics: C Josh Phegley is being shut down for the season because of inflammation in his right knee that landed him in the hospital last weekend. He also dealt with strep throat and manager Bob Melvin said he’s unsure whether that could have triggered further trouble with the knee. … RHP Sonny Gray threw from 105 feet as he tries to work back from a strained right forearm before the end of the season. Until he throws off a mound, it’s unclear whether he will pitch again in 2016.

UP NEXT

Red Sox: LHP Eduardo Rodriguez (2-6, 5.35 ERA) has allowed three or fewer runs in seven of his eight outings since the All-Star break and has a 3.22 ERA with 40 strikeouts to 16 walks.

Athletics: RHP Kendall Graveman (10-9, 3.96) seeks his first career decision against the Red Sox in his third appearance. After beginning 1-6 over his initial nine starts, Graveman is 9-3 with a 3.36 ERA in his last 17.
