KANSAS CITY, Mo. (AP) - Jake Peavy's pitch count escalated early and he exited without retiring a batter in the sixth.
Justin Maxwell homered and then singled twice in a six-run sixth as the Kansas City Royals rallied for a 9-6 victory over the Boston Red Sox on Friday night.
Peavy, who threw 58 pitches in the first two innings, took a 6-3 lead into the sixth, but soon after disappeared.
Peavy, who was making his second Red Sox start since acquired in a July 30 trade from the Chicago White Sox, yielded singles to Maxwell, Mike Moustakas and Alcides Escobar to start the inning. Escobar's RBI single finished Peavy.
``I obviously take the blame,' Peavy said. ``You can't blame the offense when they score six runs. I just didn't make a whole lot of consistent pitches.
``I had Maxwell 0-2 and threw him a changeup and he did a nice job (to start the sixth). You've got to win games when your offense scores six. I didn't feel good stuff-wise or control-wise. They battled and put the ball in play for being as free-swinging as they are. My stuff wasn't very sharp.'
The Royals have won 15 of their past 17 games to move seven games above .500, matching their best record of the season.
``You can tell they're playing well and when you play well you have confidence,' Peavy said.
Maxwell, who the Royals acquired on July 31 from the Astros for a minor league pitcher, homered leading off the second.
With the Royals trailing 6-3 in the sixth, he led off the inning with a single. The Royals sent 11 men to the plate in the inning against Peavy, Drake Britton and Pedro Beato.
``With the way Jake had settled in, he had good innings in the fourth and fifth, and we'd gained momentum for ourselves, he probably had one inning left with his pitch count,' Red Sox manager John Farrell said.
``I'm not going to say it was surprising, but he left some balls up and they made him pay. The put away pitch was a challenge for how they put the ball in play and go the other way. We just couldn't stop the momentum in the sixth.'
Eric Hosmer's two-run single with two outs off Britton put the Royals on top 7-6. David Lough contributed a sacrifice fly, while Billy Butler doubled home Hosmer. Maxwell's second single in the inning scored Butler with the final run.
Mike Napoli, a career .368 hitter off Royals right-hander Ervin Santana, cleared the bases with a two-out third inning three-run double.
``He had two hits and a big double and a walk and drove in some runs,' Farrell said of Napoli. ``It was a very good night for him. He got the fastball up against Santana in a key spot.'
Santana left after Napoli's double, allowing six runs on nine hits, including David Ortiz's 22nd home run in the third, in 3 2/3 innings, his shortest outing of the season.
Peavy lasted five innings, plus three batters, allowing six runs on 10 hits.
Francisley Bueno (1-0), who was just promoted Thursday from Triple-A Omaha, picked up the victory with 2 1-3 scoreless innings. He has two big league wins, both against the Red Sox. Britton (1-1) was charged with the loss.
The Royals' 16-hit attack, included three hits each by Butler, Hosmer and Maxwell. Alex Gordon had two hits, including his 12th home run.
Greg Holland worked the ninth for his 31st save in 33 chances.
Notes: Red Sox C David Ross, who has been out since June 18 with a concussion, could start rehabbing with Tuesday with Double-A Portland if he gets the final approval. He has been cleared by Dr. Michael Collins, a concussion specialist in Pittsburgh, and the results were forwarded to Major League Baseball, which has the final word. If all goes well, Ross could be activated Aug. 19, the first day he is eligible. ... Royals All-Star C Salvador Perez is progressing in his on-the-field activities and manager Ned Yost is hopeful he'll get the clearance to play Sunday, the first day he is eligible. ... After an appeal from the Royals, MLB reversed two Mets scorings calls from Sunday, giving Alex Gordon and Lorenzo Cain hits on ``sun balls' that were first called errors.
