BOSTON >> Rick Porcello pitched seven strong innings to remain unbeaten in his Fenway Park starts this season, Xander Bogaerts homered and the Boston Red Sox sent the Tampa Bay Rays to their fifth straight loss, 4-1 on Saturday.
On a day the Red Sox learned they lost closer Craig Kimbrel with a left knee injury for likely three to six weeks, they won for the fifth time in six games.
Dustin Pedroia added a two-run single for Boston, which looks for a sweep of the three-game series Sunday when former Rays ace David Price is scheduled to pitch.
Brad Miller hit a solo homer for the Rays, who have dropped 21 of 24.
Porcello (11-2) allowed a run on six hits, striking out five and not walking anyone. He's 8-0 in nine Fenway starts.
Koji Uehara worked the ninth for his fourth save, second in two days.
Matt Moore (5-6) gave up four runs, two of them unearned, in six innings. He held the Red Sox scoreless on three hits over seven innings in his last start against them, at home on June 29.
Bogaerts' two-run homer completely left Fenway over the Green Monster seats and made it 2-1 in the fourth. Pedroia's single came an inning later.
Miller's drive gave Tampa Bay a 1-0 lead in the first. He has three career hits against Porcello, all solo homers.
The Red Sox replaced Kimbrel quickly, acquiring Diamondbacks closer Brad Ziegler early Saturday. He's expected to be with the team Sunday.
Kimbrel tore his medial meniscus shagging balls in the outfield Friday and is scheduled for surgery Monday.
The 100-year-old daughter of Babe Ruth — Julia Ruth Stevens — tossed out the ceremonial first pitch. She turned 100 on Thursday.
Rays: CF Kevin Kiermaier (fractured left hand) worked out pregame. Manager Kevin Cash said he'll likely start a rehab assignment Monday and they hope to have him in the lineup Friday.
Red Sox: Manager John Farrell said Brock Holt, who left Friday's game with a sprained left ankle, isn't likely to play Sunday, but the team hopes to have him back Friday. . Farrell also said 1B Hanley Ramirez was "sore." Ramirez was out of the lineup after fouling a ball off his left shin twice in the last few days.
Rays: RHP Jake Odorizzi (3-4, 4.33 ERA) is set to start the series finale on Sunday. He's looking to rebound from a rough start Tuesday when he gave up a season-high seven runs.
Red Sox: Price (8-6, 4.64) looks to snap a personal two-game losing streak. The lefty lost to his former team on June 29, giving up four runs in 6 1/3 innings.
