BALTIMORE -- Seth Smith and Manny Machado hit first-inning home runs off Rick Porcello to back a redemptive pitching performance by Alec Asher and help the Baltimore Orioles beat the Boston Red Sox 3-2 Friday night.
Jonathan Schoop had two hits and scored a run for the Orioles, who have won four of five following a seven-game losing streak.
After hitting four home runs in the series opener Thursday, the Orioles used the long ball to take control against Porcello (3-7), the 2016 Cy Young Award winner. Smith drove a 3-2 pitch into the right-field seats for his third career leadoff homer, and Machado pulled a fastball into the second deck for a 2-0 lead.
Asher (2-3) retired 16 of the first 17 batters he faced and ended up allowing two runs and three hits over 6 1-3 innings. It was his second start since replacing Ubaldo Jimenez in the Baltimore rotation; in his first try, Asher yielded six runs over two innings in loss to Houston on Sunday.
Brad Brach, the third Baltimore reliever, got three straight outs for his 11th save in 14 tries.
Pablo Sandoval homered for the Red Sox, now 4-7 against the Orioles after losing two straight in this four-game series between AL East foes.
Porcello gave up three runs and eight hits in six innings. The right-hander went 22-4 last year but this season has allowed at least eight hits in seven of 12 starts -- including each of the last five.
After Sandoval hit a solo shot in the third inning, Schoop singled and scored on a double by Hyun Soo Kim in the fourth.
The Red Sox chased Asher and closed to 3-2 in the seventh. Xander Bogaerts hit a leadoff double and Jackie Bradley delivered a two-out RBI single off Mychal Givens.
BALTIMORE -- Orioles closer Zach Britton ruptured his right Achilles tendon in offseason training, a significant injury that could cause him to miss part of the 2018 season.
Baltimore executive vice president of baseball operations Dan Duquette on Wednesday confirmed the torn Achilles tendon. It was not immediately clear how long Britton would be out.
In a tweet announcing the injury, the team said Britton was injured Tuesday while training in California and wished him a speedy recovery.
Britton had 15 saves and a 2.89 ERA with the Orioles this past season. In 2016, had a 0.54 ERA and was perfect in save opportunities with a major league-leading 47.
The left-hander, who turns 30 on Friday, is arbitration eligible after making $11.4 million last season. Britton can become a free agent after next season, which made him a strong trade candidate before the injury.
Britton has converted 135 of 145 save opportunities since becoming the Orioles' closer in 2014.
MORE ORIOLES: GAUSMAN CHANGES HIS NUMBER TO HONOR ROY HALLADAY
BALTIMORE -- Orioles pitcher Kevin Gausman will wear No. 34 next season as a tribute to Roy Halladay, who was killed in a plane crash last month.
Gausman announced the switch Thursday on his Twitter account. The right-hander wore No. 39 last year.
Gausman and Halladay are both from Colorado, and the Orioles pitcher said he followed Halladay's career closely and idolized him.
In a post next a photo of his new jersey, Gausman wrote: "Roy gave me the inspiration that I could fulfill even my biggest of dreams -- being a pitcher just like him."
Gausman concluded: "The loss of Roy is tragic and saddening, but I feel honored to have watched everything he achieved."
Halladay died on Nov. 7 when his small plane crashed into the Gulf of Mexico. He played 16 big league seasons, winning the Cy Young Award in each league and being named an All-Star eight times.
