BOSTON -- Mookie Betts hit a go-ahead home run leading off the seventh inning and pitcher David Price turned in an ace's performance in the Boston Red Sox's 2-1 victory against the Seattle Mariners at Fenway Park on Sunday.

The Red Sox (39-29) took two out of three from the Mariners (36-33), who are now 2-4 on their road trip with four more away games coming up this week against Detroit.

Betts, who was 3-for-5, hit an Edwin Diaz fastball into the Monster Seats to put Boston ahead 2-1. It was Betts' 15th home run of the season.

Price (8-4) matched a season high with eight hits allowed in his 110-pitch outing, but the Mariners couldn't bunch enough hits together to score more than once against him. Price went eight innings, struck out seven and walked none to snap a personal three-game losing streak.

Franklin Gutierrez homered for the third time in three games for the Mariners' lone run.

Seattle starting pitcher Taijuan Walker, who left his prior start June 14 in the fourth inning because of a strained tendon in his right foot, threw five shutout innings with six hits and one walk allowed and three strikeouts. He came out after 88 pitches.

Walker got off to a shaky start and threw 46 pitches in the first two innings. But he kept the Sox off the scoreboard despite allowing three hits and one walk.

Gutierrez led off the fourth inning by homering off Price on a 3-2 changeup for a 1-0 Seattle lead. It was Gutierrez's first hit in five career at-bats against Price.

From there Walker settled down and allowed just three more hits and recorded his first 1-2-3 inning in the fifth inning before he was replaced by reliever Vidal Nuno to start the bottom of the sixth.

Xander Bogaerts and David Ortiz greeted Nuno with consecutive singles to set up first and third with no one out, and Hanley Ramirez's fielder's choice grounder plated Bogaerts to tie the score 1-1. Nuno picked off Ramirez but hit Jackie Bradley Jr. with a pitch and was replaced by Diaz (0-1), who allowed a single to Chris Young and a walk to Travis Shaw to load the bases. Ketel Marte snagged Christian Vazquez's line drive to shortstop to end the rally with the score still tied.

NOTES: The Mariners are optimistic RHP Felix Hernandez, who has been on the 15-day DL since June 1 (retroactive to May 28) with a strained right calf, could start the next step in his attempt to return. Manager Scott Servais said before the game that Hernandez (4-4, 2.86 ERA) will try to play catch on Tuesday or Wednesday. ... Mariners LHP Wade Miley is feeling better, according to Servais, and should be available to return to the starting rotation when he is eligible June 28. Miley went on the DL with a left shoulder impingement Friday. ... Servais confirmed that RHP Adrian Sampson will make a second start, probably Thursday in Detroit. Sampson made his MLB debut against Boston on Saturday and allowed four runs on eight hits in 4 2/3 innings in a 6-2 loss. ... Red Sox manager John Farrell said OF Brock Holt, on the DL since May 20 with a concussion, has had "three good days." Holt was being re-examined Sunday by Dr. Micky Collins.
