Detroit Tigers manager Jim Leyland has said that Daniel Nava was one of his toughest omissions from the American League All-Star team.

Nava may not be going to New York next week. But the Red Sox appreciate his value more every day.

Nava’s two-out, two-strike single in the 10th inning on Thursday gave the Sox an 8-7 victory against the Seattle Mariners.

Steven Wright pitched 5⅔ innings of scoreless relief for his first major league victory. He allowed three hits, walked two, and struck out three. Koji Uehara got the final three outs for his seventh save.

It was the second time in the four-game series the Sox came back from a 5-1 deficit to win.

The Sox are 4-3 on their West Coast trip after taking three of four from the Mariners. The Sox have won 19 series this season, one fewer than all of last year.

The winning rally started when Ryan Lavarnway drew a walk after a 10-pitch at-bat off Mariners closer Tom Wilhelmsen (0-3). Rookie Brock Holt then bunted pinch runner Jackie Bradley Jr. to second base.

With two outs, the Mariners intentionally walked Jacoby Ellsbury to get to Nava. Wilhelmsen got ahead, 0 and 2. Nava took a pitch then singled up the middle.

Nava has 52 RBIs on the season, tied for third on the team.

Red Sox starter Ryan Dempster had his worse outing in two months. He gave up seven runs (four earned) on nine hits over 3⅓ innings. Dempster walked one and struck out four.

The Mariners called up 23-year-old Erasmo Ramirez from Triple A Tacoma to make the start. Ellsbury started the game by driving Ramirez’s third pitch — a changeup over the middle of the plate — deep into the stands in right field.
