BOSTON (AP) — Jacoby Ellsbury continued his July power surge with his seventh home run of the month and John Lackey picked up his third consecutive win as the Boston Red Sox extended Seattle's losing streak to 13 with a 7-4 win over the tumbling Mariners on Friday night.

Seattle is one loss away from tying the franchise record for consecutive losses, which was set in September 1992.

Seattle hasn't won since July 5 and is just 6-21 since the Mariners improved to 37-35 and were a half-game out of first place on June 19.

Felix Hernandez (8-9) pitched strongly through six innings, but unraveled in the seventh as the Red Sox added five runs to break open the game.

Lackey (8-8) only had a one-run lead until Boston's big seventh inning.
