SAFECO FIELD - Hisashi Iwakuma is officially struggling.

Iwakuma allowed four or more runs for his fifth consecutive start and three more home runs to the Boston Red Sox as the Seattle Mariners were unable to hold on to an early 5-1 lead. Boston outscored Seattle 5-1 after the third inning to take an 11-8 victory over the Mariners.

Kendrys Morales hit a two-run home run in the first inning to give Seattle the early lead. David Ortiz followed with a solo shot in the second to get Boston on the board before Seattle extended their lead. Brad Miller hit a bases loaded double to clear the bases and score three to give the Mariners a 5-1 cushion.

Then Iwakuma fell apart. Boston came through with five consecutive hits. Dustin Pedroia and Mike Napoli each hit two-run home runs to even the game at 5-5. Brock Holt then drove home Jarrod Saltalamacchia with a sacrifice fly to take the lead.

Morales homered again in the third to draw even and Kyle Seager scored on a triple from Michael Saunders to take a 7-6 lead through three innings.

Blake Beavan replaced Iwakuma and hit Daniel Nava and walked Shane Victorino. Pedroia singled to drive home another run and even the game yet again.

Jackie Bradley Jr. homered to put the Red Sox on top in the fifth inning and Boston scored three more in the eighth to take control and sink the Mariners.

Turning Point: After the Mariners had surged to a 5-1 lead through two innings, Iwakuma allowed five consecutive hits with two home runs and two doubles as the Red Sox rallied to take a 6-5 lead. Seattle's offense then failed to keep up with Boston after both teams drove the starters from the ball game.

Player Of The Game: David Ortiz earns player of the night honors with a 4 for 5 performance with a home run, two doubles and a stolen base. For the Mariners, Brad Miller takes top billing as he drove in four runs with a 3 for 5 night with two doubles at the plate.

Next Up: The third game of this four-game set with the Boston Red Sox takes place Wednesday night as RHP Aaron Harang (4-7, 4.92 ERA) will take on LHP Felix Doubront (5-3, 4.11 ERA).
