Seattle pulled within 4-2 in the bottom half when Mike Carp doubled home one run and Miguel Olivo’s single plated the other.

Howie Kendrick and Hunter had run-scoring singles to drive Vasquez out of the game in the fifth. Jeff Gray walked three straight hitters, including Vernon Wells and Trout with the bases loaded before Erick Aybar hit a two-run single to make it 10-2. Maicer Izturis added a sacrifice fly and Peter Bourjos had a run-scoring single to cap the uprising.

Seattle’s Ichiro Suzuki extended his hitting streak to 13 games with a two-run single in the seventh.
