Seattle's 20 home runs lead all big league clubs, and its eight-game winning streak is the team's longest since winning the final eight games of the Spring Training slate in 1993.
"There is something going on in Spring Training. Everybody is hitting homers," Gutierrez said. "I think it's something contagious when everybody's hitting. Everybody [else] starts hitting too. It's just fun to be around these guys and to see what's going to be the Opening Day lineup."
The Dodgers (3-4-2) scored in the first inning Saturday, when they used singles from Hanley Ramirez and Andre Ethier and a double play to get on the board. Ethier came back in the third inning with a triple off the fence in right-center, and he came around to score on a single by Adrian Gonzalez.
Seattle answered in the third inning on a solo homer by rookie catcher Mike Zunino, and after an error, Gutierrez homered over the left-field fence to tie the game. The Mariners mounted another rally against Chad Billingsley in the fourth inning, and Gutierrez drove home two runs on a double.
Seattle starter Hisashi Iwakuma worked two innings and allowed two hits in the game, and veteran Jeremy Bonderman allowed three hits and two earned runs in two innings of work. Catcher John Hicks broke the game open with a two-run double in the seventh and scored on a wild pitch.
Veteran Chris Capuano started for the Dodgers and retired the game's first six batters before allowing Zunino's home run to lead off the third inning. Billingsley got seven outs for the Dodgers, but he was charged with five hits and three earned runs before leaving in the bottom of the sixth.
Up next for Mariners: Joe Saunders will make his first start of the spring for Seattle on Sunday, and he'll take on Texas in a 12:05 p.m. PT game at Surprise Stadium. Saunders has worked one inning this spring, and he allowed three hits and two earned runs. Hector Noesi is scheduled to throw two relief innings for Seattle, and he'll be followed by Josh Kinney, Carson Smith and Jonathan Arias.
