"It's pretty contagious right now," said Davis, laughing when he noticed the danger of using that word in a clubhouse that has seen more than a half-dozen players come down with pink eye. "And what better time than with the bases loaded? It feels great."
Davis has logged 10 RBIs during his six-game hitting streak. Ryan Braun doubled home a run in the fourth inning and has a six-game hitting streak of his own. Brewers second baseman Scooter Gennett had three hits, scored two runs and drove in one. Shortstop Jean Segura went 2-for-3 and scored twice.
"I don't care where you're doing it," said Braun, "it's an impressive stretch we've been on."
Luis Jimenez slugged the Brewers' second grand slam of the day in the eighth inning, connecting off Seattle's Mark Lowe.
Brewers starter Mike Fiers made his first Cactus League appearance since March 13 and allowed one run on three hits and a walk in 3 2/3 innings against a Seattle split squad that included Robinson Cano, Austin Jackson and Logan Morrison. The run scored when Davis couldn't come up with a diving catch of Jesus Sucre's run-scoring single in the top of the third inning.
Fiers had been scratched from his previous Cactus League start with right shoulder fatigue. Before Thursday, his last start had come in Minor League camp.
"Great day," Fiers said. "I was really throwing strikes and getting back to where I was. I think I'm pretty much there. It's all about getting the pitch count up now."
Mariners Up Next: Left-hander James Paxton makes his second Cactus League start Friday as the Mariners travel to Surprise to face the Royals in a 6:05 p.m. PT game that will be available on MLB.TV. After dealing with a bruised forearm early in camp, Paxton threw 3 1/3 shutout innings in his debut Sunday against Texas and is in line for one more start next week prior to the start of the season. Dominic Leone and Yoervis Medina are slated to pitch in relief.
