"Omar Infante is fine," Leyland said. "His quad was a little tight last night and I'm not going to take any chances, because I want him playing tomorrow against the lefty."
It was a scheduled day off for Hunter, but it will give Don Kelly his second straight start after he homered in Tuesday's game.
Matt Tuiasosopo was in left field, making his sixth start of the season against a right-handed pitcher. Mariners' starter Hisashi Iwakuma has held left-handed batters to a .217 batting average and 10 home runs this season, while righties are batting .235 with 15 home runs.
"[Iwakuma's] split dives away from the left-handers and the split comes in to the right-handers," Leyland said. "That doesn't mean they're going to hit it. He's pretty good; this guy's a very good pitcher. We've got our hands full."
