PHILADELPHIA -- After hitting a home run and double in his first three at-bats in Tuesday's 10-9 win over the Phillies, Mariners second baseman Robinson Cano was taken out of the game in the bottom of the fourth inning with a strained quadriceps muscle.
Manager Scott Servais said Cano is day-to-day, though it's unlikely he'll be ready to bounce back in time for Wednesday's day game.
"He did it going into second," Servais said. "It's unfortunate, we hope it's not serious. I don't think it is. Maybe a day or two. He may be ready tomorrow. It truly is day-to-day."
Cano hit his seventh homer of the year, a two-run shot in the third to cut an early Phillies lead in half.
He then added a double in the fourth after Seattle had taken a 5-4 lead and felt the quadriceps tighten as he reached second base.
Cano was standing at second as the Phillies made a pitching change and he headed to the dugout during that break in play to get the leg wrapped, but returned to second and remained there as the inning ended. But when the Mariners came out to take the field in the bottom of the fourth, Cano was replaced at second base by utility infielder Taylor Motter.
Motter wound up getting the game-winning hit with his RBI double in the ninth and has hit well in filling in for shortstop Jean Segura and third baseman Kyle Seager earlier this year, but losing Cano obviously for any length of time obviously would be a blow.
Cano is hitting .277 with seven home runs and 25 RBIs in Seattle's first 33 games.
"Hopefully he's better tomorrow," Motter said. "We'll see what happens. Especially with the role I'm in now, I have to be ready whenever I can."
