Rodriguez sustained three gashes on his right hand when the Twins' Danny Valencia caught him with his spikes on a stolen-base attempt in the ninth inning of Thursday's 3-2 loss in Minneapolis.
"He got me good," Rodriguez said Friday. "I tried to grip my bat and I can't do it, so I don't know. I'll see how it feels tomorrow."
That leaves Seager as the club's only healthy shortstop, though third baseman Alex Liddi played a few games there this season at Triple-A Tacoma.
Prior to Friday's series opener, Seager had started 38 games this season at third base, four at shortstop and two at second.
"Getting to play the two games at shortstop in Minnesota helped me feel more comfortable," Seager said. "It's a very unfortunate situation with the guys getting hurt, but I do feel more comfortable and I'm ready to go."
Seager's continued motto, no matter where he's been lined up?
"I just want to play," said the 23-year-old.
Wedge figures it's another chance to see what one of his youngsters who might help in the future can do right now. But he also wants to be careful not to pigeonhole Seager as a utility-type infielder.
"I don't want to tag him with that because I think he has the ability to be an everyday player," Wedge said. "The way I look at it, worst-case scenario he should be a utility player. Because he has the ability to hit, he's a good kid and can move around a little bit. And he's still so young."
