Span, on the disabled list retroactive to Aug. 15 with migraines stemming from a concussion suffered on June 3, began working out at the ballpark on Saturday, but Monday was his first day back with the club, as the Twins were in Anaheim over the weekend.
He said the week at home was much needed and that he plans on working out with the team moving forward, with the hope of playing again this season.
"I do truly believe that I will be back on the field," Span said. "When? I don't know. But I will be back out there. If things go good, I would like to go into the offseason having played in some games here. I'd rather do that than go into the offseason not playing at all."
Span said it's been rough on him since suffering the concussion because he wants to play, but the symptoms have affected his energy level and concentration. He's talked with first baseman Justin Morneau about the injury, as Morneau missed the second half of last year with a concussion and is currently out again with concussion symptoms after diving for a ground ball on Aug. 28.
"It's not a normal injury," Span said. "Sometimes you start wondering if people believe what you're telling them about how you feel. So mentally, it's little things like that. You know how this game is and all masculine sports -- everybody feels that if you're not bleeding, you should go out there and play. And I tried doing that, so it's not like I didn't try. So that's been tough for me."
Morneau, meanwhile, also hopes to play again this year, and when he does, he'll serve only as the designated hitter, according to Twins manager Ron Gardenhire.
"He said he's doing better but isn't ready to play baseball," Gardenhire said. "But when he does, he'll come back, and we're pretty much going to DH [him] for the rest of the season. We don't want to play him in the field to keep him from diving around and not banging himself up."
