Valencia will have an extensive workout Thursday at Rogers Centre and doesn't expect any complications.
"I feel a lot better than I did a couple of days ago," Valencia said. "There has definitely been progress. I don't have any of the pain I had before. I'm looking forward to getting back on the field."
Manager Ned Yost will monitor Valencia's workout before deciding how to fill out his lineup card in the four-game set.
"If his hand is fine, there's a big possibility that he'll play," Yost said. "I think -- and it's only what I think -- that he'll play in the Toronto series."
