Reyes had to deal with some visa issues, and he got that straightened away on Thursday in Mexico. Righty Alfredo Aceves had to leave camp for the same reason, and he got his visa along with Reyes. Both players will participate in the team's workout on Friday.
While Aceves has had a pretty normal camp, Reyes will be off to a late start.
"We'll see," said manager Terry Francona. "We haven't seen him. The hope would be he's been throwing a lot. Certainly not being in camp is not an advantage, but we'll have to gauge where he is and how quickly he can get into it. And we'll have a little better feel as we see him in the next couple of days throwing."
Reyes could wind up being a nice find for the Red Sox. The veteran has posted a 3.99 ERA or lower in each of the last five seasons. Last year, he was 3-1 with a 3.55 ERA in 59 appearances with the Cardinals.
