Vasquez (ankle) made his second rehab appearance Wednesday, striking out one over a scoreless inning for Triple-A Buffalo.
Vasquez started up his rehab assignment last weekend in the rookie-level Florida Complex League before moving up to the Blue Jays' top affiliate. The 28-year-old southpaw will likely stick with Buffalo through the weekend before the team decides whether to activate him from the 15-day injured list or extend his minor-league assignment.
