Alcala was recalled from Triple-A Rochester on Saturday.
Alcala was sent to Triple-A on April 21, and he gave up one run in 4.2 innings with six strikeouts and four walks for St. Paul. Alcala had surrendered six runs -- five earned -- on seven hits and five walks through 10 innings of relief. His walk rate was a concern, so his Triple-A stint isn't overly reassuring. He'll return to a middle relief role with the Twins.
