Tim Stauffer, whose drop in velocity on his fastball has mystified Twins coaches, was placed on the disabled list Friday with a right intercostal (rib cage) strain. Ryan Pressly, who was cut after a disappointing spring, was recalled from AAA Rochester.

Stauffer, signed as a free agent over the winter, had an 8.38 ERA in eight appearances with the Twins this season, allowing 16 hits and six walks in 9 2/3 innings. His fastball, which had been in the low 90s with San Diego the past couple seasons, did not consistently crack 90 mph this season.

Pressley was 0-2 with a 4.50 ERA with Rochester after a spring training that saw him post an 8.31 ERA in four appearances. He allowed 10 hits in 4 1/3 innings duriung the spring.

Pressly made 74 relief appearances with the Twins the past two seasons, posting a 3.60 ERA in 105 innings. He'll be in uniform for tonight's game againt the visiting White Sox.
