ST. PETERSBURG, FLA. – The Twins placed righthander J.R. Graham on the 15-day disabled list Wednesday because of right shoulder inflammation after he reported soreness following his outing the night before.
That enabled the Twins to activate Blaine Boyer from the 15-day disabled list after he recovered from a sore left elbow.
Graham gave up one run in two-thirds of an inning Tuesday — enough to get his first major league victory — but his four-seam fastball averaged a season-low 93.9 miles per hour. He has averaged 3-4 more miles per hour in other outings, and the dip in velocity suggested something was wrong.
After a night of sleep, Graham still felt discomfort and alerted team trainers.
"The only thing I noticed as of late was his velocity numbers have been down the last few outings," Twins manager Paul Molitor said. "We really hadn't heard anything as of issues. My thought was that the guy has been a starter [in the minors]. He's been on a different routine this year, having to adapt to something different. He's heading into a September, which he hasn't done before."
The Twins hope Graham will be ready in two to three weeks and contribute down the stretch. A Rule 5 pick in December from the Braves organization, the Twins had to take the good and the bad from Graham. They are required to keep him on the 25-man roster all season or offer him back to Atlanta.
In 34 games, Graham was 1-1 with a 5.15 ERA.
"It's mostly been an upward trend," Molitor said. "There have been games and appearances where it's gone back a bit."
