Jenks begins throwing in first step back

While the Red Sox prepared to place their second starter on the disabled list this week, their bullpen is seemingly on the mend.

Right-hander Bobby Jenks, who has been on the DL since May 5 because of a right biceps strain, played catch from 60 feet Tuesday. It was his first such session since being shut down. All went well and he is expected to increase the distance Wednesday. Jenks likely will need a rehab stint.

Fellow reliever Dan Wheeler (calf) is eligible to come off the disabled list on Friday. He has been on a rehab assignment in Pawtucket.

The Sox are expected to add Michael Bowden to the 'pen on Wednesday when they place Daisuke Matsuzaka on the DL. Matsuzaka will join John Lackey on the shelf. Bowden likely will be sent back to Pawtucket when Wheeler is ready.

One more injury update: Infielder Marco Scutaro (left oblique) still hasn’t been cleared to swing a bat and he won’t be until he is pain free, manager Terry Francona said Tuesday.
