Boston Red Sox slugger David Ortiz begins a rehab assignment with Triple-A Pawtucket on Thursday.
He's scheduled to bat third in the line-up.
Ortiz has been sidelined with heel inflammation this spring after missing much of the second half of last season with a right Achilles tendon injury.
The PawSox open their 2013 season at McCoy Stadium on Thursday.
Players will be honored with a special ring ceremony to celebrate last season's Governor's Cup championship.
