Just over a year ago, Payton Tolle toured Fenway Park as one of the Red Sox’ newest draftees. The Red Sox will promote Tolle to Triple-A Worcester for this week’s series against Buffalo, a source confirmed Monday. The plan is for Tolle to continue to start games there, but there’s a chance he could emerge as a bullpen option for the big league club down the stretch. Tolle, 22, was the 50th overall pick out of TCU last summer and signed with the Red Sox for a $2 million bonus.
