Duffy (Achilles) will make another rehab appearance for Triple-A Durham on Wednesday, Marc Topkin of the Tampa Bay Times reports.
The newly-acquired shortstop went 2-for-3 with a walk in his second appearance for Durham on Tuesday, following a 3-for-6 showing over two games with High-A Charlotte last Thursday and Friday. Duffy's ascension to the big league club appears imminent, with Wednesday's contest potentially serving as his final one in the minors before a call-up.
