Salas was added to the 40-man roster Thursday but his time in Philadelphia was short-lived. He made two appearances in his most recent stint with the club, allowing one earned run and five hits across 1.2 innings of work.

Philadelphia already had an existing opening on the 40-man roster, so no corresponding transaction was needed to clear room for Salas. He and Cole Irvin will report to the Philadelphia bullpen, offering the big club a pair of fresh arms after five relievers were needed to cover the final 6.2 innings of Wednesday's 7-2 loss. Two of those relievers -- Austin Davis and Edgar Garcia -- were sent down to Triple-A to open up spots on the active roster for Salas and Irvin.

As anticipated, the well-traveled reliever went unclaimed off waivers after being designated for assignment earlier in the weekend. He'll stick around in the organization as bullpen depth at Triple-A.

Salas had his contract selected by the Phillies on Monday and gave up one run on three hits during his lone appearance. The move was made to make room on the 40-man roster for the return of Tommy Hunter (elbow) from the 60-day injured list.
