The Phillies plan to reinstate Keller (forearm) from the 15-day injured list Wednesday, Todd Zolecki of MLB.com reports.
Keller made two rehab appearances with Triple-A Lehigh Valley over the weekend, and the Phillies will give him two days to rest up before activating him from the IL. The right-hander has recoded three saves and 13 holds with a 4.15 ERA, 1.35 WHIP and 31:12 K:BB across 30.1 innings this year.
