The Phillies reinstated Rucker (hand) from the 60-day injured list Friday, Matt Gelb of The Athletic report.
Philadelphia acquired Austin Hays in exchange for Seranthony Dominguez and Cristian Pache earlier Friday, and Rucker will fill the open roster spot. The right-hander was acquired from the Cubs in February but has been sidelined by an arterial vasospasm in his right hand. Rucker posted a 4.91 ERA, 1.44 WHIP and 40:19 K:BB over 40.1 innings for Chicago last season and is now on the cusp of his debut with Philadelphia.
