Alvarez (personal) will rejoin the Phillies on Friday and is expected to be activated from the restricted list Sunday, Matt Gelb of The Athletic reports.
Alvarado is slated to do some throwing Saturday and then will be available out of the bullpen again beginning Sunday. The left-handed reliever has been away from the club this week while dealing with a personal matter, and those off-field concerns could help explain his 4.66 ERA, 1.86 WHIP and 7:8 K:BB through 9.2 innings in August.
