Pivetta was recalled from Triple-A Lehigh Valley ahead of his scheduled start Monday against the Braves.
The Phillies' recent decision to demote Zach Eflin to Triple-A coupled with Vince Velasquez's (elbow) placement on the disabled list will open a rotation spot back up for Pivetta, who made four starts with the big club earlier this season. Pivetta accrued an underwhelming 5.12 ERA and 1.81 WHIP over 19.1 innings, but his 21 strikeouts over that span seemingly give him a whiff of upside. He'll line up for two starts this week in his return to the Phillies, with his second turn expected to come Saturday in St. Louis.
