The Astros announced to reporters, including Chandler Rome of The Athletic, that Joey Loperfido has been officially added to the roster. His imminent promotion was reported over the weekend. In corresponding moves, the club placed infielder Grae Kessinger on the 10-day injured list due to right shoulder discomfort and designated right-hander Joel Kuhnel for assignment.
Kuhnel, 29, was acquired from the Reds in a cash deal in June of last year. He was designated for assignment in the offseason and eventually elected free agency, but returned to the Astros on a minor league deal and was selected back to the roster a few weeks ago. He made just one appearance, allowing four earned runs in two innings, before being optioned to Triple-A Sugar Land.
He currently has a 6.30 earned run average in 85 2/3 innings at the major league level. His 19% strikeout rate is below average but his 6.3% walk rate and 52.2% ground ball rate are both quite strong. He’s been in decent form in Triple-A this year, with a 3.18 ERA in 11 1/3 innings, despite pitching in the hitter-friendly Pacific Coast League.
The Astros will now have a week to trade Kuhnel or try to pass him through waivers. He still has an option and could therefore be kept in the minors by any club willing to give him a 40-man roster spot. If he were to pass through waivers unclaimed, he would have the right to elect free agency as a player with a previous career outright.
