The Astros are designating first baseman Jon Singleton for assignment, according to an announcement from Singleton’s wife Linzy on social media this afternoon. Additional roster maneuvering will be necessary to replace Singleton on the club’s active roster, but it’s not clear what the corresponding transaction will be at this point.

Singleton, 34 in September, was added to the club’s roster last week alongside Shay Whitcomb in the wake of an injury to third baseman Isaac Paredes last week. Singleton ultimately appeared in just three games for the Astros this year, during which he went 1-for-9 with at the plate with one strikeout and no walks. He began the season in the Mets’ minor league system but signed a minor league deal with Houston back in July. Between those two club’s Triple-A affiliates, Singleton has slashed a solid .224/.373/.451 this year with 16 homers in 306 trips to the plate.

More to come.
