The Houston Astros have opted not to retain one of their midseason acquisitions from the 2019 campaign.

According to insider Mark Feinsand, the defending AL champs are non-tendering Aaron Sanchez, allowing the veteran hurler to hit the open market.

Sanchez was acquired by the Astros at the trade deadline in a deal with the Toronto Blue Jays. The righty featured in just four games for the Astros before suffering a shoulder injury and undergoing surgery, which is expected to keep him out for the beginning of the 2020 season.

The injury, mixed with less than desirable results on the mound -- despite throwing in a combined no-hitter during his Astros debut -- made the choice a fairly simple one for Jeff Luhnow and Co.

Last season, Sanchez threw 131.1 innings, posting a 5-14 record with an unfavorable 5.89 ERA and 5.25 FIP -- which suggests it wasn't luck working against the 27-year-old. He whiffed 115 batters and recorded an uninspiring 1.622 WHIP.

Sanchez, who was an All-Star in 2016, has since failed to replicate that stellar season that saw him go 15-2 with a 3.00 ERA across 30 starts. He'll now hit free agency, though his injury may be a cause for concern from some organizations in the market for a starting pitcher.
