Astros' Christian Roa: Takes loss in relief
Rotowire
Roa (0-1) was tagged with the loss in relief Thursday against the Rockies, allowing a run on three hits across 1.1 innings.
Roa has made three straight multi-inning appearances out of the Astros bullpen, but the results have been far from encouraging. Over 5.2 innings, the right-hander has given up four earned runs on seven hits with a 4:3 BB:K while also hitting three batters. Roa owns a 4.91 ERA and 1.91 WHIP in five appearances and 7.1 innings since being recalled from Triple-A Sugar Land, and he could be returned to the minors soon as the Astros continue to try and patch together their staff in the wake of an injury epidemic.

Marlins' Christian Roa: Brought back up to big club
Rotowire
Miami recalled Roa from Triple-A Jacksonville on Saturday.
Roa's return to the Marlins was spurred by fellow reliever Tyler Phillips landing on the paternity list. Phillips is allowed up to three days away from the team, so Roa's time with the big-league squad may be short. Roa has just one appearance with Miami this year, allowing one hit and one walk with three strikeouts over two scoreless innings against Philadelphia on Sept. 6.

Rotowire
The Reds selected Roa to their 40-man roster Tuesday.
Putting Roa on the 40-man roster prevents him from being scooped up by another team in next month's Rule 5 Draft. However, the 24-year-old righty will likely need to show significant improvement before getting the call to the majors after posting a 5.43 ERA and 1.77 WHIP across 61.1 frames with Triple-A Louisville in 2023.
