9:45am: Highly regarded righty Bryan Abreu will take the open roster spot, per the Astros Future Twitter account (link). The 22-year-old already has a 40-man spot but hadn’t yet debuted in the majors. It could just be a brief fill-in job, but the Astros could also consider Abreu a late-season option at the MLB level. Abreu is said to possess high-end stuff but is still learning how to command it. He is being developed as a starter in the minors. In 55 2/3 innings this year at the Double-A level, Abreu owns a 5.17 ERA with 10.8 K/9 and 5.2 BB/9.
9:28am: The Astros have placed reliever Ryan Pressly on the 10-day injured list, per Chandler Rome of the Houston Chronicle (Twitter link). It seems the move was technically made yesterday, Jake Kaplan of The Athletic notes on Twitter, since it’s backdated to June 27th.
Fortunately, this still seems to be a minor issue for the Houston organization and one of its best arms. Pressly has been limited by knee soreness after being struck in the joint by a batted ball, but there’s no indication he is dealing with any structural issues. With a healthy division lead, the ’Stros can afford to allow Pressly a chance to heal up and get back to full health.
Pressly, 30, has been exceptional again this season after being traded to Houston in the midst of a breakout 2018 showing. (He went on to ink an extension that seems to represent an exceptional value for the club.) Through 44 1/3 innings in 2019, Pressly has produced a 2.03 ERA while carrying 11.2 K/9 against 1.6 BB/9 along with a 50.9% groundball rate.
With or without today’s injury news, the Astros figure to be on the hunt for relief arms. While it’s certainly not the chief need — that’d be in the rotation — the club could stand to improve and deepen its bullpen, particularly from the left side.
