Weiss delivered two hitless innings in relief in Monday's win over the Red Sox, striking out three while walking one.
Weiss failed to crack Houston's rotation out of spring training, though he did make the team as a bullpen option. The right-hander looked sharp Monday, as he set down six straight Red Sox after issuing a leadoff walk in the eighth. It was an encouraging performance for Weiss, after he gave up a home run to Zach Neto in his major league debut Friday. While Weiss could work his way into the high-leverage picture, he's more likely to serve as a swingman or long-relief option this year.

Astros' Ryan Weiss: Competing for final rotation spot
Rotowire
Weiss delivered 2.1 scoreless innings in Thursday's Grapefruit League matchup with the Mets, allowing a hit and a pair of walks.
It was a solid spring debut overall for Weiss, as he was able to work out of trouble to keep the Mets off the board. The 29-year-old right-hander is competing with Spencer Arrighetti, Lance McCullers and AJ Blubaugh for one of the final two spots in the Astros' six-man rotation. Weiss, who featured a mid-90's fastball paired with three different offspeed pitches, signed a one-year deal with Houston after posting an impressive 2.87 ERA with 207 strikeouts across 178.2 innings in the KBO last year. Weiss figures to start the year as a swingman out of the bullpen, should he fail to crack the Opening Day rotation.

Royals' Ryan Weiss: Claimed by Kansas City
Rotowire
Weiss was claimed off waivers by the Royals on Friday and optioned to Triple-A Omaha.
The Diamondbacks designated Weiss for assignment last weekend, but the Royals deemed him worthy of a 40-man spot. Matt Peacock was DFA'd to make room for Weiss, who has mostly struggled at Triple-A the past two seasons. He will likely need to improve upon his 7.45 ERA at that level this year in order to get a look in Kansas City.
