The Giants have claimed right-hander Andrew Moore off waivers from the Rays, according to Andrew Baggarly of The Athletic (Twitter link). Moore will report to San Francisco’s Double-A affiliate in Richmond. To create a 40-man roster spot for Moore, the Giants have also designated infielder Breyvic Valera for assignment.

Valera’s stint on the Giants’ 40-man roster has come to an end before he appeared in a game with the team, which acquired Valera in January when he was designated by the Orioles. In 24 games at Triple-A this season, Valera has posted a .257/.397/.338 slash line, including an impressive 16-to-10 BB:K ratio. The 27-year-old Valera has made only 86 MLB plate appearances and has produced a .529 OPS across parts of the last two seasons, which he spent with the Cardinals, Dodgers, and Orioles.

Moore has appeared in only 11 games in the Major Leagues — nine starts with the Mariners in 2017 — posting a 5.34 ERA in those games. Triple-A has not treated him well this season, as Moore has conceded 9 home runs in 17 1/3 innings while walking as many batters as he has struck out. Moore, a former second-round selection of the Mariners, was recently DFA’d by the Rays, but will hope to make a home in San Francisco. He is just 24 years old and is not far removed from successful seasons in the minors in 2016 and 2017.
