Miller, 28, has pitched in parts of three big league campaigns. While he only has 31 career innings, he has gotten to the highest level with five different teams. The righty pitched for three clubs in 2023 alone, logging time with the Brewers, Mets and Dodgers. He allowed eight runs over 15 1/3 major league innings between the trio.
A former fourth-round selection, Miller has allowed nearly seven earned runs per nine in the big leagues. While that’s clearly not ideal, he’s coming off a solid run in Triple-A. Miller worked to a 3.50 ERA through 43 2/3 innings at the top minor league level. He struck out nearly 28% of opponents against an average 8.3% walk percentage.
Miller has exhausted his option years. If he cracks the Seattle roster at any point, he’d need to hold his place on the major league club or be put back on waivers. Despite that, the Triple-A results make him a solid depth addition. The Mariners have one of the game’s best bullpens. They finished fourth in the majors in ERA (3.48) and second in strikeout percentage (26.1%) this year.
