After watching him deliver a successful two-start stint in the minor leagues, the Oakland Athletics recalled right-hander James Kaprielian from Triple-A Las Vegas.
In a corresponding move, right-hander Spencer Patton was designated for assignment.
Kaprielian, 29, made Oakland's Opening Day roster, but he was optioned to Las Vegas on April 25 after he started the season with an 0-2 record in six appearances (three starts) and had a 12.94 ERA in 16 innings.
At Triple-A, Kaprielian was 1-0 with a 1.08 ERA in two starts (8 1/3 innings). In parts of four major league seasons, he is 13-16 with a 4.71 ERA in 58 appearances (50 starts).
Patton, 35, had a 6.75 ERA in four relief appearances for the A's. In six major league seasons, with the Texas Rangers (2014-15, 2021-22), Chicago Cubs (2016) and A's, Patton is 5-4 with a 5.19 ERA in 105 relief appearances.
