Williams was recalled from Triple-A San Antonio on Monday, Robert Murray of The Athletic reports.
Williams earned his first promotion to the majors by posting a combined 2.21 ERA, 1.16 WHIP and 82:30 K:BB in 57 innings between San Antonio and Double-A Biloxi. He'll replace Aaron Wilkerson, who was sent to Triple-A on Monday, on the roster and in the bullpen.
