Webb has been promoted to the majors Thursday prior to the Yankees game against Los Angeles.
The Yankees selected the contract of Webb on Thursday while sending Rob Refsnyder down to Triple-A Scranton/Wilkes-Barre. Throughout the 2017 season in Triple-A, Webb has posted a 3.24 ERA with a 1.09 WHIP to go along with an outstanding 47:3 K:BB in just over 31 innings of work. Webb has yet to appear in a major-league game, but could get his first opportunity in the next few days.
