The Arizona Diamondbacks placed ace Corbin Burnes on the 15-day injured list on Tuesday with right elbow inflammation.
The move is retroactive to Monday for Burnes, who left Sunday’s start against Washington in the fifth inning.
Burnes allowed a run on four hits in 4 2/3 innings against the Nationals before experiencing discomfort and gesturing for help.
The former Cy Young Award winner is 3-2 with a 2.66 ERA through 11 starts during his first season with Arizona.
The Diamondbacks signed Burnes, 30, to a six-year, $210 million contract in free agency in December.
The four-time All-Star is 63-38 with a 3.15 ERA in 210 career games (149 starts) with the Milwaukee Brewers (2018-23), Baltimore Orioles (2024) and Diamondbacks.
Arizona recalled left-hander Tommy Henry from Triple-A Reno in a corresponding move. Henry, 27, appeared in one game for the Diamondbacks on May 5 and allowed one hit in 2 2/3 scoreless innings against the New York Mets.
