New York also optioned pitcher Ronald Herrera to Double-A Trenton and recalled pitchers Luis Cessa and Domingo German from Triple-A.
Sabathia, 36, suffered the hamstring injury Tuesday in a start against the Los Angeles Angels, per Max Wildstein of Scout, and hasn't been as durable in recent years as he was for most of his career. The southpaw notched at least 200 innings seven seasons in a row from 2007 to 2013, but he tallied just 46 innings in 2014 and hasn't reached the 200-inning mark since 2013.
Sabathia, one of the best pitchers of his generation, is a six-time All-Star and won the 2007 American League Cy Young with the Cleveland Indians thanks to a 3.21 ERA, 1.14 WHIP and 209 strikeouts in 241 innings.
He also captured the 2009 American League Championship Series MVP for the eventual World Series champion Yankees and has a 3.46 ERA and 1.25 WHIP this year in 75.1 innings.
Although expected ace Masahiro Tanaka has struggled this season, Michael Pineda and Luis Severino have been excellent for the 38-26 Bronx Bombers, especially Severino.
Regular closer Aroldis Chapman has been out since May 12 with left rotator cuff inflammation, and super setup man Dellin Betances has thrived in his stead, registering a microscopic 0.42 ERA and 1.06 WHIP in 21.2 innings. Chapman is expected back this weekend, according to manager Joe Girardi.
Sabathia, who makes $25 million this season, is in the last year of his contract.
