CC Sabathia has struggled this season and is headed for a historically bad ERA.
The left-hander's 4.90 ERA would be the second-worst for a New York Yankee pitcher that threw at least 200 innings in a season.
Randy Johnson had a 5.00 ERA for the Yankees in 2006.
Sabathia hasn't posted an ERA over 4.00 since the 2005 season with the Cleveland Indians.
