BOSTON -- One of the New York Yankees' newest additions, left-handed pitcher J.A. Happ, went on the 10-day disabled list Thursday (retroactive to Monday) after being diagnosed earlier this week with what general manager Brian Cashman called a "mild" case of hand, foot and mouth disease.
Happ will miss his next start, which was slated to be at Fenway Park on Saturday against the Boston Red Sox. Right-hander Luis Cessa is being called up from Triple-A to replace him. In three big-League starts this season, Cessa is 1-2 with a 3.10 ERA.
