San Francisco Giants right-hander Johnny Cueto was placed on the 10-day disabled list because of a right elbow sprain, the team announced Monday before its game against the San Diego Padres. In addition to moving Cueto to the DL in a transaction retroactive to Sunday, the Giants also put corner infielder Pablo Sandoval on the 10-day disabled list due to a strained right hamstring. In corresponding moves, San Francisco activated second baseman Joe Panik from the disabled list and recalled infielder Kelby Tomlinson from Triple-A Sacramento.
