The Miami Marlins made two major roster moves Sunday, placing outfielder Emilio Bonifacio on the 15-day disabled with a sprained left thumb and optioning first baseman Gaby Sanchez to Class AAA New Orleans. Bonifacio, who leads the major leagues with 20 stolen bases, hurt the thumb getting picked off first base Friday. It was the first time he had been caught stealing this season. Sanchez was the Marlins' lone All-Star Game participant last year. However, this season he has struggled, batting .197 with one home run and 11 RBIs. Also, second baseman Omar Infante left the team to fly to his grandfather's funeral. He is expected to be placed on the bereavement list.
