SAN FRANCISCO -- The Giants officially added right-hander Sam Dyson to the 25-man roster Friday, prompting them to option utility man Orlando Calixte to Triple-A Sacramento to clear roster room.
San Francisco acquired Dyson from Texas on Tuesday for a player to be named later. Dyson will wear No. 49. Texas designated him for assignment on June 2 after he went 1-6 with a 10.80 ERA and four blown saves in 17 outings.
Recalled on May 30 when outfielder Mac Williamson was sent to Sacramento, Calixte batted .160 (4-for-25) in eight games. Calixte started six games in left field and one in right for the Giants, who have used 12 different left fielders this season.
