Programming note: Giants-Royals coverage starts today at 4:30 p.m. with Giants Pregame Live on Comcast SportsNet Bay Area.
The Giants placed first baseman Brandon Belt back on the 7-day disabled list for players with concussion symptoms after he felt sick and wasn’t able to start Thursday at Milwaukee.
Rookie second baseman Matt Duffy, who had just been optioned back to Double-A Richmond on Thursday to clear roster space for Angel Pagan, never left the team and was recalled. Duffy is starting at second base against Royals left-hander Jason Vargas as the Giants begin a three-game series at Kauffman Stadium Friday night.
Belt sustained a concussion July 19 when Marco Scutaro inadvertently hit him in the face with a thrown ball during batting practice at Miami. Belt started that game and scored a run before he felt ill and was removed in the third inning.
His symptoms subsided and he was activated Saturday against the Mets at Citi Field; he had two hits that day, then hit a home run the following day. But Belt struck out four times Wednesday at Milwaukee and told trainers he did not feel well. At first Giants manager Bruce Bochy told reporters that the illness was not related to the concussion. But Belt was to be examined again after the team arrived in Kansas City.
Belt won’t be eligible to return until Aug. 15, when the Giants begin a three-game home series with the Philadelphia Phillies.
Michael Morse is in Friday’s lineup at first base for the Giants.
