It is on the same field that former A wide receiver Bruce Maxwell in 2017 became the first big leaguer to kneel for the anthem.
Kapler, who started his first season managing the Giants after two disappointing years guiding the Phillies, has not discussed his intention to kneel in a pre-game session with members of the media.
Kapler has been outspoken about social injustice and racial issues and the role of athletes in spurring positive change.
“They felt convinced about the problem so they knelt down,” A pitcher Mike Fiers said.
Former San Francisco 49ers quarterback Colin Kaepernick began to hit a knee during the national anthem in 2016 to protest racial inequality and police mistreatment of minorities. He has been heavily criticized for years, but public sentiment has changed since George Floyd died in May.
Floyd, a black man, died after a white Minneapolis policeman pressed his knee into Floyd’s neck as Floyd was handcuffed and said he couldn’t breathe.
