McCray went 0-for-4 with a strikeout in Wednesday's 13-2 loss to Atlanta.
McCray's major-league debut was a forgettable one for both him and his team. The outfielder slashed .272/.347/.471 over 47 games with Triple-A Sacramento this year after earning a midseason promotion from Double-A Richmond. McCray's strong defense makes him a candidate to play regularly in center field. The Giants moved Heliot Ramos to left field and Michael Conforto to designated hitter Wednesday, which could be the usual alignment versus right-handers moving forward, as long as McCray plays well enough to keep his spot in the lineup.
