The Giants activated infielder Marcelo Mayer from the 10-day injured list and selected outfield prospect Bo Davidson to the MLB roster on Monday, per multiple outlets. The moves came before the team's game at Oracle Park.
The promotions were accompanied by roster constraints. Jung Hoo Lee was shut down with a groin contusion, per MLB Trade Rumors. Rookie first baseman Bryce Eldridge was placed on the seven-day concussion list, with the placement retroactive to September 18, meaning he could theoretically return before the season ends, per MLB Trade Rumors.
Davidson made an immediate impression in his debut. Yahoo Sports reported that his "unique blend of power and speed was on display" in Monday night's game. Reddit user JianClaymore noted that Davidson won a nine-pitch at-bat to record his first career hit in his first major-league appearance, though no other outlet provided details on his performance. The Giants have six games remaining in their season.
