Ryne Sandberg of the Chicago Cubs turns a double play as outfielder Kevin Mitchell of the San Francisco Giants slides into second during a 1990 season game at Candlestick Park in San Francisco, California.
Yes, that’s definitely Ryno. And it’s also Kevin Mitchell, and the game is obviously a Cubs road game, so it has to be at Candlestick Park.
Further, this photo was definitely taken in 1990, because the Cubs had ditched the blue pullover/white pants road look they’d worn since 1982 that year, and switched back to a traditional road gray button-front shirt.
