Reddy Grey got into his only big league game by very lucky timing. The 1903 Pirates were short two position players on a road trip and needed a fill-in for their final game against Boston. Grey was on his way to Worcester that same day to report to his new team. Worcester had the day off, so he filled in for the Pirates, singled, walked and drove in two runs (online stats say one, but numerous sources from the day say two). He left the Pirates after the game and joined his new team.
Grey was a former minor league teammate of Zane Grey, the famous author, who was also his brother.
