On August 10, 1987 — Phillies pitcher Kevin Gross becomes the second pitcher in eight days to be ejected for scuffing the baseball when umpires discover sandpaper in his glove during the 5th inning of a 4 – 2 win over the Cubs. Like Joe Niekro, Gross will be suspended for 10 games, and won’t get his glove returned until August, 1991.
