Parker was never overly popular with the Pirates fans. I clearly remember fans throwing things at him including nuts & bolts and ever batteries.
He was also part of the infamous drug ring in the Pirates Club House. Which reminds me of a great prank done by someone. A local Drugstore Chain ran billboards listing them as “Pittsburghs #1 drugstore” or something similar. So someone vandalized a sign by spray painting “The Pirates Clubhouse” over the name, truly classic. I need to search for any pics online.
Also note the mascot “Pirate Parrot” was involved in dealing the coke to players.
