can anyone shed some light on this Hall of Fame patch? (why it was worn, by whom, etc)

i can't figure it out. i thought it might've been for the annual Hall of Fame Game but in 1989, the Pirates didn't play in the HOF Game. according to the HOF itself:

"Plane Malfunction Creates Split-Squad Game, July 24, 1989
The game scheduled between the Boston Red Sox and Cincinnati Reds was cancelled. The Reds, who had just been swept in a four-game series in Montreal, encountered problems with the airplane's hydraulic system before getting off the ground in Montreal. Instead, the Red Sox played a split-squad game: Boston versus the "Yastrzemskis," in honor of Carl Yastrzemski, who had been inducted a day earlier. The two teams played even ball, tying at 4-4 in a seven inning game. Wade Boggs, Jim Rice, Nick Esasky and current Indians manager (then Red Sox catcher) Eric Wedge all hit home runs. Wedge joined the team after winning the NCAA Baseball tournament as a member of the Wichita State team, the previous month. Al Bumbry, a Red Sox coach at the time and four years retired, was 2-for-3 with a stolen base."

i've never seen that patch on any other 1989 jerseys.
