Late 80's Phillies Jerseys - Zippered/Buttons

I understand that 1986 was the last season the Phillies wore the zippered front. Does anyone know if the team was still using zippered jerseys for spring training through 1988? Reason I ask, I have seen a couple photos post 1986 of players wearing the zippered front. One was the 1988 Donruss card of Pitcher Steve Bedrosian. Granted he was on the team in 1986, but would Donruss be using an 1986 photo for a 1988 card? Another photo I saw was dated 1987 and depicted a player with zippered road jersey. Just curious if anyone has any thoughts on this.

Thanks

The Bedrosian photo was likely from '86. The zippers disappeared in favor of buttons when the Phillies switched to Rawlings per the official MLB uniform deal. The last hurrah for the zipper-front Wilson gamers would have been, at the latest, spring training of 1987.
