Ooh, neat. Clicking through this list, and I thought there was no way Doug Simons had that many AB: https://www.tcdb.com/ViewCard.cfm/sid/172/cid/78338/1991-Upper-Deck-Final-Edition-63F-Doug-Simons
Sure enough, he only had four as a Met, so I decided to do a little detective work. Three of his four PAs were at home, so that narrows it down a bit. All three were day games, so that doesn't help, but the on-deck batter might.
The on-deck batter for his three AB would have been Vince Coleman (vs LHP John Smiley), Garry Templeton (vs RHP Roger McDowell), and Keith Miller (vs LHP Tom Glavine). It's not the Templeton game, because Templeton would have been warming up batting lefty.
So that leaves Coleman and Miller as the two options for the on-deck batter:
Coleman game, April vs Pittsburgh: https://www.baseball-reference.com/boxes/NYN/NYN199104280.shtml
Miller game, September vs Atlanta: https://www.baseball-reference.com/boxes/NYN/NYN199109080.shtml
They were roughly the same size (5'11"ish, 170ish), so the differentiating factor would be race, but you can't quite see any skin on the batter, so it's hard to tell. In either case, Simons would have been up there swinging, not bunting, because there was nobody on base.
So close!
