This week we saw the arrival–and departure–of reliever Tyson Miller, becoming the first Met since Seth Lugo and the second overall to wear No. 67. We also witnessed the debut appearance of Sam Coonrod wearing No. 45. Coonrod spent the whole year injured.

The real action happened on Twitter where a mystery popped up over the Met pictured below in the No. 55 jersey in a 1984 Old Timers Game. He looks facially like Bill Monbouquette even though Bill wore 54 and wasn’t on the Mets’ staff in 1984.

@Springer66 Do you have any guesses who this number 55 might be? It's from an old timer's game in Denver in July 1984. George H.W. Bush is at left and Tony Oliva is at right. Frank Howard would've been wearing 55 for the Mets at the time but that doesn't look like him. pic.twitter.com/l9eNpLJhBZ
