Doubleheader, double debut

Benjamin Grimm Apr 24 2012 07:16 AM

Yesterday we saw something rare in Mets history: two players making their Mets debuts on the same day, but in different games. This was only the seventh time that such a thing has happened, and only the second time that it wasn't during the expanded roster days of September. August 6, 1967 Game 1: Cal Koonce Game 2: Billy Wynne September 19, 1969 Game 1: Bob Johnson Game 2: Jessie Hudson September 15, 1971 Game 1: John Milner and Buzz Capra Game 2: Don Rose September 1, 1984 Game 1: Herm Winningham Game 2: Calvin Schiraldi September 7, 1986 Game 1: Stan Jefferson Game 2: Dave Magadan September 8, 2011 Game 1: Chris Schwinden Game 2: Val Pascucci April 23, 2012 Game 1: Jeremy Hefner Game 2: Jordany Valdespin

Can your magic spreadsheet conjure whether five or more players making their ML debut in April with the caveat being that none of them were on the roster for opening day is a first in NYM history or is it something more akin to the norm? (NOOOOORM!) This year has so far featured debutants Nieuwenhuis, Valdespin, Lutz, Hefner, and, presumably before the week is out if not today, Carson. Seems to me that the situation featuring this many guys showing up in April but not from day 1 would be unusually high, but maybe not.

Hefner isn't an MLB debut, but we've gotten three in three games, two days, and may add another tonight.

Ceetar wrote: Hefner isn't an MLB debut Yeah it is. He came up through the Padres system but never played for their big league club. This question doesn't limit itself to only those who have been NYM property all along, just for those breaking in for the first time during April but weren't there from the very beginning of the year.

No, I don't think I can do that. I don't have data about who was on the roster when, just when they played. This April certainly does seem more volatile than most though.

So we'd have to start with what you could do which is to generate a list of those who made NYM April debuts (rather lengthy I'm sure) and then cull it manually from there by checking on call-up dates and previous ML experience. Hmmmm, a bit more work than I was bargaining for.

This data has to be available via b-r and retrosheet right? wish I'd set up that database.
