Baty is with the Mets in Milwaukee as part of their taxi squad, Tim Healey of Newsday reports.
Jesse Winker is dealing with a back issue, which has his status for the National League Wild Card series in question. If Winker is unable to go, it sounds like Baty would be the choice to replace him on the roster. Baty put up a .633 OPS in 50 games during the regular season with the Mets but had a .925 OPS in his final 14 contests at Triple-A Syracuse.
