Martin was omitted from Atlanta's NLDS roster against the Brewers, David O'Brien of The Athletic reports.
The righty's 5.40 ERA and .896 OPS allowed in his last 10 appearances was enough to merit exclusion from the initial postseason roster. If Atlanta advances to the NLCS, either Martin or fellow reliever Richard Rodriguez have a chance of rejoining the roster, but their uninspiring performances of late suggest that's unlikely.
