1. Playoff rosters can be tweaked round-by-round. Leaving Taijuan Walker off against the Padres is a practical choice, not a judgment on whether he pitches against the Dodgers. 2. Joely Rodriguez: In 4 appearances this year against SD, he has a 37.60 ERA. 9 runs, 7 earned. Retired only 5 of 17 batters he faced. 1 K, 5 walks, 7 hits (one was a homer). I'm not so sure he's on the roster this first round. 3. Tomas Nido is going to start at catcher. This appears to have been conceded when Nido actually hit for McCann on Sunday in Atlanta. But with Alvarez around, would McCann just be left off completely? 4. In a short series, offensive flexibility will be more important than the bullpen. Of course the Mets will take Diaz, Ottavino, Lugo, Smith, May, Peterson, and a “long reliever” (Williams or Carrasco). But Megill or Givens or anyone else is likely to be superfluous here, and allow some extra bench flexibility.
