Anthony Andro of the S-T was kind enough to email me to clarify a mistake I made in one of the comments regarding awards balloting.
Per Anthony, here's the rule:
All awards ballots are due after the games of Sunday, Oct. 4, unless there are playoff games to decide division winners and/or wild cards. Such games are considered part of the regular season.
So if Porcello pitches a no-hitter tomorrow, anyone who hasn't sent in their ballot already (and I'm sure there probably are a couple of folks who have already sent them out) and has a ROY vote can certainly take that into account in their voting.
