It would seem that Bauer was just having some fun at fans' expense. While Bauer is indeed eligible for free agency this winter, players aren't actually free agents until after the World Series. What's more, they're not allowed to talk to clubs other than their present teams until five days after the Series.
So if Bauer was in Boston, it was not to meet with the Red Sox.
Of course, Bauer's trolling piqued everyone's interest -- achieving exactly what it was designed to achieve.
Make no mistake -- the likely 2020 National League Cy Young Award winner (5-4, 1.73 ERA; 0.79 WHIP; 12.3 K per 9IP) is easily the best available pitcher in a thin free agent market.
And after a disastrous 2020 in which their starters compiled a 5.58 ERA, second-worst in the American League, starting pitching is the Red Sox' most obvious need.
But that ignores two huge factors that all but rule out Bauer as a good fit for the Red Sox.
