They’ll be one more player in the skies over Major League Baseball post season games Tuesday night.

Shortly before midnight, the constellation Orion – the hunter – has dropped his club and instead has the waning gibbous moon in his pitching hand. His shield, of course, forms his glove.

Orion looks as if he’s about to deliver a knuckleball. I’m reminded of knuckleballers of the past, especially R.A. Dickey who played with a number of teams including the Rangers, Blue Jays and Greg Fishel’s Mets.

The moon passes through this part of the sky each month, but it is less visible this time of year as it doesn’t rise until later, closer to midnight.
