As far as gear, thermal sports tights and tops, wool or silk ski socks under uniform. Most NE players wear very little beyond their uniforms for games, kind of a macho thing, some (non-pitchers) even sticking with just the uniform, maybe a 3/4 sleeve under. Pitchers are another story and have got to keep warm, especially hands when not on mound, ball is like a cue ball with no feel for off speed pitches, but then again you plug a few hitters in that cold weather and after you can basically serve the ball down the middle and get outs, good rule of thumb is to hit the guy with the most winter clothes on. Most teams travel south first month before conference play anyway. As soon as teams can plow the turf fields in February (most often the football field), it's outside to practice. 33 degrees is a nice day.
