Pitchers, Game Temperature and Throwing Strikes

I have always figured pitchers have an early advantage in the season because balls hit in cold weather don’t travel as far. After watching teams try to pitch in the miserable weather of the last few days, I was wandering if there was a point where the cold weather affects the pitchers also. The main item I noticed was the pitcher’s in ability to consistently throw strikes. I decided to look at the Zone% for all pitches depending on the temperature. Here are the results:

Temp Zone% % of Total Pitches
<40 29.8% 0.3%
40 to 49 40.2% 2.3%
50 to 59 43.2% 8.5%
60 to 69 44.2% 23.6%
70 to 79 42.8% 37.2%
80 to 89 41.7% 21.5%
90 to 99 43.7% 5.9%
>=100 44.0% 0.7%

TempVsZone

Hitters don’t hit the ball as far in colder temperatures, but when the temperature is under 50 degrees, pitchers have issues throwing strikes.
