�The biggest thing for me was just adjusting to the velocity, of seeing 90 to 92 [MPH] every day,� said Doyle. �You see that speed in college, but just not as much, and here you see it every day.� I'm sure he means when batting but I wonder if catching pitchers that throw that hard everyday takes an adjustment as well. In college players use metal bats, so Doyle is also getting used to using wooden bats in professional baseball. �It was a little bit of an adjustment,� he said. �But I had used them in summer ball.� Why? Are the wooden bats lighter? Heavier?
