Batting Cage/Upper Gym
Go through the swimming pool lobby doors, at the first left after the elevator, go up the stairs to the 2nd floor, make the left, then another right.   At the end of the hall is the entrance to the batting cage/upper gym facilities.

Gym 2 is on the same floor, except that instead of making the left into the batting cage area, go straight through the double doors.   Gym 2 is next to the upper pool entrance on the right side.
