On the title screen, hold down the B button and press Start to enter the hidden Ball Speed Mode menu with four options allowing you to: 1) adjust ball throwing distance, 2) pitch the ball, 3) catch the ball and 4) reset to try again. You can try and beat your max ball speed!
There is no option to exit this menu unfortunately, so you need to turn off or reset the console if you want to return to the title screen.
