Funny, we were talking just last night about a line one of my dd's coaches used on us. My dd was 5'5" and 105 lbs when she was 14. He says "did you give her a key to the refrigerator yet"
for pitchers are struggling with their control, I may remind her that her partner is "a catcher, not a fetcher"
"you are, what your record says you are"
when the ump's strike zone is larger than I prefer, it is a "Sunday School Strike Zone: Deep and Wide"
