Mtownfan...My son is approaching 6'0(ha)
, but he got attention when he was 5'9, 5'10 etc. He throws high 80's, but as a So and Jr he was mid 80's. Fotunately, he has a good command of the zone and can throw 3 pitches for srtikes...most of the time.
Don't give up because people talk about height, use it as my son did as a motivator. Throw strikes, get outs and someone will need you. If you a RHP, you should try to be mid 80's in your senior year...that will help.
TR always say's, and I agree, "there is a place for everyone to play if they work hard and put themselves in the right places in front of the right people."
PLay hard and make it happen! Good Luck!
