I don't know about juiced bats but the guy from No Limit(Choo Fields) could hit like that since was 16 years old. He can hit 350 plus with any bat. He pulled out an old Easton Redline during league play last week and hit a bomb with that too. Some people can just hit. He is one of them.
I agree with one notion though, there is no way some of these teams in REC are really rec. I saw way too many middle shots this weekend too. I saw way too many HRs for outs. I think they should adopt the deadspot rule for REc like USSSA does in E. Once a guy hits for the last HR, anyone that hits one out after that is out. Anyone that hits in the deadspot is also out. You can play D but cannot bat even if you sub in that spot.
