4 come to mind :
Saw Greg Luzinski hit one out of Shea Stadium. Sailed past the Mezzinine and landed behind the visitor BP.
Dave Kingman hit one at Shea to LF/LCF that disappeared and I'm pretty sure went into the parking lot.
Cespedes cranked one at Citi Field near the Acela Club in left that...
Putting my heart aside.
I could see if he went pro that he would be a perfect fit for a team late in 1st round. He's young and talented. A steal in that scenario.
A good team that doesn't need him year 1.
That said I think he gets NBA feedback and comes back.
