...and this dude is BIG!!

We caught up with Jon and his cute little brood at a baseball game in Reading, PA, yesterday.

Everyone knows his soon-to-be ex-wife Kate has her own personal minder to keep her safe

But, in case of any trouble(LoL), looks like Jon took along some of his own hired muscle to keep the over-excited fans in check.

Police say there were no crowd problems, so maybe Jon will take his new charge to the West Coast when he hits up Vegas this weekend. That's if he/it will fit on the plane...

Check out Jon, the kids and the Giant in the gallery below...
