Chipper Jones says his knees took so much punishment during his Hall of Fame baseball career, he can't even play in an adult softball league these days.
The 44-year-old spent 19 years in the Bigs -- and tells TMZ Sports he underwent SEVEN knee surgeries.
"My knees are shot man," Jones says ... while explaining why he won't join a rec team.
We already knew about 3 operations on a torn ACL in left knee (2010), torn meniscus in right knee (2011) torn meniscus in left knee (2012) ... but no word on the other 4 procedures.
Still, Jones was in a good mood when we got him and even told us if he thinks Barry Bonds will make Cooperstown one day.
