Chipper Jones’ baseball skills have apparently deteriorated over the years … ’cause the MLB legend just embarrassingly fumbled an attempt at catching a foul ball Monday.

The former Braves star’s gaffe just went down in the second inning of Atlanta’s playoff tilt with the Brewers … when Milwaukee 2nd baseman Luis Urias hit a pop fly toward the ex-3rd baseman, who was sitting just a few rows behind home plate.

The ball was hit sky-high … and despite camping underneath it and having a Hall of Fame baseball resume — Chipper muffed the grab!!

The ball clanked off the 49-year-old’s mitt … and it ain’t hard to see in the broadcast footage that he was pretty embarrassed.

The game’s announcers had fun with the moment, with one ruling it an error — and the other adding, “Poor Larry. That’s going to be all over the place today.”

In Chipper’s defense, he hasn’t played in a Big League game in 9 years … so the debacle is at least kind of forgivable.

Then again, dude is an 8-time All-Star … so, yeah. Make the grab, Chipper!
