"You know what's going to happen in the 9th inning, but it takes five hours to get there!"
Yankees legend Ron Guidry clearly dislikes watching the MLB these days ... telling TMZ Sports games just take too damn long to finish!!
We got the ex-pitcher out in NYC when he told us straight-up, "The game has changed, and it's long, and it makes it harder to watch because it's so long."
The MLB has been accused of juicing baseballs this season in order to see more offense ... but all the home runs and scoring has led to much longer days at the park.
Guidry says it's really killing the game ... and he thinks more needs to be done to help speed things up.
His solution to the problem? "Let the pitchers pitch."
Did you expect anything else from a former ace?!?!?!
