Baseball’s unwritten rules have left Pete Rose a little flushed.

The maligned infielder, now in his own reality television series, called acts of common courtesy in the sport “stupid”.

In an interview with Grantland, ESPN’s sports and pop culture website, Charlie Hustle said he doesn’t acknowledge the don’t bunt against a pitcher with a no-hitter rule or taking an extra base with a big lead.

“I used to get screwed when we had a seven- or eight-run lead, because I couldn’t bunt for a single or I’m ‘showing up the opposition,’ ” Rose told Grantland. “Guys that are home-run hitters can continuously just swing from their ass and trot around the bases.”

Rose recalled his encounter with Houston Astros pitcher J.R. Richard. The Reds were up 7-1 in the sixth inning and Rose smacked a single to right-centre and he ran for second.

Richard would throw at the next two hitters because Rose was “showing the team up”.

“What am I supposed to do when I got a 10-run lead, just go up there and strike out?” he asked.
