“Mays always told me how hard it was to get a hit off me and every time I looked up, he was on second base. Yet, even with Mays, I had an idea what to do. When I pitched to Clemente and Aaron, I had no idea. They seemed to hit everything.”
As quoted in "Koufax Still a Champion" by Les Biederman, in The Pittsburgh Press (May 8, 1967)

Context: The 100 grand right fielder revealed that Danny Murtaugh once fined him $650 when he did not run after hitting a ball to the shortstop. He never explained how Murtaugh reached the $650 figure. "I hit the ball and I slip at home plate and they fine me $650. First time up I hit a homer one-handed. I just limped around the bases."
                                    
“I'm ready. They hit me hard. I hit them hard. Doesn't matter who hits. What matters is results.”

Context: The best advice and most help he ever received came from Buster Clarkson, an American player, when he was in Puerto Rico."I played for his team and I was just a kid," Clemente recalled. "He insisted the other players allow me to take batting practice and he helped me. He put a bat behind my foot and made sure I didn't drag my foot. Willie Mays also helped me. He told me not to allow the pitchers to show me up. He suggested I get mean and if the pitchers knocked me down, get up and hit the ball. Show them."
