“It was here that Mays amazed again. He scooped the ball up at the base of the 406-foot sign, whirled and fired. It came in on one bounce, directly in front of the plate, and into the glove of catcher Tom Haller, who put it on the astonished Willie Stargell. It was described by old-timers as the greatest throw ever made in ancient Forbes Field, but it was a costly one. Mays hurt himself on the heroic effort.”

Context: “I do not read too much these days about Jerry May, but he is worthy of a story. He is the best defensive catcher I have seen in my 13 years with the Pirates. In fact, I have not seen many better defensive catchers anywhere in my time in baseball. A story now would do him good, make him feel appreciated. How you say, the time is appropriate?" Clemente always knew May could catch but May has opened his eyes in the formidable way he blocks the plate with a runner and the ball both bearing down on him. "He’s a take-charge catcher. He bosses the player throwing the ball – I tell you, that kid amazes me."

Context: [Clemente] goes back to the ball he hit in Wrigley Field, Chicago. He rates this one No. 1 for distance, perhaps 600 feet. Clemente, himself, paced off the distance from the centerfield wall to the scoreboard right above and when he was shown the spot where the ball landed, he knew this was No. 1. "I hit one off Sam Jones one night over the left-center fence at Candlestick Park and that was a good one," he said. "And two I remember off Sandy Koufax. One over the right field fence at the Coliseum, the other here at Forbes Field. This one hit a transformer on the left-field light tower on the way up and it stopped. No telling how far it might have gone. And you remember I came within a few inches of putting one on the right field roof here.".

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."
