[3] As a child, he started playing CYO basketball and baseball at Holy Name of Mary parish in Valley Stream, New York, where he made his First Communion and Confirmation.

At Reading, he became a roommate and lifetime friend with Rocky Colavito, a near future Cleveland Indians home run hitter and right fielder from the Bronx, New York.

Score won The Sporting News Minor League Player of the Year Award and began to be referred to as "left-handed Bob Feller".

[5] Score struck out 245 batters in 1955, a major league rookie record that stood until 1984, when it was topped by Dwight Gooden (Score, Gooden, Grover Cleveland Alexander, Don Sutton, Gary Nolan, Kerry Wood, Mark Langston, and Hideo Nomo were the only eight rookie pitchers to top 200 strikeouts in the 20th century).

[7] In 1956, Score improved on his rookie campaign, going 20–9 with a 2.53 earned run average and 263 strikeouts, while reducing the number of walks from 154 to 129, and allowed only 5.85 hits per 9 innings,[6] which remained a franchise record until it was broken by Luis Tiant's 5.30 in 1968.

On May 7, 1957, during the first inning of a night game against the New York Yankees at Municipal Stadium in Cleveland, Score threw a low fastball to Gil McDougald with Jim Hegan catching.

The ball caromed to third baseman Al Smith, who threw McDougald out before he rushed to the pitching mound to aid Score.

"The reason my motion changed", Score told Pluto, "was because I hurt my elbow, and I overcompensated for it and ended up with some bad habits."

He finished with a major league career record of 55–46, a 3.36 earned run average, and 837 strikeouts over eight seasons in 8581⁄3 innings pitched.

[9] On October 8, 1998, while driving to Florida after being inducted into the Broadcasters Hall of Fame[10] the night before, Score was severely injured in a traffic accident.

[11] He pulled into the path of a westbound tractor-trailer truck near New Philadelphia, Ohio, and his car was struck in the passenger side.
