Moose passed in 1976 at the age of 29 and is one of the most elusive signatures for anyone trying to complete signed sets from the 1970s, but played in the big leagues 1967 to 1976. Moose spent his entire career with the Pittsburgh Pirates (including the World Championship season of 1971). His best season came in 1969 when he posted a 14–3 won-loss record and a 2.91 Earned Run Average working equally as a starter and reliever. On September 20 of that year, he no-hit the eventual World Series champion New York Mets. He is also known for his wild pitch in the bottom half of the ninth inning which allowed George Foster to score the winning run in the fifth and deciding game of the 1972 NLCS, sending the Cincinnati Reds to the World Series after Pittsburgh had a one-run lead entering the bottom of the ninth, in the final game of Roberto Clemente's career. During the 1974 season, Moose suffered a blood clot under the shoulder of his pitching arm. Surgery was required to remove the clot plus one of Moose's ribs. Moose was killed in an auto accident heading to Bill Mazeroski's golf course near Martins Ferry, Ohio, on his 29th birthday. We offer a signed handwritten letter with a signed original mailing envelope to his future wife. Touching letter.
