Notre Dame graduate Jim Hannan's 254 strikeouts (in only 196 innings) in his first pro season led the New York-Penn League in 1961, but he was always plagued by control problems. Taken from the Red Sox organization by the Senators in the second expansion draft, his best year was 1968, when he went 10-6 for the 65-96 Washington team. The lifetime .091 hitter struck out in 13 consecutive at-bats in 1968, an AL record. Hannan was a player representative, and his master's thesis on the Major League pension plan was used by Marvin Miller to acquaint himself with baseball's benefit system.
Fred Valentine was an outfielder in 1959 and 1963-68 primarily with the Senators. He was the Carolina League player of the year hitting .319. In 1966, he had 16 homeruns and led the Senators with 29 doubles and 140 hits. He was also Sports Illustrated's Player of the Week and MVP of the Senators in 1966.
Sandy Alderson is the general manager of the New York Mets and was formerly the CEO of the San Diego Padres and Executive Vice President of Baseball Operations for Major League Baseball. He guided the Oakland Athletics to four division titles, three pennants and the 1989 World Series while he was the team's general manager.
John Doherty was a right-handed pitcher from 1992-1996, primarily with the Detroit Tigers. He led the Tigers in ERA in 1992, when he posted a 7-4 record with 3 saves. In 1993, he led the Tigers in wins with 14.
Denny Doyle was a second baseman from 1970-1977, primarily with the Red Sox and Phillies. A career .250 hitter, he hit .298 for 1975 American League Champion Boston Red Sox.
Brian Fisher was a right-handed pitcher from 1985 to 1992, primarily with the Pirates. His career totals include 640 innings pitched with 370 strikeouts. A relief star for the 1985 Yankees, he led AL rookies with 14 saves while posting a 2.38 ERA. He became a starter in 1987 after 126 straight relief appearances and proceeded to finish among the league leaders in complete games and shutouts.

The colorful "Mudcat" Grant was not only a 14-year Major League pitcher but a broadcaster and entertainer. He spent his first seven-plus seasons with the Indians, compiling a 67-63 record. He then reached his pinnacle with the 1965 pennant-winning Twins, leading the AL in victories and winning percentage (21-7, .750) and in shutouts (six). He defeated the Dodgers in the World Series opener, 8-2, lost Game Four, 7-2, and won Game Six, 5-1, helping himself with a three-run homer. He worked mostly in relief after his trade to the Dodgers in November of 1967 and in 1969 recorded the expansion Expos' first win. With Oakland and Pittsburgh in 1970, he went 8-3 (1.87) with 24 saves. Sporting muttonchop sideburns, he was the lead singer of a group called "Mudcat and the Kittens."
Rich Hand was a Major League righty from 1970-1973, primarily with the Indians and Rangers. He won 10 games for the Rangers in 1972, while carrying a 3.32 ERA. Hend posted 24 wins and three saves before arm troubles cut his career short.

Myers was a member of the 2004 Red Sox World Series championship team and twice led the American League in single-season games pitched. He currently serves as a special assistant with the Major League Baseball Players Association.
Steve Rogers was a right-handed pitcher from 1973 to 1985 with the Montreal Expos. His career totals include 2,839 innings pitched, 158 wins and a 3.17 ERA.
