A close family friend told the Lynchburg News & Advance in Virginia that Bibby, a longtime resident of nearby Madison Heights, Va., died of undisclosed causes at about 9 p.m. ET at Lynchburg General Hospital. He is survived by his wife, Jacqueline, and two daughters, Tamara Bibby and Tanya McClain.
"All of us at the Pittsburgh Pirates are deeply saddened by the passing of Jim Bibby," Pirates president Frank Coonelly said in a team release. "Jim was a well-respected member of the Pirates family, both as a player and a coach.
"Jim won 19 games and finished third in Cy Young award voting for the Pirates in 1980, but will always be remembered in Pittsburgh as a key member of the 1979 World Series championship team. ... Jim started Game 7 of the World Series against the Orioles and put the Pirates in position to take home its fifth World Series Championship.
"Our deepest sympathies, thoughts and prayers go out to his wife, Jacqueline, his two daughters, Tamara and Tanya, his family and friends. He will be missed."
A statement is expected to be released by the family at a later date, according to the News & Advance.
Bibby pitched in the Majors for 12 seasons, from 1972-84, spending five years with the Pirates, four with the Rangers, three with the Indians and two stints with the Cardinals. The right-hander compiled 111 wins with a 3.76 ERA.
Born Oct. 29, 1944, in Franklinton, N.C., Bibby started Game 7 of that Fall Classic against the Orioles and got a no-decision after giving up just one run in four innings in an eventual 4-1 win by his Pirates.
His best season came in 1980, when he went 19-6 with a 3.32 ERA to earn his only All-Star nod. He also threw a no-hitter against the Athletics while with the Rangers in '73.
After retiring, Bibby served as pitching coach with the Lynchburg Mets, Red Sox and Hillcats for 15 years. Then, after a year with the Pirates' Nashville affiliate in 2000, Bibby's contract wasn't renewed, and he retired from coaching.
