Donald John DeMola (born July 5, 1952 in Glen Cove, LI, NY) is former Major League Baseball pitcher. Don played for the Montreal Expos in 1974 and 1975.

Don was drafted out of South Commack high school in 1970 by the Yankees. He won the 1970 Carl Yastrzemski Award, which is awarded annually to the outstanding high school baseball player in Suffolk County, Long Island, NY (Yaz is from Southampton, which is on the south fork of eastern Long Island).

After two minor league seasons, he was released and signed on with the Montreal Expos in January 1973. He made it to the Expo staff the next year, earning his first career win against the San Diego Padres on June 16th, 1974. It was his only decision of the season, as he mostly pitched in middle relief in 25 appearances.

In 1975 Demola earned a victory at Shea Stadium, with his family & hometown friends looking on. He pitched two scoreless innings striking out Rusty Staub, Jerry Grote, Joe Torre & Randy Tate along the way. His battery mate that night was none other than Gary Carter, who was in his first full season. It was a Gary Carter RBI base hit that put Montreal on the board that night, followed (by former & future Met) Mike Jorgensen's three run HR that put the Expos ahead for good. DeMola would make appearances the next two nights as well at Shea, allowing no runs in three innings of work. The Mets won both those games.

Overall on the 1975 season he was 4-7 with a 4.16 ERA making 60 appearances, second on the club (to future Met) Dale Murray. After that, he suffered an injury that required arm surgery, and he appeared in just one game for the Denver Bears of the American Association (AAA) in 1976. He continued to pitch in the Expos minor league system through 1978, but was never able to return to the Major League level. He finished with a 3.77 ERA and a 1.29 WHIP in MLB.
