Donald William Aase ( ; born September 8, 1954) is an American former professional baseball pitcher who played in Major League Baseball from 1977 to 1990. During his MLB career, Aase played with the Boston Red Sox (1977), California Angels (1978–84) and Baltimore Orioles (1985–88), of the American League. In the National League, he played for the New York Mets (1989) and Los Angeles Dodgers (1990). Minor leagues Aase was drafted by the Boston Red Sox in the sixth round of the 1972 amateur draft. That summer he struggled with the Williamsport Red Sox, putting up an 0–10 record to go along with a 5.81 ERA. The following season he was with the Winter Haven Red Sox and led the Florida State League with 15 losses. However, he bounced back in 1974 with the Winston-Salem Red Sox, leading the Carolina League in wins, complete games, and shutouts, and was named the circuit's Pitcher of the Year.

In that contest, he replaced Frank Tanana in the sixth inning with a 2–1 lead over the Baltimore Orioles. He gave up runs in the sixth and seventh innings to blow the lead but still earned the victory when the Angels scored two runs in the bottom of the ninth to win the game and stay alive in the series.
