On May 29, he pinch-hit in the sixth inning, drew a walk, scored the tying run, then had a two-RBI single against Ted Abernathy in the next inning to help the Senators beat the Cleveland Indians 8–4. August 4, he hit a bases-loaded two-RBI single against Sonny Siebert, putting the Senators ahead to stay in a 4–2 victory over Cleveland. He played 143 games (506 at bats) for the Senators, batting .267 with 56 runs scored, 135 hits, 17 doubles, one home run, and 34 RBI. On April 14, 1965, Blasingame had a two-RBI triple against Dick Radatz that put the Senators ahead to stay in a 6–4 victory over the Boston Red Sox. Three days later, he had three hits and drove in the Senators' only run in a 2–1 loss to the Chicago White Sox. His two-run single against Pete Mikkelsen on July 18 helped the Senators win a 3–0 victory over the Yankees.
