 Sisler was solid for much of the first half of the season, not allowing an earned run until May 19, and by June 5 he had an ERA of 0.74, a 1–0 record with seven saves.It was at the point that his effectiveness declined rapidly, allowing runs to score in four of his next five appearances.In a game against the Red Sox on June 18, he relieved starter Carl Mathias, and immediately gave up bases on balls to the first two batters he faced, which forced in two runs, then gave up a grand slam to Jim Pagliaroni.
