On June 19 , 1972 — Larry Dierker hurls a one-hitter to blank the Mets, 3-0 . Duffy Dyer’s third-inning single is the lone blemish on Dierker’s night. Tommy Helms delivers four hits to lead the Houston offense. The day before, Jerry Reuss had tossed a one-hitter at the Phillies. The back-to-back one-hitters tie a major league mark and establish a club record.
