A 21-year-old Clemens earned his first career win vs. the Twins on May 20, 1984.

Roger Clemens had one of the dominant pitching careers in MLB history.

Drafted by the Red Sox in 1983, Clemens quickly rose through the minors and made his debut with the club on May 15, 1984. The 21-year-old gave up four earned runs on 11 hits in 5.2 innings pitched. Boston lost 7–5 to the Indians.

Five days later, Clemens returned to the mound to face the Twins at the Hubert H. Humphrey Metrodome. He bounced back from his first outing with seven strong innings, in which he surrendered four runs and seven hits. Clemens also recorded seven strikeouts and only one walk in the Red Sox’ 5–4 win, the first of his career. 

Clemens finished his rookie season with a 4.32 ERA, a 9–4 record and 126 strikeouts. His early games were a sign of things to come.
