7. Pete Alexander, 373 wins, 2.55 ERA, 5,190 innings, 2,198 strikeouts, 120.2 bWAR
Grover Cleveland Alexander made a big splash into baseball, winning 28 games to lead the majors, leading the majors with 7 shutouts, and leading the National League with 367 innings pitched for Philadelphia as a 24 year-old in 1911.
Unlike many of the “dead ball” era pitchers, Alexander was not a guy who pitched purely to contact and “slung” the ball toward the plate. Many attribute the modern windup and delivery pitchers use to Alexander’s delivery, which allowed him to still toss 243 2/3 innings at 41 years old with excellent movement on his stuff within the zone, even though he’d lost his best velocity.
Alexander led the league in wins for four straight seasons from 1914-1917, posting six straight seasons of sub-2 ERA. Incredibly, he won three pitching triple crowns (leading league in wins, ERA, and strikeouts) – tied for the most of any pitcher in MLB history, and though he only finished inside of the top 10 in MVP voting once, Alexander led his league in bWAR six seasons.
Overall, Alexander led his league in wins six times, in ERA four times, in innings seven times, in strikeouts six times, in complete games six times, and in shutouts seven times.
He was elected to the Hall of Fame in 1938 with 80.9% of the vote.
