"Walter Johnson, the Idaho phenom, who made his debut in fast company yesterday, showed conclusively that he is perhaps the most promising young pitcher who has broken into a major league in recent years."The Washington Post - Washington, DC - Aug, 3, 1907 - Page 8
A newspaper account of Walter Johnson's debut on August 2, 1907. He apparently had quite the reputation already and his debut did not disappoint. He would continue his entire career with the Senator's becoming one of the most celebrated and dominating players in baseball history. Johnson established several pitching records, some of which still remain unbroken. He remains by far the all-time career leader in shutouts with 110, second in wins with 417, and fourth in complete games with 531. He was the only player in the 3,000 strikeout club for over 50 years until Bob Gibson recorded his 3,000th strikeout in 1974.
Ty Cobb was quite impressed with the youngster. Cobb recalls:
"On August 2, 1907, I encountered the most threatening sight I ever saw in the ball field. He was a rookie, and we licked our lips as we warmed up for the first game of a doubleheader in Washington. Evidently, manager Pongo Joe Cantillon of the Nats had picked a rube out of the cornfields of the deepest bushes to pitch against us. ... He was a tall, shambling galoot of about twenty, with arms so long they hung far out of his sleeves, and with a sidearm delivery that looked unimpressive at first glance. ... One of the Tigers imitated a cow mooing, and we hollered at Cantillon: 'Get the pitchfork ready, Joe—your hayseed's on his way back to the barn.' ... The first time I faced him, I watched him take that easy windup. And then something went past me that made me flinch. The thing just hissed with danger. We couldn't touch him. ... every one of us knew we'd met the most powerful arm ever turned loose in a ball park."
