Looking at Newsom's career, the first thing that you notice is that he had a losing record of 211-222, and he led his league in losses four times. You also see that he was a vagabond pitcher who played for eight different teams, some of which on multiple occasions. Yet, this is a guy who stuck around a lot and struck out a ton of batters, so the value of Newsom is definitely there.
On three occasions, Newsom was a 20 Game winner, and he was an All-Star in all of those years. Newson won the Strikeout Title in 1942 (113), and in the five seasons leading up to that, he was the runner-up. Newson would end up with a nice number of 2,082 Strikeouts over his career.
While Newson was not known for having a great ERA, he did have four top-ten finishes in that stat, and in regards to overall efficiency, he also had six top-seven ranks in bWAR for Pitchers. Newsom also won a World Series Ring with the New York Yankees in 1947.
