The Indians made a poor trade to the Boston Red Sox in 1934 that ended up being a steal for the Red Sox. Even better, Wes's brother, Rick, was the catcher for the Red Sox. Rick, of course, is in the Hall of Fame. It was pretty cool for Wes to be able to pitch to his brother, and he enjoyed three of his best career years in Boston. The wheels fell off for him in 1937, though, and he and his brother were both traded to the Washington Senators. Wes actually pitched much better for the Senators for the rest of that season, but fell apart after that, and was miserable for the rest of his career. Rick didn't do so well in 1937, but he played until 1945 culminating in what became a Hall of Fame career. In return, though, the Red Sox acquired Bobo Newsom and Ben Chapman. Chapman was decent for Boston, putting up an .885 OPS, though Newsom was only okay and gone after the season. The Red Sox would end up missing Rick Ferrell, but not Wes.
Farrell never had a full season ERA below 3.31, but he had an ERA+ of 116 for his career, meaning he was about 16 percent better than league average. Also, his walk to strikeout ratios were pretty bad (3.6 BB/9 vs 3.4 K/9). His value mostly came from pitching tons of innings. He also had some good offenses backing him during those years. Plus, Wes himself is perhaps the greatest hitting pitcher of all-time, hitting 38 home runs in his career, an MLB record. He also had a MLB record 9 home runs for a pitcher in 1931 for Cleveland. He was certainly an above-average pitcher who added a ton of value with the bat, but not a Hall-of-Famer like his brother. Wes Farrell passed away at the age of 67 in 1976. You will be missed, Wes.
