Luis Castillo was one of the most accomplished starting pitchers in recent Cincinnati Reds history, but that era came to an end when he was traded to the Seattle Mariners on Friday for four prospects.
Castillo closed his six-year Reds career with a 44-53 record and a 3.62 ERA through 137 starts. He was a two-time All-Star and the Mariners traded for him with the expectation that he’s hitting his prime. Castillo, who won’t reach free agency until after the 2023 season, was statistically the franchise’s best pitcher since Johnny Cueto.
There are only three Reds pitchers who posted an ERA below 3.
