Danny Duffy is pitcher for the Kansas City Royals from 2011 until July 2021. He has been both a reliever and starter for them. As a starter in 2016, he had his best season with a 12-3 record and a 3.51 ERA.
The Kansas City Royals do not have a big payroll and rarely commit large amounts to one player. Therefore when the Royals rewarded Duffy with a 5 year $65 million contract, it was an exception. While Duffy has not been a disaster, his results in those five years resembled a mediocre pitcher rather than a star. He has had 32 wins and 35 losses. While he has been pitching for a poor team, his ERA was consistently over 4.00. The point is that he never returned to the starter of 2016. After 12 wins in 2016, he never won 10 games during his contract. With just two months left in the contract, he was traded to the Dodgers in July 2021 to help their bullpen.
