Jake McGee is a relief pitcher with the San Francisco Giants. He has pitched in the majors for 12 seasons. This Swing Badder contract occurred in 2017. The Colorado Rockies signed him to a three year $27 million contract. In 2016 with the Rockies he had 15 saves and an ERA of 4.73. The next year he dropped his ERA to 3.61 saving only 3 games.
The Rockies were so encouraged by the ERA, they offered a generous $27 million contract. The results were instantly horrible. That year he had 1 save and an ERA of 6.49. In 2019, he spent time on the disabled list and pitched in 45 games with a 4.35 ERA. Without pitching in 2020, the Rockies gave up and released him in July.
To add insult to injury, McGee signed with the Dodgers and had an ERA of 2.66 in 2020. The next season, he saved 31 games for the Giants with an ERA of 2.72.
For the Rockies, it was two seasons of production for three seasons of compensation. He had 1 save and ERA of 6.49 and 4.35. That was $27 million for horrible production from a pitcher who stayed in the division and pitched two good seasons against the Rockies. That is a Swing Badder contract with sting at the end.
