Matt Garza had been a successful pitcher for several teams, having his best seasons with the Tampa Bay Rays from 2007 through 2010. As a free agent in 2014, The Brewers signed the 31 year old starter to a 4 year $50 million contract. In 2014 he pitched 163 innings, had a 3.64 ERA and finished 8-8.
The wheels came off in the second season. Towards the end of the year he was removed from the starting rotation due to poor performance. He ended up 6-14 with an ERA of 5.63. The next year was hardly impressive going 6-8 with a 4.51 ERA. He had an injury in the fourth season and finished 6-9 with a 4.94 ERA. In total the 4 years produced a record of 26 wins and 39 losses.
No team picked him up and he never pitched again using the $50 million for a comfortable retirement.
