4. Brett Anderson
It is kind of amazing Brett Anderson still pitches in Major League Baseball. Since his debut in 2009, the man has played just 3 full seasons, as he consistently misses time due to injury. Whether injuries or just seriously bad outings were the case, his 6 starts with the Cubs in 2017 were something to behold. Anderson managed to collect almost an earned run (20) for all of his 22 innings pitched, notching him an 8.18 ERA. He was transferred to the 60-day Injured Reserve and released by July. Just awful.
