When you start your career the way Domingo Santana did, you don't always get a second chance.
In a brief taste of the big leagues with Houston in 2014, Santana struck out 14 times in 18 plate appearances, a shocking 77.8 percent strikeout rate. He continued his whiff-happy ways with the Astros in limited playing time in 2015, striking out 17 more times in 39 plate appearances. When Santana was eventually sent to Milwaukee in the deal that sent Carlos Gomez and Mike Fiers south, his Houston career was over with a 52 percent strikeout rate.
