Marco Estrada was renowned for being the master of the changeup during his tenure with the Blue Jays. The soft tosser perfected the art of changing speeds and made many a batter look silly at the dish during his days in Toronto. Unfortunately for Estrada, he also became well known for a wonky back that was the cause of his eventual demise and inflated earned run average.
The 36-year old signed a $4 million dollar pact with the Oakland Athletics for the 2019 campaign, however, he only managed five starts before once again succumbing to the nagging back ailment.
