Jonathan Loáisiga always had the arm. Even when he was pitching ineffectively to start his career, you could see why the organization was so bullish on his development. The only issue was that he simply could not stay on the field. The San Francisco Giants released him after missing 2014 and 2015 to injuries, and he pitched in just one game before having Tommy John surgery in 2016. In 2019, a shoulder injury in May limited him to just 31.2 total innings. In the shortened 2020 season, Loáisiga was able to manage just 23 innings as a bullpen arm and spot starter.
