Jameson Taillon has never lived up to the billing of second overall draft pick - after Bryce Harper and before Manny Machado- but it's really through no fault of his own. Here is what's he has endured - Tommy John surgery in 2014, sports hernia in 2015, testicular cancer in 2017, and after finally having an injury-free 2018 in which he was one of the best in MLB the second half of the season, he suffered a forearm injury in 2019. Further examination showed he needed a second Tommy John, so he won't pitch again until 2021.

But he is already well into rehab, which he has has changed quite a bit since his first TJ rehab 6 years ago. He also gives high marks to pitching coach Oscar Marin and his innovations.
