Zack Wheeler has had an unconventional journey since his days as a top prospect in the Minor Leagues. He looked to be a frontline starter for the upstart Mets in 2014 alongside Matt Harvey and Co., but Tommy John Surgery in the spring of 2015 quickly halted those plans. He would return in 2017 with poor results, and he continued to struggle until the midway point of 2018.
Something has changed since then, however, and now he is one of the more intriguing power arms in the game as he nears free agency.
