Draft Prospects
Drafted in the 28th round by the Phillies out of high school, Sullivan is considered a top-three college pitcher in the Northeast area based on pure talent, however concerns over his Tommy John surgery prevent him from being higher on this list. As a freshman, Sullivan was voted the Colonial Athletic Association’s rookie of the year in 2018 after leading Delaware in strikeouts (95) and opponent batting average (.199) to go along with a 7-3, 2.97 mark in 72.2 innings. He made just two starts as a sophomore before undergoing Tommy John surgery and has not pitched in a live game since. He was scheduled to return by the start of April before the coronavirus pandemic shut down the season. Sullivan is regarded as an exceptional athlete with good makeup, and impressed evaluators by the work he put in during his rehab process. He pitched well in rehab settings over the winter, but there isn’t enough of a sample size for a team to risk taking him in a five-round draft. At 6-foot-2, 195 pounds, Sullivan relies on his excellent fastball that snaps out of his hand around 98-99 mph from the right side. Sullivan will likely end up as a reliever, where his fastball will play up in shorter stints. He should be one of the top seniors in the 2021 class if he is able to get back to his previous form.
