View Draft Report

Sullivan teamed with Grant Holman to give Cal one of the most touted starting pitching duos on the West Coast this spring. After impressing in the Cape Cod League in 2019, he took over as the Golden Bears’ Friday night starter this season and went 4-5, 3.68 with 75 strikeouts and 22 walks in 78.1 innings. Sullivan is an athletic righthander with four pitches, an advanced feel for pitching and a competitive streak on the mound. His fastball averages 90-91 mph and touches 94, and he effectively mixes in his above-average slider, average curveball and average changeup to keep hitters guessing. Though none of Sullivan’s offerings is plus, everything plays up with his command and feel for sequencing. He has excellent fastball command and can throw any of his secondary pitches for a strike at any time. Sullivan is young for the class and still has room to add weight and strength to his frame. He has a clean delivery and arm action and is an excellent athlete who gets off the mound and fields his position well. Sullivan projects as a safe back-end starter for most evaluators. If he adds strength and starts throwing harder, he has a chance to be more.
