View Draft Report
Bartnicki has an interesting background as an athlete who developed a reputation as an impressive swimmer before he began to progress on the baseball field. A 6-foot-3, 210-pound lefthander, Bartnicki brings physicality to the mound and a broad frame unusual for a swimmer of his caliber, but one that is perfect for a durable arm on the mound. The Georgia Tech commit has reached the mid-90s in shorter stints, but mostly sits in the 89-92 mph range, with natural arm-side run and sink on his fastball from a lower three-quarter arm slot. He has a slider that's been inconsistent this spring, looking like an above-average pitch with late-breaking action at times but also backing up and showing well below-average with poor spin and bite. He's shown solid feel for a low- to mid-80s changeup as well that should become an average offering. Bartnicki has a slightly unorthodox delivery that can get out of sync at times but also leads to above-average deception and helps his fastball play up. The southpaw has a lot of exciting ingredients, such as his size, strength and athleticism. He could take huge steps forward as he gains consistency with his secondaries and refines his delivery.

Draft Prospects
Bartnicki was part of a loaded 2018 Georgia high school pitching class that also included righthanders Kumar Rocker, Ethan Hankins and Cole Wilcox. While Bartnicki wasn’t quite at their caliber at the time, ranking as the No. 112 player in the class, he showed exciting ingredients between his size, strength, athleticism (he was a standout swimmer) and funky delivery. Bartnicki has bounced between relieving and starting while at Georgia Tech, but in both of his two full seasons he’s worked primarily out of the pen. This spring he posted a 6.00 ERA over 42 innings while striking out 41 batters (8.8 K/9) and walking 22 (4.7 BB/9). Scouts like his deception on the mound and the Trackman attributes of his pitch mix, but note that his control has been inconsistent and held him back. He works with a three-pitch mix that includes a low-90s fastball with heavy running action, a sweeping, upper-70s slider and a low-80s changeup that remains a work in progress. Bartnicki has an extended and inverted arm action in the back of his arm stroke and throws from an arm slot that is close to fully sidearm. He currently profiles as a bullpen piece who could give hitters a unique look, but might get a chance to start for a team that thinks he can improve his control and changeup.
