One of the best 2022 Draft prospects among NCAA Division I transfers, Mazur spent his first two college seasons as the No. 1 starter at South Dakota State. After posting a 5.50 ERA in 16 starts over two years with the Jackrabbits, he opened eyes by earning all-star honors in the Cape Cod League last summer with a 1.55 ERA and 34 strikeouts in 29 innings. The 2022 Big Ten Conference pitcher of the year, he should become the University of Iowa's first top-three-rounds choice since the Royals selected Wes Obermueller in 1999's second round.
Mazur throws two different fastballs, a four-seamer that sits at 93-95 mph and tops out at 99 and a two-seamer at 90-94 mph with good sink. His best offering is an 82-86 mph slider that reaches 89, features two-plane break and grades as plus when it's on. His changeup is a bit firm in the mid-80s but dodges bats with some late tumble, and he also can mix in an upper-70s curveball to give hitters a different look.
Mazur has a quick arm and plenty of room to add weight to his lean 6-foot-2 frame, so he could continue to get better. After averaging 4.4 walks per nine innings at South Dakota State, he cut that rate to 1.9 on the Cape and 2.9 at Iowa. He ranked seventh in NCAA Division I in opponent average (.178) this spring and has the makings of a legitimate three-pitch starter.
Mazur went from a decent starter at South Dakota State to the 2022 Big Ten Pitcher of the Year for Iowa, and that momentum carried into that year’s Draft, where he went to the Padres in the second round and signed for slightly below slot at $1.25 million. He reached Double-A by the end of his first full pro season and San Diego two months into his second. After he scuffled in three short stints with the Padres, they sent him to the Marlins in the Tanner Scott/Bryan Hoeing deal in July.
Standing at a wiry 6-foot-2, Mazur sits at 94-96 mph and touches 98 with his fastball. His control of the pitch was stellar in the Minors out of a fairly high slot, and because he could get ahead of so many batters, he could work in his solid secondaries. A mid-80s slider remains the star with tight, late break, allowing for a healthy amount of chase. His upper-80s changeup has stepped forward, giving him an armside option with fade and sink when it's on, while his 78-81 mph curveball splits the plate with decent vertical break.
Mazur’s athletic delivery helps him repeatedly pump strikes into the zone, though he didn't pitch with the same confidence in San Diego. He didn't challenge big league hitters, fell behind in the count and got hit hard. A lack of more than two above-average pitches dilutes his ceiling some, but so long as he can get through a lineup twice, he should still fit the modern mold of a starting pitcher.
Mazur had one of the most interesting collegiate paths in the 2022 Draft, having gone from an OK starter at South Dakota State to a Cape Cod League breakout All-Star to a spot in the Iowa starting rotation. During his one year with the Hawkeyes, he was named 2022 Big Ten Conference Pitcher of the Year after posting a 3.07 ERA and 0.96 WHIP with 98 K’s in 93 2/3 innings. That helped vault him into a spot in the second round and to the Padres at No. 53 overall, where he was Iowa’s highest pick since 1990.
The 6-foot-2 right-hander stands out as a starter for his deep five-pitch arsenal, headlined by an 82-86 mph slider that comes in with tough two-plane break. He sports two different types of heaters between his 93-95 mph four-seamer and 90-94 mph sinking two-seamer, and he can touch as high as 99 when he needs it. His mid-80s changeup and upper-70s curveball grade out much more average, but both give a diversity of looks that can keep hitters off-balance.
Mazur’s control improved over his three years in the NCAA, and he sported just a 5.4 percent walk rate during his time on the Cape. He has a wiry frame now, giving some scouts hope that more strength and velocity could still be coming. If it does, Mazur’s status as a potential mid-rotation Major League starter would be all the more secure.

How this works: Every pitch is affected by the forces of gravity,
which means that every pitch drops on its way from the mound to the plate.
These numbers are reported with gravity, which makes them larger and
different than other pitch movement numbers you may have seen. Since gravity
requires time, and slower pitches aren’t ‘better’ just because they have
more time to move, the movement of a pitch is compared to ‘average’ movement
by comparing it to other MLB pitch types within +/- 2 MPH and from within
+/- 0.5 feet of extension and release.
