Adam Mazur

Organization Prospect Rankings

• 
  Ranked San Diego Padres #10 prospect in 2024
  BA Grade: 50/High
  
  Track Record: Mazur began moving up draft boards with an impressive stay as an all-star in the Cape Cod League, where he posted a 1.55 ERA and 0.83 WHIP with 34 strikeouts in 29 innings in 2021. He followed up as the Big Ten Conference pitcher of the year in 2022, when the Padres went slightly under slot to sign him for $1.25 million as the 53rd overall pick. Mazur made his professional debut in 2023 in the High-A Midwest League and finished a standout first full year in pro ball in Double-A San Antonio’s postseason rotation.
  
  Scouting Report: Mazur added 10 pounds after signing and could probably still stand to add mass if he’s going to withstand a starter’s workload. His fastball sits 92-96 mph, and his tight slider has been up to 90 mph in becoming a plus power pitch. Mazur also has a mid-80s changeup with two-seam action and armside life as well as a 12-to-6 curveball that keep hitters off-balance. Both breaking pitches fetch swings and misses in and out of the zone. It all comes together out of a loose, easy delivery with a three-quarters arm slot that adds deception to the total package. Mazur also boasts a double-plus ability to fill up the zone. It’s everything you want in a starter. Mazur’s stuff figures to play up even more if he falls into a bullpen role, and the Padres experimented with that look a bit after his promotion to San Antonio while managing his workload in his first full year as a pro. Mazur has projection left in his wiry build.
  
  The Future: The Padres need homegrown options in the upper levels, and Mazur has done nothing but thrive so far in the system. He looks to return to Double-A to build upon last year’s innings base and see if he can indeed develop into a midrotation starter.

  Ranked San Diego Padres #8 prospect in 2023
  BA Grade/Risk: 50/High
  
  Track Record: Mazur logged a 5.50 ERA over two years at South Dakota State, but he began to turn things around with a standout showing in the Cape Cod League after his sophomore year. He transferred to Iowa for his junior season in 2022 and went 7-3, 3.08 with a .178 opponent's batting average, seventh in the nation, en route to winning Big Ten Conference pitcher of the year honors. The Padres drafted Mazur in the second round, No. 53 overall, and signed him for an under-slot $1.25 million. He did not appear in a regular-season game after signing but pitched in instructional league.
  
  Scouting Report: The rare college pitcher who still had physical projection left, Mazur has already added 10 pounds of muscle since signing and has seen his stuff tick up. His fastball sat between 92-94 mph and topped out at 97 during the college season but now touches 99 out of a loose, easy delivery. His slider has jumped to 87-90 mph with added power to become a plus pitch, and his changeup has ticked up to 84-86 mph with enhanced two-seam action and armside life to become an average pitch. He also has an average 12-to-6 curveball he will throw to keep hitters off-balance. Mazur repeats his delivery and three-quarters arm slot well and has made progressive strides with his control. He cut his walk rate from 5.3 per nine innings as a freshman to 4.1 as a sophomore to 2.9 as a junior and projects to have average control.
  
  The Future: Mazur is advanced enough to make his pro debut at High-A Fort Wayne in 2023. He has to prove he can maintain his enhanced stuff over a full season, but he has a chance to be a No. 3 or 4 starter. His plus slider could play in the bullpen if his other secondaries stall.

  The Woodbury, Minn., native began his trek up draft boards last summer while competing in the Cape Cod League. In six starts, Mazur posted a 3-0 record, punching out 34 in 29 innings while only surrendering six walks. He transferred to Iowa from South Dakota State for 2022, and the lanky, 6-foot-3, 175-pound righthander has dazzled this spring. Mazur’s 7-3 record in 15 starts includes 98 strikeouts in 93.2 innings pitched. In a year where Tommy John surgery has cast a cloud over some of the top pitching prospects in the class, the Hawkeye’s ace began to draw bigger scouting crowds with each start, impressing with his pitching maturity and ability to command a four-pitch mix. Mazur’s delivery is a loose, free and easy motion that he repeats well, releasing the ball from a three-quarter slot. Mazur’s fastball sits 92-94 mph and gets up to 97, and he likes to move it around the zone. He pitches inside just enough to keep hitters honest and guessing. Mazur complements his fastball with an above-average offspeed mix that baffles both lefthanded and righthanded hitters. Mazur’s 76-79 mph curveball is sharp and traditional in its break. The 12-to-6 action has frozen its fair share of bats this spring, and it’s a weapon he will use any time in the count. His slider plays well off his curve, as it is similar in shape out of the hand except for the darting three-quarter action that runs away from righthanded hitters. Mazur will mix in a solid-average changeup to lefthanded hitters. It sits in the 82-84 mph range with occasional downward fade. He does have a tendency to slow his arm speed down to take velocity off of it. The results are positive when properly executed, but it may have to be fine tuned at the next level. Mazur has a solid foundation with his command that should only get better. He will have to work hard to add size and strength to his frame. Mazur is expected to come off the board as early as the second round in July. With projection left, scouts believe his best days are ahead and he could move quickly as he adapts to the pro game.
