  Scouting Report & Links      
         
  Physical Description: Medium-sized, filled-out frame. No projection. Thick lower half.

Mechanics: Throws from a low three-quarters arm slot. Starts on the third base side of the rubber. Effort in delivery. Slings the ball and lands off-line, towards third base, on occasion.

Fastball: 92-94 mph. Topped out at 97 mph in the past when he threw over-the-top. Late sinking movement. Can flatten out when arm tires. Command and control are lacking and need refinement.

Slider: 82-84 mph. Long, sweepy breaking ball. Will front door it to left-handed hitters and bury down and away from right-handers. Has shown the ability to miss bats at the minor league level. Potential average offering.

Changeup: 83-85 mph split changeup. Inconsistent pitch.

  Career Notes: Drafted by Oakland in 2007 but opted to attend Arizona St. Pitched for Cotuit in the Cape Cod League in 2009. One of the top pitchers in college baseball in 2010 before becoming a first-round comp pick for the Cardinals. Suspended for the post-season in 2011 for violation of team rules. In April 2012, he was diagnosed with enchondroma, a benign tumor on his pitching hand. Had surgery, resulting in a loss of control. Released following the 2014 season and subsequently retired. Returned to baseball in 2019. Built a training facility in his backyard during COVID-19 shutdown, which 15 pro prospects attended at various times. Rebuilt his mechanics to throw sidearm and was signed by Boston, pitching at the Alternate Training Site. Opened 2021 season at Alternate Training Site.

Summation: Potential organizational relief arm. Ceiling of an up-and-down, emergency reliever. How his command and control develop will determine whether he can make the next step up to the major league level.
