Prep Baseball Report Oklahoma hosted the second annual Summer Underclass Games at the University of Oklahoma on Wednesday, May 30th. The event showcased a completely sold out event of 65 players from the 2020 and 2021 grad classes in two sessions. Each position player went through a pro-style workout followed by a game where pitchers threw live. 

This talented underclass event saw big numbers put up across the board. There were 17 60s under 7 seconds, nine exit velos 90 mph or better, five pitchers above 85 mph, four catchers pop 2.00 or better, and an infielder who hit 90 across the diamond.

Today, we will take an in-depth look at the left-handed pitchers from the event. Though many are talented two way players, they will be covered here as pitchers only with positional analysis to follow.

Jordan Brewer LHP / OF / Choctaw , OK / 2020

A proportional 6-foot-2, 187-pound frame. On the mound, the left-hander works only from the stretch with a moderate leg kick before striding straight down the mound and finishing towards the dish. Arm action is long in the back with a quick change of direction at the bottom of his arm stroke before coming through a high-¾ slot. Fastball was not as firm as we have seen it before, sitting 82-84 mph with occasional heavy arm side run, mostly strikes. Slider has depth at times, occasionally spinning out, 73-74 mph with 1/7 shape. Changeup is thrown with full arm speed at 77-78 with some fade. In the game, Brewer struck out four of the five batters he faced and allowed one hit. 

Dillon Bumgarner LHP / 1B / Calera, OK / 2020

A 6-foot, 130-pound long, lean, and projectable frame. On the mound, the left-hander works from an average tempo delivery with a moderate leg kick and a slight hitch before striding to the dish. Arm action has moderate length as he drops the ball straight down out of the glove before making a smooth circle and bringing it through a 3/4 slot. Fastball ranged 70-74 with consistent arm side run. Breaking ball has east-west movement at 58-59 mph. Changeup shows fade and sink at 59-60 mph. Fills up the strike zone with all three pitches. In the game, kept hitters off balance with deception, movement, and location. Did not allow any hard contact.  

Dondi King Jr. LHP / OF / Edmond Santa Fe, OK / 2021

A 6-foot-1, 180-pound athletic frame. On the mound, the left-hander works from an average tempo delivery with rhythm using a high leg kick and a soft front side before finishing to the dish. Arm action has length dropping straight down and behind him with a hitch before coming through an over the top slot with some stiffness. Fastball sits 74-77 mph with consistent and late arm side run. Curveball shows big depth with near 12/6 depth at 65-67 mph. Changeup has some depth 67-68 mph. Filled up the zone with all three pitches. Punched out three of the five batters he faced and got weak contact from the other two.

Cooper McMurray 1B / LHP / Bishop Kelley , OK / 2020

A physically advanced 6-foot-3, 220-pound frame with strength. On the mound, the left-hander works from a controlled tempo with a short leg kick and a short front side before finishing directly to the dish. Arm action has moderate length in the back with looseness before coming through a high-¾ slot. Fastball sits 79-80 mph with some arm-side run. Curveball has big 1/7 shape at 67-68 mph. Changeup is thrown with full arm speed with excellent fade at 71-72 mph. In the game, McMurray punched out three of the five batters he faced and only gave up one hit, filling up the strike zone with all three pitches. 

Colby Routh 1B / LHP / Edmond Memorial, OK / 2020

A 6-foot, 175-pound frame with room to add size and strength. On the mound, the left-hander works from a slightly up-tempo delivery with rhythm and a high leg kick that he repeats very well. Arm action is long, fluid, and loose in the back before coming through a high-¾ slot with quickness. Fastball sits 81-83 mph with occasional cut to the glove side and run to the arm side. Curveball shows big 1/7 shape at 63-64 mph. Changeup has good fade and late sink with deception. In the game, Routh threw almost every pitch where he wanted striking out four of the five batters he faced and never throwing more than one ball to any batter. 

Seth Stacey LHP / 1B / Tahlequah, OK / 2020

A broad shouldered 6-foot-1, 198-pound frame with strength. On the mound, the left-hander works from a slightly uptempo delivery with a moderate leg kick.

Fastball ranges 79-83 mph with some downhill tilt and occasional arm-side run. Curveball has rolling action at 59-60 mph. In the game, got weak contact and had the occasional big miss. An arm to watch has he develops body control.
