Uncommitted, Robertson tossed eight total innings on the week striking out 13 batters and allowing a hit. The freshman did struggle with walks throughout the week, giving out 10 free passes in that span.
Mason Robertson, Martin Luther (WI), 2027
Positional Profile: LHP/OF
Body: 5-7, 138-pounds. Wiry build, athletic proportions, will add size and strength.
Delivery: Controlled tempo, gets into his lower-half with a drop/drive stride, works in-line with the plate, athletic finish.
Arm Action: LH. Long, loose arm action, high 3/4 release.
FB: T81, 79-81 mph. Forward life finish with good touch and feel to get the ball to spots. T2007, 1916 average rpm.
CB: 66-68 mph. 12/6 shape and break, sharp, can land and get below. T2102, 1964 average rpm.
CUT: 71-75 mph. True slider, lateral, late, sharp with good tunnel out of hand.
SPLT: 70-72 mph. Late downer at the plate, weapon, nasty.
ATH: 7.12 runner in the 60. 24.30 max vertical.
The lefty controls his tempo, working in-line to home plate with a drop-and-drive stride into an athletic finish. It’s a long, loose arm that works into a high 3/4 release. The freshman sat 79-81 mph, hitting 81.5 mph with his fastball and setting up a curveball at 65-68 mph. He also went to a true cutter, playing with short lateral bite at 70-74 mph to give a different look. His final offering was a splitter with late downward action at times, playing below the zone at 70-72 mph.
OF/LHP Mason Robertson (Martin Luther, 2027) is a lanky, athletic 5-foot-8, 140-pound player, who was floating around the outfield confidently with athleticism. The left/left prospect sprays line-drives around the diamond with loose hands/wrists that create bat speed. Roberston took a smooth round of BP and defense where his tools were on display. The twitchy two-way will look to impress this week at the biggest event of the summer at LakePoint this week.
Mason Robertson, Oak Creek (WI), 2027
Positional Profile: LHP/OF
Body: 5-8, 140-pounds. Sloped shoulders with high waist, projectable.
Delivery: Easy, repeatable mechanics. Drop and drive delivery.
Arm Action: LH. Loose, easy arm. Medium arm arc into 3/4 slot..
FB: T75, 70-74 mph. Some life to the arm side.. T1734, 1454 average rpm.
CB: 60-62 mph. Short 1/7 action. T1979, 1854 average rpm.
SL: 60-63 mph. Short 1/7 action T2002, 1913 average rpm.
ATH: 7.79 runner in the 60. 1.94 in the 10 yard split.
Mason Robertson, Oak Creek (WI), 2027
Positional Profile: LHP/OF
Body: 5-8, 140-pounds. Sloped shoulders with high waist, projectable.
Hit: LHH. Starts in a balanced with relaxed hands. Short stride, smooth loading actions. Direct, attacks from above the ball, back spins the ball through the middle of the field.
Power: 84 max exit velocity, averaged 63.4 mph. 252' max distance.
Arm: LH.
ATH: 7.79 runner in the 60. 1.94 in the 10 yard split.
LHP/OF Mason Robertson (Oak Creek, 2027) is a loose projectable athlete who stands 5-foot-8, 140-pounds with plenty of room to fill out. He showed off his feel for the barrel by consistently driving balls through the middle of the field with a quick handsy swing. His exit velocities registered in the mid-80 mph range. On the mound, the left-hander works with a loose and repeatable delivery with a fastball in the mid-70s and showed the ability to drive balls through the glove. He has a couple of different breaking balls with his slider and curveball which both show solid shape and lateness to their break.

Robertson got the nod for Hitters White in their first game of the 13U PBR at The Rock Summer Championships. At 5-foot-7, 125-pounds, Robertson is a clean mover on the mound as he organizes well in his delivery to produce fastballs up to 73 mph. He also showed feel for a 1/7 breaker to keep hitters off balance and one with the makings of a sharp breaker in the future. Robertson finished his start with seven strikeouts and just one earned run on three hits in his four innings of work.
