Notes

2/29/24

It was an outing to remember from the 6-foot-0, 205-pound Appling County ace. Griffis went six strong innings, allowing just one hit while punching out 15 against West Laurens. The Tennessee showed excellent pitchability mixing a quality three-pitch with confidence with heavy swing-and-miss in the process. Fastball lived 89-91 on a chilly, touching 92 twice with hard, late arm-side life that was getting on top of hitters quickly for in-zone misses. Griffis had the ability to throw the fastball in any count with positive results throughout. Slider feel continues to grow at 75-77 with sharp, late sweep and some feel to spin. Ability to manipulate sweep in two-strike counts at times for ugly chase. Improved splitter in the mid-70s was a go-to for Griffis, especially early in the count and created good swing-and-miss due to heavy fade from the same fastball tunnel. Standout performance from Griffis all-around, and looked one of the best pitchers in South Georgia.

GA Preseason All-State

Dayson Had one of the most impressive event performances in recent memory. After standing (not sitting) through 35 bullpens in the rain and cold, it was time for the Appling Animal to toe the rubber. With his stocky frame, Kenny Powers-like hair, and a towel in his back pocket to dry off the ball, he was ready to go. The rain had gone from mist to pouring, and his FB is sitting 90-91 with serious bore that will undoubtedly dominate hitters all spring. He cruised in that range until the last two pitches. Then he said, “Be ready for these catch.” Griffis proceeded to throw two pitches back to back at 93.5 and 93.7 that moved at the speed of an actual missile. I’ve never seen a player this age who can just reach back for 2 more mph on command. This isn’t normal. Despite unreal physical strength (315 power clean), Dayson has a very low effort delivery and is an efficient mover. The pace builds gradually from the windup - slow to square up, medium through up+down+out phases, and fast (controlled violence) post landing which is a big reason his delivery is so effortless. It's an advanced lower half with elite backside connection in stride. He creates power from the ground up by putting all the pressure on his legs, and holding his upper half over the rubber during stride.
The arm action is a mid depth, full circle with an efficient arm spiral. Compact yet smooth, a great combo to have in a delivery. He’s also a closed foot lander who rotates on the ball of his feet - causes more acceleration in the kinetic chain & leads to more violent rotation (clearance) post landing into lead leg block. This is a trait that many high velocity arms have in MLB. These traits are undoubtedly helped by playing QB (3AA Offensive Player of the Year) for Appling. Playing QB and throwing hard on the mound are an often occurrence in top prospects across the country.

GA Preseason All State

Griffis showed not only how much bat strength he has, but also how well sequenced and timed up the swing is. He’s very quiet and simplified, so its not just strength being the reason he controls his body so well. His hands are pre set into launch position with almost unnoticeable rhythm in his hands, but there is rhythm. Griffis has a very short stride with his toe and the load is minimal with just a slight rise of the hands allowing him to get in a powerful position for the knob to lead the path. He matches plane extremely well and has a very compact, direct path to the ball. Dayson creates intense lag in the barrel and his hands are extremely balanced throughout the path, getting barrel angle last second. His 96.2 EV was one of the higher recorded in the event, where he showed loud pull side power. Dayson also ran a 6.96 in a ridiculously strong, stocky frame. With innate instincts, smooth hands, and a rocket arm (94 mph) Griffis is a legit two way prospect and one of the most exciting players in the 2025 class.

8/20/20

Griffis was the lone non-Floridian on our JFG squad. The Georgia native made a big impact for his team. During the workout he showed power putting several balls over the fence. He led the team with the highest exit velocity off the tee at 89 mph. During the games, he led the team with 9 hits, 3 being extra base hits. On the mound, Griffis showcased a fastball up to 84 mph.
