Dec 2020 Report
Evaluator: Tyler Jennings
Age: 23 yr
Height: 6-2
Weight: 195 lbs
Hits/Throws: L/R
Acquired: 2020 1st
RuleV: 2024
Physical Description: Slender frame at 6'2", 195 pounds with plenty of projection remaining. High waisted with long limbs. Opted to go to Driveline and Cressey Sports Management instead of Cape Cod League after the 2019 season, added 20 pounds of muscle to his lower body and saw improved stuff across the board in an abbreviated 2020. Very competitive.
Delivery & Mechanics: Both the wind-up and stretch feature a high leg kick from the third base side of the rubber. Throws from a three-quarters armslot, pitches down the hill well. Extension is not the greatest and there is some slight effort in his delivery, but creates good deception. Repeats delivery well.
Fastball: With Duke in 2019, Jarvis' velocity range varied between 86 MPH and 92 MPH, but primarily sitting in the high-80's with a drop off as the season progressed. In 2020, Jarvis saw the velocity jump to 92-96 MPH in starts and touching 97 MPH in pre-draft bullpens. The pitch is a low-spin offering (2,100-2,300 RPM), but has a high spin-efficiency and generates good armside life and rise. He's got good command of the pitch and confidence has grown in throwing the pitch in later counts. Velocity during starts has held well, sitting 93-94 MPH late into starts in the spring. Maintaining that throughout a full season will be key for Jarvis. Grade: 60
Curveball: New pitch, but has good feel for it. Sat 77-79 MPH in the spring and has touched 80-81 MPH in bullpens pre-draft. Oft-used, but is an effective pitch. Good shape and depth with spin rates hovering around the 2,200-2,400 RPM band. Could become an above-average offering with more usage and progress. Grade: 50
Slider: Much like the fastball, the slider has seen an uptick in velocity. A low-80's pitch in 2019, it sat in the mid-80's during the 2020 campaign and has touched 88 MPH. The pitch has late break to it that was his primary out-pitch in the spring. It's a high spin offering (2,400-2,650 RPM) with low spin-efficiency. As starts progress, the pitch can get a bit inconsistent, but has good confidence in the pitch. Has a chance to become a plus offering. Grade: 55
Changeup: Arguably Jarvis' best off-speed pitch. Good spread from fastball velocity, as it sits in the mid-80's with great fade to it. The offering has very high spin, averaging close to 2,000 RPM and has touched 2,300 RPM with it. It works great off the fastball, as the spin rates are in a similar band. This causes the pitch to look like a fastball out of the hand. Jarvis has gotten very comfortable throwing the pitch to both righties and lefties. Grade: 60
Control and Command: Jarvis's control improved with the stuff as well. He walked 59 batters in 123.1 innings prior to 2020, but came out and walked just two batters across 27 innings this spring. Whether or not that pans out in a full season is still to be decided, but it gives promise that his control will be an above-average tool moving forward. The command is just as good, as he commands all four pitches very well. Control: 55 | Command: 50
Overall: After having one of the best springs of any college pitcher, Jarvis has proven to be a high-octane arm. He'll be given every opportunity to start with Arizona, likely becoming a backend rotation arm with a chance to become a #3 starter, but that will rely on the sustainability of his new stuff over a full season. Lack of track record brings about some risk. Will be a very interesting follow in this system.
