Daulton Jefferies Talks Pitching (Look Ma, No Seams)
When Eric Longnhagen wrote up Daulton Jefferies for last year’s Oakland A’s Top Prospects list, he cited a “plus, upper-80s changeup and plus command” as the now–25-year-old right-hander’s primary attributes. That combination helped earn Jefferies a cup of big-league coffee last September, and it has him projected as a member of Oakland’s starting rotation for the upcoming season.
Drafted 37th overall out of Cal-Berkley in 2016 — he underwent Tommy John surgery that same year — Jefferies is atypical among young, modern-day pitchers in that he stands just six-foot (and weighs 195 pounds) and is neither data-savvy nor a flamethrower. His fastball sits a relatively pedestrian 93–95 mph, and the spin rates on his array of pitches remain a mystery to him. Then there is the strangest thing of all: Jefferies features a no-seam repertoire.

David Laurila: What is your full repertoire, and what is your best pitch?
Daulton Jefferies: “I have four- and two-seam fastballs, a changeup, a slider, and a cutter. My best pitch is my changeup.”
Laurila: What makes it effective?
Jefferies: “I think it’s more of a tunneling thing. You want everything to look like a fastball for as long as possible — Gerrit Cole does that really well, [Jacob] deGrom, [Max] Scherzer, all those guys — and mine has good depth. It’s also really hard; it’s like 87 to 90 [mph] and I can run it up to 90 at times. The only time I get in trouble is when it flattens out and basically becomes a straight fastball. Most of the time, it’s my go-to pitch, right-on-right. It’s my baby.” Read the rest of this entry »
