MLB Draft 2025 Scouting Report For Jamie Arnold to Athletics at Pick No. 11

With the No. 11 overall pick in the 2025 draft, the Athletics selected left-handed pitcher Jamie Arnold out of Florida State.

Ahead is a closer look at what he brings to the table as he starts his pro career, along with a highlight reel and a pro comparison to provide further context for what his future might hold.

Scouting Report

Born: 3/21/2004 (21 years old)
Height: 6'1"
Weight: 188 lbs

Stats: 15 GS, 8-2, 2.98 ERA, 1.06 WHIP, 27 BB, 119 K, 84.2 IP

Left-hander Jamie Arnold entered the spring as the consensus top pitching prospect in the 2025 draft class after going 11-3 with a 2.98 ERA, 1.10 WHIP and 159 strikeouts in 105.2 innings as a sophomore.

That gaudy strikeout total trailed only Chase Burns (191) and Hagen Smith (161), who were the first two pitchers taken in the 2024 draft at No. 2 and No. 5 overall, respectively.

Another step forward this spring might have made him the slam-dunk No. 1 overall pick, and while he ended up putting together a slightly less dominant campaign overall, he is still part of the top tier of college arms and a potential frontline starter down the road.

After working in the upper 80s in high school, Arnold's velocity has climbed considerably during his three years on campus, and he now sits in the mid-90s and touches 97 mph with good late life on his fastball.

His slider is his go-to secondary offering, though he has also shown some feel for a changeup, and Arnold's entire arsenal plays up thanks to a funky, low three-quarters arm slot.

With clean mechanics and a strong track record of throwing strikes and missing bats, the continued development of his changeup could be the final piece of the puzzle for him to develop into an impact MLB starter.

Highlights

Pro Comparison: Chris Sale

A lefty with a mid-90s fastball, plus slider and funky arm slot is always going to draw comparisons to Chris Sale, and Arnold is no exception. However, they have very different builds and Arnold does not have the same arsenal of secondary offerings.

Sale was a lanky 6'6", 180-pounder with durability concerns when he started his pro career, while Arnold has spent two seasons anchoring the Florida State rotation while showing the ability to carry his stuff deep into games.
