Mariners prospect Ryan Sloan dominant in perfect start for Arkansas

Best one-two tandem in minor-league baseball?

It's hard to argue with the results for the Mariners' top pitching prospects.

One night after Kade Anderson posted another dazzling start for Double-A Arkansas, Ryan Sloan followed with an even better one Saturday.

Sloan, a 20-year-old right-hander, threw six perfect innings against the Frisco RoughRiders in North Little Rock, allowing no runs, no hits, no walks with no errors. He struck out 11.

Sloan was pulled after throwing 61 pitches (46 strikes).

The six innings worked is a career high for Sloan, the Mariners' second-round pick in 2024 out of York High School in Elmhurst, Illinois.

Sloan threw a season-high 74 pitches in an April 18 start.

Anderson, a 21-year-old left-hander, allowed just two hits in 5 1/3 scoreless innings on Friday night, with no walks and nine strikeouts. The No. 3 overall pick in last summer's draft, Anderson has a 1.43 ERA in his first nine pro starts.

Earlier this week, The Athletic's Keith Law ranked Anderson (No. 4) and Sloan (No. 8) among the 10 best prospects in baseball.
