Core Event: Scoreless Innings in Philadelphia
On July 12, 2026, Seattle’s left-hander Kade Anderson and right-hander Ryan Sloan each threw a scoreless inning for the American League in the MLB All-Star Futures Game at Citizens Bank Park. Anderson retired three of four hitters, allowing only a bloop single to Brewers infielder Jesús Made. Sloan followed in the fifth inning, striking out two and working around a two-out double to finish the frame.
Background & Context: Dominance at Double-A
Both pitchers have been dominant for the Double-A Arkansas Travelers, Seattle’s affiliate. Anderson, the No. 3 overall pick in the 2025 draft, posted a 1.36 ERA, 0.69 WHIP and a 108-to-10 strikeout-to-walk ratio over 72.2 innings. Sloan, a 20-year-old second-rounder, logged a 4.11 ERA, 1.19 WHIP and a 72-to-12 K/BB line in 57 innings, adding a sinker to his arsenal. Their performances earned them top-10 overall prospect rankings from MLB Pipeline and Baseball America.
Key Figures & Groups: Profiles and Projections
- Kade Anderson – 6-ft-5, 220-lb left-hander; 2025 No. 3 overall pick; LSU alumnus and 2022 College Pitcher of the Year. Scouts note his deep repertoire and refined changeup.
- Ryan Sloan – 20-year-old right-hander; drafted in the second round of 2025; compared to Gerrit Cole for upside. He tops out at 100 mph, featuring a cutter, sweeper and splitter.
- Seattle Mariners – Possess a deep, healthy rotation (Logan Gilbert, George Kirby, Bryan Woo, Bryce Miller, Emerson Hancock). The club has signaled openness to trading veteran Luis Castillo at the August 3 trade deadline, potentially opening a spot for Anderson or Sloan.
Data & Statistics: Season and Game Numbers
- Anderson: 13 starts, 8-0 record, 1.22 ERA, 99 Ks, 10 walks, .162 opponent batting average.
- Sloan: 13 starts, 2-2 record, 4.11 ERA, 72 Ks, 12 walks, .257 opponent batting average.
- Futures Game: Anderson faced three hitters, allowed one hit; Sloan threw 17 pitches, averaging 98.1 mph on his fastball and recorded two strikeouts.
Why It Matters: Rotation Logjam and Trade Implications
Seattle’s rotation leads the league in innings, WAR and WHIP, leaving limited immediate MLB openings for its top prospects. Front-office sources indicate a willingness to move a starter—most likely Castillo—to address bullpen depth and a left-handed batting need. Should a trade occur, Anderson or Sloan could be the next call-up, a scenario both pitchers acknowledge with patience.
Official Statements & Responses
Anderson emphasized his methodical approach, noting that “having four pitches for strikes has given me a lot of help, and my changeup has come a long way from last year.” Sloan reflected on the organization’s role, saying the Mariners “instill confidence” and have “gotten me to where I am now.” Both expressed a focus on daily work rather than speculation about promotion timing.
Criticism & Opposition
After a spring-game outing where Anderson walked four hitters in two innings, some national writers briefly labeled Sloan the “true ace” of Seattle’s system. Anderson’s subsequent double-A dominance has largely silenced those critiques.
