Sloan, a second-round pick in the 2024 draft, made the leap<\/a> from being ranked 60th to 22nd league-wide and also moved in front of left-hander Kade Anderson as the second-ranked prospect in the Mariners\u2019 organization. Colt Emerson, who signed an eight-year, $95 million extension with the M\u2019s last week, remained as the organization\u2019s top prospect.<\/p>\n Here\u2019s what Baseball America had to say about Sloan after his massive jump in the rankings.<\/p>\n Sloan was excellent in 2025, which saw him dominate the Class A levels before eye surgery ended his season. He\u2019s so far taken his game up another notch in 2026, performing as the star of the Mariners\u2019 Spring Breakout game and earning a jump to Double-A. He\u2019s got power, pitchability, a physical frame and a repeatable delivery. All those variables should add up to a fixture in a rotation full of homegrown success stories.<\/p>\n Though he only pitched in one Cactus League game, striking out one in one scoreless inning of relief, the 6-foot-5 Sloan drew rave reviews during Mariners camp<\/a>. He showed a glimpse of why during the Spring Breakout game against the Milwaukee Brewers\u2019 top prospects, tossing three perfect innings on 39 pitches while striking out three batters.<\/p>\n Sloan, 20, posted a 3.73 ERA with a 1.16 WHIP, 90 strikeouts and 15 walks over 82 innings in 21 starts across Single-A and High-A last season. After making just three starts with High-A Everett last year, he began this year with Double-A Arkansas, making his Travelers debut on Saturday night.<\/p>\n In Sloan\u2019s first Double-A action, he struck out four and allowed three runs on five hits and one walk over four innings of work.<\/p>\n<\/p>\n In addition to Sloan being the biggest riser in Baseball America\u2019s updated prospect rankings, outfielder\/second baseman Michael Arroyo was among seven players who joined the top 100<\/a>. Arroyo, who had been ranked in Baseball America\u2019s top 100 last year, checked in at No. 100.<\/p>\n The 21-year-old Arroyo slashed .262\/.401\/.433 with 17 homers, 24 doubles, one triple, 69 walks and 104 strikeouts over 121 games across High-A and Double-A last season. After playing 56 games in Double-A in 2025, he rejoined Arkansas to begin this season.<\/p>\n Arroyo hit his first homer of 2026 and played his first minor league game as a left fielder on Friday night.<\/p>\n<\/p>\n Former Mariners catching prospect Harry Ford, who was traded to the Washington Nationals<\/a> in a deal that brought left-handed reliever Jos\u00e9 A. Ferrer during the offseason, was one of two players who dropped out of the top 100.<\/p>\n Here\u2019s where the five Mariners who made Baseball America\u2019s new top 100 ranked, plus how far they rose or dropped from the previous January rankings.<\/p>\n \u2022 No. 7 Colt Emerson, no change Seattle Mariners coverage<\/p>\n \u2022 Watch: Brendan Donovan homers on 1st pitch vs Rangers<\/a>
