Background
Sims developed his craft as a right-handed pitcher growing up in Lawrenceville before signing with the Cincinnati Reds organization. He worked his way through the minors steadily and reached the majors in August 2017 — the start of a journey that would take him through several MLB uniforms. Since then, he has focused on cementing himself as a reliable arm out of the bullpen, adapting to whatever role a pitching staff needs.
Professional Career
Sims has suited up for the Cincinnati Reds, Philadelphia Phillies, Washington Nationals, and Chicago White Sox, working almost exclusively as a reliever throughout his career.
His strongest recent stretch came in 2024, when he posted a 4.38 ERA with 49 strikeouts in 49.1 innings — solid production despite a 1-6 record. The 2025 season in Washington was a rougher ride: a 13.86 ERA in 12.1 innings, though he still managed to rack up 13 strikeouts. He bounced back in 2026 with the White Sox, trimming his ERA to 4.50 over 10 innings and showing the kind of resilience that has kept him in professional baseball for nearly a decade.
