Diamondbacks Designate Veteran Reliever Paul Sewald for Assignment

8/11/2026, 12:17:59 AM

Core Event

On August 10, 2026, the Arizona Diamondbacks designated right-hander Paul Sewald for assignment, as reported by Arizona Sports 98.7 FM host John Gambadoro. The move removes the 36-year-old from the 40-man roster and makes him available on waivers. Earlier reports listed the transaction as occurring on August 5, 2026, creating a minor date discrepancy.

Background & Context

Sewald joined Arizona at the 2023 trade deadline, recorded 13 saves that season, and re-signed for 2024. After stints with Cleveland and Detroit in 2025, he returned on a one-year, $1.5 million deal for 2026. He has 110 career saves across ten seasons with several clubs.

Data & Statistics

  • Early 2026: Through June 19, Sewald posted 18 saves with a 3.18 ERA in 28.1 innings (CBS Sports: 3.08 ERA, 0.72 WHIP).
  • Mid-season decline: After June 23 he gave up 18 runs and seven homers in 14 games, inflating his ERA to 14.34 (Athlon). He finished the season with 24 saves in 45 appearances, a 6.23 ERA and a 5.68 FIP.
  • Season totals: Heavy reports a 2-5 record, 6.23 ERA, 34 hits allowed and a WAR of –1.1 over 39.0 innings.

Official Statements & Responses

John Gambadoro announced the DFA. Manager Torey Luvullo has not named a permanent replacement, continuing a “closer-by-committee” that has featured left-hander Brandyn Garcia. Reports suggest the club may add right-hander Zack Littell to the 40-man roster, while Michael Soroka is expected to return without occupying a slot.

Why It Matters

At the time of the move, Arizona was 63-56, 7½ games behind the NL West leader and tied for the second wild-card spot. Sewald’s 6.23 ERA placed him among the league’s least effective relievers, prompting the roster change to stabilize late-inning options as the team pursues a postseason berth.

Conflicting Reports & Gaps

  • Date of designation: Some sources cite August 5, 2026, others August 10, 2026.
  • ERA after June 23: Athlon lists a 14.34 ERA for that stretch, while Heavy and SI give a season-long 6.23 ERA, reflecting different calculation windows.
  • Future bullpen plan: Littell’s signing is reported, but the club has not confirmed who will assume the primary ninth-inning role.

What’s Next

Sewald’s one-year, $1.5 million contract makes him eligible for waiver claims. If he clears waivers, he can reject an outright assignment and become a free agent. Arizona will focus on finalizing its bullpen—potentially adding Littell and evaluating internal options such as Taylor Clarke, Kevin Ginkel, Jonathan Loáisiga, Juan Morillo and the returning Justin Martinez—while maintaining its push for a wild-card spot.
