Just weeks after right-hander Joel Kuhnel posted a stellar 1.84 ERA across 14 appearances, his season-long ERA dramatically jumped to 4.21 following a single disastrous outing against the Chicago Cubs, according to Reviewing the Brew. This significant statistical shift preceded his trade to the Milwaukee Brewers for cash considerations on June 6, 2026, according to MLB Trade Rumors.
Kuhnel demonstrated elite bullpen potential early in the season, but that solitary poor appearance against the Cubs, where he allowed four earned runs in just two-thirds of an inning, dramatically altered his statistical profile and led directly to his designation for assignment by the Oakland Athletics.
The Milwaukee Brewers are therefore acquiring a reliever with significant upside at a minimal cost, capitalizing on the Athletics' swift decision. His immediate impact on the Brewers' bullpen, however, remains uncertain given his recent performance volatility.
Who is Joel Kuhnel?
- Joel Kuhnel maintained a 1.84 ERA through his first 14 appearances out of the Athletics' big-league bullpen this season, according to Reviewing the Brew.
- Kuhnel's season-long ERA rose from 1.84 to 4.21 after he allowed four earned runs in two-thirds of an inning during a game against the Chicago Cubs, as reported by Reviewing the Brew.
These figures illustrate Kuhnel's dual nature: a pitcher capable of suppressing runs effectively for extended periods, yet prone to singular, high-impact failures. Kuhnel's volatility suggests he represents a high-risk, high-reward bullpen asset, rather than a consistently reliable option.
The Transaction Details
The Oakland Athletics designated right-hander Joel Kuhnel for assignment on June 5, 2026, according to mlb. The designation for assignment occurred just one day after his ERA ballooned from 1.84 to 4.21, suggesting an organizational priority on immediate statistical optics over a player's broader performance trajectory.
