For all intents and purposes, the Milwaukee Brewers’ Shelby Miller trade was a bust. Arizona’s co-closer was supposed to give the bullpen another-high leverage arm for the rest of the season. Instead, he gave the Brewers 11 games before sustaining a year-ending elbow injury.
The most regrettable misfortune, of course, is to Miller himself. He already has one Tommy John surgery under his belt; now he’s likely to need another. Set to turn 35 shortly after the season ends, the 13-year veteran has only so much gas left in the tank.
He did, at least, get some positive news during the series in Texas. It won’t impact the Brewers, but it’s good to hear that Miller could be back sooner than anticipated.
Typically, pitchers take 12 to 18 months to recover from Tommy John. Based on the diagnosis Miller received from a Texas doctor, the Round Rock native may be looking at close to a minimum length absence. Via team reporter Adam McCalvy:
Shelby Miller said he had an encouraging visit here in Texas with Dr. Keith Meister. He’ll undergo surgery at some point, but the hope right now is that it won’t be a full UCL repair. That would leave open the possibility of a late-season comeback in 2026.

For the Brewers, the relationship is likely over. Miller will be a free agent this offseason and still in recovery when spring training rolls around. If he signs somewhere before the end of next season, it should be closer to his eventual return. A team in need of bullpen depth could take a flyer on Miller, or offer him an opportunity by way of a minor-league contract.
The Brewers themselves gave up nothing to get him. Essentially, they acquired Miller in exchange for absorbing the contract of injured starter Jordan Montgomery, which they had room to do after dumping Nestor Cortes. Montgomery simply moved from Arizona’s 60-day injured list to the Brewers’. Otherwise, they acquired Miller for pennies on the dollar: cash or a player to be named later.
He, too, was injured at the time of the trade, helping to explain his low market value. Maybe the Brewers knew it was a buyer beware situation. His forearm strain in Arizona has been linked to the same issues that caused his season-ending elbow “pop” in Milwaukee. After delivering the fateful pitch, he began shaking his arm immediately and left the game without facing another batter.
Still, the Miller addition was worth a shot. Before hitting the injured list, he showed plenty of juice with the Diamondbacks, posting a 1.98 ERA and 9.9 K/9 rate in 36.1 innings. Post-injury, although effective at times, he never quite found his groove in a Brewers jersey. In nine and two-thirds, Miller struck out 14 but allowed six earned runs and a pair of homers.
A starter turned reliever, Miller is 51-69 lifetime with a 4.04 ERA in 921.2 IP. Of his 13 career saves, 10 came this season in Arizona.
