Diamondbacks Sign Trevor Richards To Minor League Deal

The Diamondbacks have signed right-hander Trevor Richards to a minor league deal, according to his transactions tracker at MLB.com. He has been assigned to Triple-A Reno alongside lefty Anthony Gose, per the southpaw’s tracker. It was reported earlier this week that the Snakes would be signing Gose but it wasn’t clear if it was a major or minor league deal.

Richards, 32, has had some major league success but has been in poor form for about a year now. The Blue Jays dealt him to the Twins at last year’s deadline but Richards lasted only 13 innings with Minnesota before being outrighted off the roster. In that time, he walked 11 opponents, a rate of 18.6% of batters faced. He also hit two other batters and issued seven wild pitches.

Here in 2025, he has signed minor league deals with the Cubs and Royals, getting a brief look in the majors with the latter club. He has thrown 19 1/3 minor league innings this year with a 4.19 earned run average, 25.6% strikeout rate and 13.6% walk rate. In his quick major league stint with Kansas City, he allowed four earned runs in three innings.

Prior to those struggles, he had a good run in the big leagues. He tossed 201 innings over the 2021-23 seasons with a 4.61 ERA, 31.3% strikeout rate and 10.9% walk rate. He earned one save and 25 holds in that time.

The Arizona bullpen has taken a few punches this season. The relief group was supposed to be anchored by A.J. Puk and Justin Martínez but both are currently out of commission. Martínez recently required Tommy John surgery and will be out for the year. Puk is on the IL with a flexor strain and was recently shut down due to some renewed discomfort. In addition to those two, Kendall Graveman and Christian Montes De Oca are also on the IL.

Amid those injuries, the club’s bullpen numbers are unsurprisingly poor. Arizona relievers have a collective 5.39 ERA, which puts them ahead of only the Nationals and Athletics. If they stay in the playoff race, adding relievers will surely be a deadline focus. For now, they’ll take chances on guys like Richards and Gose while hoping for the best.
