Diamondbacks Designate Seth Martinez For Assignment

The Diamondbacks announced that right-hander Seth Martinez has been designated for assignment. That’s the corresponding move for their signing of fellow righty Kendall Graveman, which is now official.

Martinez, 30, has never suited up for the Snakes. He was just claimed off waivers from the Astros in November, shortly after the World Series. He lasted on the roster through most of the winter but has been nudged off today.

All of his major league experience has been with Houston thus far. He was added to that club’s roster late in 2021 and spent several years as a fringe member of the bullpen, getting optioned to the minors 12 times since getting that roster spot.

Around those trips on the shuttle, he tossed 137 1/3 major league innings for the Astros, allowing 3.93 earned runs per nine. His 20.7% strikeout rate, 9.2% walk rate and 39.6% ground ball rate to this point are all close to average but a bit worse than the mean. He also tossed 105 minor league innings over the past four years with more intriguing numbers. He had a 2.66 ERA in that work, along with a 31.5% strikeout rate and 10% walk rate.

He exhausted his final option year in 2024, which means he’ll be less valuable from a roster flexibility standpoint going forward. That likely played a role in the Astros bumping him off their roster. The Diamondbacks were presumably intrigued enough by his minor league strikeouts to claim him and hang onto him for a while but he’s been squeezed off a roster yet again.

Martinez will now be in DFA limbo for a maximum of seven days. He will likely be put back on waivers, which is a 48-hour process, so the Diamondbacks could explore trade interest for the next five days. If any club acquired Martinez, he has a bit more than two years of service time, meaning he still hasn’t qualified for arbitration and can be theoretically controlled for four seasons. However, his aforementioned out-of-options status will give him a bit of a challenge in sticking somewhere.
