For the first time in his MLB career, Merrill Kelly will be testing the free-agent market this offseason. The dependable, middle-of-the-rotation veteran is sure to draw the attention of many teams.
Kelly, who turned 37 last month, is well into the back end of his career. But despite what his birth certificate says, he has continued to be durable while posting strong results.
This past year was indeed one of the better seasons of his career. While still with Arizona, Kelly started 22 games, throwing 128.2 innings to a 3.22 ERA and a 1.057 WHIP.
After being traded to the Rangers at the trade deadline, Kelly had some good starts, but his overall numbers dipped. In 10 starts for Texas, he pitched 55.1 innings, posting a 4.23 ERA with a 1.247 WHIP.
He now hits the open market and should have plenty of appeal from several MLB organizations.
Every team is always looking for more pitching depth. About the time a club feels it has enough, more is often needed.
That is where a veteran arm like Kelly can come into play. Outside of his 2024 season, he has been extremely durable. That year, he made only 13 starts and threw 73.2 innings due to right shoulder inflammation.
So for Kelly to bounce back in 2025 and throw 184 innings while sporting a 3.52 ERA is impressive. It will also serve him and his agent well as they negotiate a new contract for 2026 and perhaps beyond.
Age will play as big a role in what type of contract Kelly gets as anything. Most teams are not going to want to go past two years on the high side for a guy who is 37 years old.
Depending on what the contract ultimately looks like, a third year could be added, but it would have to be at a level that would allow the team to remove him from their roster and still pay him, with it not hurting very badly if his performance really slips.
Kelly is no longer a frontline guy and would slot into the third or fourth spot in a rotation nicely. Tons of teams could use that type of arm to help round out their starters.
With that said, let’s take a look at five teams that seem like they would make the most sense to sign Kelly this offseason.
With the Rangers playing their way into contention heading into the trade deadline, a closer and a bat were the top two needs. When both of those options didn’t materialize, the team did a hard pivot and went after the best available starting pitching in Kelly.

In getting Kelly, the Rangers gave up three solid prospects that included pitcher Kohl Drake, who could be pitching in Arizona in the near future. Trades are great when a team goes on to win, but with the Rangers missing the playoffs, the cost to get Kelly seems even higher.
The Rangers had the best pitching staff in all of baseball last year. And while Jacob deGrom, Nathan Eovaldi, Jack Leiter, Kumar Rocker, Jacob Latz, and Cody Bradford (missed 2025 with injury) will all be returning, they will be missing Tyler Mahle, Patrick Corbin, and even Jon Gray.
With the older guys on the front end of the rotation and the young depth backing that up, Kelly might be a perfect fit to stay in Texas. The two are familiar with each other, and there are worse places to play as a 37-year-old than the air conditioned confines of Globe Life Field.
If there were a championship trophy given for the best team in the regular season, the Brewers would have taken the prize in 2025. Their 97-65 record was the best in baseball.
Much like the Rangers, the Brewers’ pitching was outstanding this past season. They allowed the third-fewest runs, only behind the Rangers and the Padres.
With ace Brandon Woodruff opting out of his contract and the Brewers declining their team option with Jose Quintana, there are going to be some innings that will need to be covered.
Freddy Peralta’s option has been picked up, and there are a ton of top young arms already at the big-league level, including Quinn Priester, Jacob Misiorowski, and Chad Patrick.
But what this Brewers’ team is missing is that veteran presence in the rotation. Someone who can take the ball every fifth day and pitch well into a game, but can also mentor the young guys and help mold them into the pitchers that they need to become.
Kelly would fit that role nicely and could easily slide into the middle of the Brewers’ rotation. The idea of going to a real contender would be exciting for Kelly as well.
Another team that had a good year and great pitching is the Padres. But the team’s rotation is going to look quite a bit different next season.
Nick Pivetta will be returning and will look to repeat his phenomenal year. Randy Vásquez and JP Sears will be back, and Joe Musgrove will be returning from Tommy John surgery at some point into the 2026 season.
That all sounds great, but the subtraction side of the equation is brutal. The Padres are losing both Dylan Cease and Michael King to free agency. Additionally, Yu Darvish will be missing the entire 2026 season after he recently underwent elbow surgery.
San Diego needs innings, and quality ones at that. Kelly would add another veteran to the mix, and someone who is dependable as well as very capable.
With a strong history within the NL West, Kelly could find himself back in that division, but donning brown pinstripes instead of Diamondback colors.
There is a theme with the teams that are on this list up to this point. They have all had really good pitching in 2025, and were either in the playoffs or had a chance up until the last few weeks of the season.
Houston has a new ace, and his name is Hunter Brown. Brown is a finalist for the AL Cy Young award this year and looks to anchor the rotation for years to come.
But behind that, there is a very mixed bag of arms. There isn’t a ton of organiztional depth, and yet they kept putting guys out there last season that somehow got the job done.
The biggest loss for the Astros is coming with the free agency of Framber Valdez. This is a loss, but after the way things unfolded toward the end of the season, it is probably best that the two parties go their separate ways.
Luis Garcia is coming off back-to-back Tommy John surgeries, and Cristian Javier is coming off one of his own.
Kelly would be able to slot into the middle of the Astros’ rotation and would be the workhorse that they will be looking for. And even though they missed the playoffs for the first time since 2016, Houston will be doing what it can to get back to the postseason before their winning window is fully closed.
There is something about playing for your hometown and in front of family and friends on a daily basis. Kelly went to high school in Arizona and later went to college there also.
After stalling out in the Tampa Bay minor-league system, the hurler took his arm and went to the KBO league, where he pitched for four years in his prime.
Making his major-league debut in his year-30 season for his hometown Arizona Diamondbacks was special. After being a steady arm for the club over nearly seven seasons, the team traded him to the Rangers this past year at the trade deadline.
There are other teams listed above that might have a better chance to make a playoff run, but the chance to get back to a familier place close to home might be extremely inticing for Kelly. With a limited salary outlay from Arizona expected, there could be more money on the table from other clubs. But ultimately Kelly could find his way back to the desert.
A reunion of Kelly and the Diamondbacks just makes sense. They know each other well, and the team is going to need some pitching.
Zac Gallen is a free agent, and Corbin Burnes is slated to be back at the All-Star break at the earliest as he returns from Tommy John surgery.
It wouldn’t be surprising if Arizona doesn’t use some of their quality prospect capital and makes a trade for a starter. But seeing Kelly put on a Diamondbacks jersey again and perhaps finish out his career there would still work and be so fitting.
