Munetaka Murakami came into the offseason as one of the more intriguing names on the free agent market. He slotted in at No. 4 on our annual Top 50 MLB Free Agents list. Despite Murakami’s prolific power in NPB, the reported interest around the young slugger was minimal as the winter progressed. The White Sox and Red Sox were among the only known suitors. Murakami ultimately went to Chicago on a modest two-year, $34MM deal.
The Diamondbacks were among the teams interested in Murakami, reports John Gambadoro of 98.7 Arizona Sports. Gambadoro added that the former Japanese star was “one of a few of the Asian players” the Diamondbacks were considering. He didn’t mention any other names, but the free agent market includes several notable players making the jump stateside, including Tatsuya Imai and Kazuma Okamoto. MLBTR’s Anthony Franco predicted Okamoto would sign with Arizona in the aforementioned Top 50 FAs piece.
Arizona’s connection to Murakami makes sense given the state of the club’s corner infield spots. First baseman Josh Naylor and third baseman Eugenio Suarez were dealt to Seattle in separate deals at the trade deadline. That left Pavin Smith and Tyler Locklear (who came over in the Suarez trade) to handle the majority of the first base reps. Blaze Alexander stepped in as the primary third baseman.
Top prospect Jordan Lawlar is slated to step in at the hot corner in 2026, but first base is a question mark. Locklear had surgery on both his left elbow and shoulder in October. He’s a candidate to begin the season on the injured list. That leaves Smith and utilityman Tim Tawa as the current options at first base. Arizona finished with the 5th-lowest OPS at the position last season. With Murakami off the board, the club could look to pursue at least a right-handed complement to Smith, and perhaps an upgrade altogether.
On the pitching side, Gambadoro mentioned he expects the team to look into the closer market. Arizona will be without top closers Justin Martinez and A.J. Puk for the majority of the season. Both relievers had Tommy John surgery in June. The current closer mix is an uninspiring group that includes Andrew Saalfrank, Ryan Thompson, and Kevin Ginkel.
Arizona’s bullpen ranked 25th in xFIP and 28th in SIERA last season. The club had a whopping 17 pitchers record saves in 2025. Shelby Miller led the way with 10 saves. He was dealt to Milwaukee at the trade deadline. The Diamondbacks had four saves in the final month of the season, and they went to four different pitchers (Jake Woodford, Taylor Rashi, Kyle Backhus, John Curtiss).
Martinez and Puk won’t be out forever, so Arizona doesn’t need a long-term solution. The reliever market is beginning to thin out, but there are still a handful of options with closing experience available. Seranthony Dominguez, Ryan Pressly, or Chad Green could make sense as short-term closers who have been setup men in the past. Arizona’s Opening Day closer will likely slot in behind Martinez and Puk once they return, so experience in the 7th and 8th innings would be useful.
Elsewhere in the NL West, former Giants infielder Jae-gyun Hwang announced his retirement (h/t to J.P. Hoornstra of The Big Lead). Hwang had spent the last eight seasons with the KT Wiz of KBO. He’d been in professional baseball since 2007.
Hwang made the jump to MLB in 2017 after a decade in KBO. He signed a split contract with the Giants in January that year. Hwang posted decent results in Triple-A, hitting .285 with 10 home runs and seven steals across 98 games. He was up and down a couple of times with the big-league club, with unimpressive results. Hwang went 8-for-52 in 18 games with the Giants. He did launch a home run for his first MLB hit, taking Kyle Freeland deep in his third career at-bat.
Hwang was outrighted off the 40-man roster in September 2017. After his lone season with the Giants, the Wiz lured him back to KBO with a four-year, $7.9MM deal. He was a well-above-average hitter for the duration of the agreement and remained productive at the plate for the rest of his career, including a 94 wRC+ as a 37-year-old in his final season.
We at MLBTR wish Hwang the best in his future endeavours beyond baseball.
