The Yokohama DeNa Baystars of Japan’s Nippon Professional Baseball are going to post left-hander Shota Imanaga this offseason, reports Jon Morosi of MLB.com. The southpaw will be eligible to explore opportunities with clubs in Major League Baseball as a free agent, though any club that signs him would owe a posting fee to the Baystars.
Imanaga is a veteran in Japan, having just turned 30 years old on September 1. Over eight seasons, he has tossed 977 innings with a 3.18 earned run average while striking out 24.9% of batters faced and walking 6.9%. He’s been ever better this year, with a 2.72 ERA over 122 1/3 innings, along with a 29.1% strikeout rate and 3.9% walk rate. He also pitched for Japan in the World Baseball Classic earlier this year, allowing two earned runs over six innings.
Here at MLBTR, Imanaga has been featured on all four editions of our NPB Players To Watch series, coming in at #3 in the first edition but #2 on each subsequent update. As noted by MLBTR’s Dai Takegami Podziewski in the first of that series, Imanaga doesn’t have an overpowering fastball but finds success thanks to his command and gets strikeouts with his changeup, which is close to a splitter. He also has a cutter, a curveball and a slider. He signed with the U.S.-based agency Octagon to help talks toward a posting agreement last offseason.
Once Imanaga is formally posted, there will be a 30-day window where MLB clubs can negotiate with his representatives. If a deal is reached, the signing team will also owe money to the Baystars, with that amount being relative to the size of the contract given. Any big league team that signs him would owe the Baystars a fee equal to 20% of the contract’s first $25MM, 17.5% of the next $25MM and 15% of any dollars thereafter. If he does not reach an agreement with an MLB team, he will return to the Baystars for 2024.
When he hits the market, Imanaga will add another interesting arm to a free agent class that is heavy on pitching. Another NPB star, Yoshinobu Yamamoto, is expected to be in the mix, alongside other pitchers like Aaron Nola, Blake Snell, Lucas Giolito, Jordan Montgomery and Sonny Gray, while pitchers like Eduardo Rodriguez and Marcus Stroman have opt-outs and could jump into the mix as well.




Bader, 29, and Renfroe, 31, were two of several veteran players placed on waivers this week. There were many clubs who were still hovering around contention at the trade deadline but slipped back in the standings in the month of August. But the opportunity to trade impending free agents for any kind of return had passed by, leaving them little recourse but to place those players on waivers. By doing so, they could perhaps at least save themselves some money since the claiming team takes on the remainder of the contract, while allowing the player to move somewhere with a chance to contend and perhaps make the playoffs.
Despite each player’s value, the Yankees and Angels fell back in the standings in August and gave up on their hopes of contending. Both of these players are impending free agents and neither would warrant a qualifying offer at season’s end, so their respective clubs placed them on waivers in the hopes that another team would put in a claim and take the remainder of the contract off their hands.
