EDGE Analysis
There had been some buzz that Duplantier could seek a major-league contract after he held a 1.39 ERA and 32.4 percent strikeout rate over 90.2 innings for the Hanshin Tigers in 2025. However, the 31-year-old has opted to continue his career overseas instead. Duplantier last pitched in the majors in 2021.

Duplantier and the Dodgers agreed on a minor-league contract Thursday, Eric Stephen of SBNation.com reports.

The Phillies reassigned Duplantier to minor-league camp Sunday.
EDGE Analysis
A former top pitching prospect in the Arizona system, Duplantier was forced to settle for a minor-league deal with the Phillies this winter after logging a 4.71 ERA and 1.51 WHIP while striking out 109 batters over 93.2 innings for the Dodgers' Triple-A affiliate at Oklahoma City in 2022. He'll likely open the 2023 campaign as a swingman for Triple-A Lehigh Valley.

Duplantier signed a minor-league deal with Philadelphia on Friday, Jon Heyman of the New York Post reports.
EDGE Analysis
Duplantier was also invited to spring training with the Phillies, where he will look to carve a role for himself -- most likely in the bullpen. The 28-year-old righty recorded a 4.71 ERA and 1.51 WHIP through 93.2 innings in Triple-A Oklahoma City last season -- by far the best Triple-A campaign of his career.

Duplantier (lat) has made two relief appearances this season at Triple-A Oklahoma City, striking out four and allowing no hits and one walk over two scoreless frames.
EDGE Analysis
Duplantier, a former Diamondbacks top prospect whom the Dodgers poached from the Giants in the minor-league Rule 5 draft in December, is healthy to start the 2022 campaign. He didn't make any appearances over the final two months of the 2021 minor-league campaign while he recovered from a right lat strain. The Dodgers appear content to develop him as a reliever, hoping that his size (6-foot-4, 229 pounds) and raw skills will allow the 27-year-old to emerge as a potential bullpen option for the big club down the road. Duplantier will first likely have to stay healthy for an extended period before getting a look from the Dodgers.

Duplantier (lat) was selected by the Dodgers in the third round of the 2021 Rule 5 draft Wednesday, JJ Cooper of Baseball America reports.
EDGE Analysis
Duplantier inked a minor-league deal with the Giants late last week, but the team didn't add him to the 40-man roster. While it's not yet clear whether the right-hander's lat strain will keep him sidelined to begin spring training in 2022, he'll remain in the NL West as part of the Dodgers' 40-man roster.

Duplantier (lat) signed a minor-league contract with the Giants on Friday.
EDGE Analysis
Duplantier missed the second half of the 2021 campaign with a lat strain, and it's not yet clear whether he'll be ready to return in time for spring training. He made four starts for the Diamondbacks last year and gave up 19 runs in 13 innings.
