TOKYO -- Pitcher Masahiro Tanaka wants to move to Major League Baseball next season, but his Japanese team doesn't want to let him go.

MLB and Nippon Professional Baseball have finalized a new posting system that caps the fee for players at $20 million, much less than what Japanese teams previously got for players such as pitchers Yu Darvish and Daisuke Matsuzaka.

"I informed my team that I would like them to allow me to test my abilities in Major League Baseball next season," Tanaka said at a news conference on Tuesday after a meeting with Rakuten Eagles President Yozo Tachibana.

Tanaka, a 25-year-old right-hander, went 24-0 with a 1.27 ERA with the Rakuten Golden Eagles of the Pacific League during the regular season. He will not become eligible for free agency until after the 2015 season and can move to MLB only if the Eagles agree to post him.

The Eagles, who won the Japan Series, voted against the new posting agreement in balloting by Japan's 12 teams on Monday and say they want Tanaka to remain with them for next season.

"We told him he is very important to us and we'd like him to stay," Tachibana said.

Under the rules of the three-year agreement announced Monday, a Japanese club may make players available between Nov. 1 and Feb. 1 and may set a price of up to $20 million.

Starting with the day after a player is posted and continuing for 30 days, any big league team willing to pay the fee may attempt to sign the player. A major league team pays the posting fee only if it signs the player, and the fee is then payable in installments, with the timing dependent on the amount.
