Masahiro Tanaka and Prospect Valuation
Masahiro Tanaka was finally posted last week. Now, for the next 25 days or so, he’s going to be the center of the baseball world, for all the reasons Tony talked about this morning, and the month long courting of Tanaka is going to end with him likely signing a deal that costs a similar amount to Shin-Soo Choo or Jacoby Ellsbury. Perhaps more, on an annual average basis, since his deal is likely to be for six seasons instead of seven, and teams will have to pay a $20 million posting fee in addition to the salary they negotiate with Tanaka. My guess is that he ends up at $120 million over six years, so the total cost will be 6/$140M with the posting fee, putting his final bill just slightly behind the 6/$147M that Zack Greinke went for last winter.
It is going to be, by far, the largest contract ever given to a player who has yet to play in the big leagues. Including the posting fee, Daisuke Matsuzaka cost the Red Sox about $100 million, while Yu Darvish cost the Rangers about $110 million. And those deals dwarf all of the contracts given to other international players: Jose Abreu got $68 million this winter after defecting from Cuba. Previously, Hyun-Jin Ryu went for $62 million including the posting fee paid to his Korean team, Yasiel Puig got $42 million (plus some potential arbitration payouts that could raise that number substantially), and Yoenis Cespedes got $36 million over four years. Even going back a few years, we see Aroldis Chapman at $30 million and Leonys Martin at $15 million.
