之前小弟一直很好奇YAHOO預設的O-rank 不知道是依據何種ranking methodology來排的 (可能是按去年Rank 再加上FB那些專家的主觀微調吧) 而YAHOO的Ranking methodolody似乎也沒公佈搞得好像黑箱作業一樣所以不少新手會在中後段不知道要選誰的時候就會直接參考O-rank 當然老手往往就是可以從這些地方"偷"到被低估的選手剛好本身是學統計的運用簡單的工具自創了一個rank給版眾參考順便拋磚引玉看能不能激發更多數量化方式的評估選手方法 http://www.badongo.com/file/13465567 -- 先貼top 100 (U for under-rated, O for over-rated in O-Rank) Player Pos O-Rank R-Rank evaluation Álex Rodríguez (NYY - 3B) 2 1 Hanley Ramírez (Fla - SS) 1 2 David Wright (NYM - 3B) 5 3 Matt Holliday (Oak - OF) 36 4 U+ Albert Pujols (StL - 1B) 3 5 Lance Berkman (Hou - 1B) 18 6 Chase Utley (Phi - 2B) 22 7 U José Reyes (NYM - SS) 4 8 CC Sabathia (NYY - SP) 27 9 U Carlos Beltrán (NYM - OF) 19 10 Mariano Rivera (NYY - RP) 74 11 U+ Manny Ramírez (LAD - OF) NA 29 12 U Johan Santana (NYM - SP) 17 13 Ryan Howard (Phi - 1B) 10 14 J.Papelbon (Bos - RP) 50 15 U+ Ryan Dempster (ChC - SP) 149 16 U+ Russell Martin (LAD - C,3B) 41 17 U Grady Sizemore (Cle - OF) 6 18 Ryan Braun (Mil - OF) 8 19 Roy Halladay (Tor - SP) 58 20 U+ Miguel Cabrera (Det - 1B,3B) 7 21 O Chipper Jones (Atl - 3B) 65 22 U+ Tim Lincecum (SF - SP) 21 23 Jimmy Rollins (Phi - SS) 12 24 Magglio Ordóñe (Det - OF) 62 25 U+ Brandon Webb (Ari - SP) 46 26 U Joe Nathan (Min - RP) 72 27 U+ Josh Hamilton (Tex - OF) 9 28 O Mark Teixeira (NYY - 1B) 13 29 O Bobby Abreu (LAA - OF) 94 30 U+ Jake Peavy (SD - SP) 48 31 U Dustin Pedroia (Bos - 2B) 24 32 F.Rodrígu z (NYM - RP) 79 33 U+ Rich Harden (ChC - SP) 96 34 U+ Cole Hamels (Phi - SP) 45 35 Dan Haren (Ari - SP) 59 36 U José Valverde (Hou - RP) 126 37 U+ Nick Markakis (Bal - OF) 35 38 Brian Roberts (Bal - 2B) 38 39 Joakim Soria (KC - RP) 99 40 U+ Ian Kinsler (Tex - 2B) DL 11 41 O+ Carlos Lee (Hou - OF) 26 42 O Prince Fielder (Mil - 1B) 20 43 O Vlad.
