How are free agent deals determined?
自由球员合约是怎么签订的?
By Vince Gennaro, Special to Yahoo! Sports
Center fielder Torii Hunter will be paid $90 million over five years by the
Los Angeles Angels. Another center fielder, Andruw Jones, will get $36.2
million over two years from the Los Angeles Dodgers.
Closer Francisco Cordero signed a four-year, $46 million deal with the
Cincinnati Reds. Another closer, Eric Gagne, got a one-year, $10 million
contract from the Milwaukee Brewers.
Starter Carlos Silva will be paid $48 million over four years by the Seattle
Mariners. Silva, however, is the only starter from the free-agent class of
2008 to get more than a one-year commitment.
洛杉矶天使队将会付给中外野手Torii Hunter五年九千万美金的支票，而另一个中外野
手Andruw Jones则是跟道奇队签下了两年三千六百二十万美金的合约。
辛辛那提红人队跟终结者Francisco Cordero签下一份四年总额四千六百万美金的合约，
至于另一个终结者Eric Gagne则从密尔瓦基酿酒人队手中拿到了一份一年一千万美金的
合约。
西雅图水手队以四年四千八百万美金的价格签下了先发投手Carlos Silva，而他也是08
年自由球员当中唯一获得复数年合约的先发投手。
What factors caused the disparity in those contracts, and others? To provide
answers, I employed statistical tools – primarily regression analysis – to
examine last winter’s free-agent market.
I tested various measures of past performance, whether players at certain
positions were paid a premium or a discount, and examined the impact of age
and injury history. I also tested for evidence of a player’s marquee value –
were the most popular stars paid a premium, after adjusting for all other
factors? Also, did the timing of the signing impact salary? Did players who
inked deals in November and December fare better than late signees?
是哪些要素影响到了这些合约和其他合约之间的差异?为了找出答案，我应用统计学的工
