The Yankees have been hit with a $13.9M luxury tax bill, their lowest since 2003. The fee, assessed Thursday by MLB under its labor contract, is down from $18M last year and $25.7M in 2009, when the Yankees won the World Series. Boston, which missed the playoffs this year, is the only other team that will have to pay a tax. The Red Sox received a bill for $3.4M, up from last year's $1.5M.
