The Orioles have finalized a six-year, $66 million contract extension with outfielder Nick Markakis, according to baseball sources. Markakis will be in Baltimore later this week to take a routine physical and to sign the contract. The deal, which will keep one of the organization's building blocks with the Orioles through at least the 2014 season, could also include some incentives and a limited no-trade clause. In terms of guaranteed money, it will be the second-most expensive contract in Orioles history behind only the six-year, $72 million pact given to shortstop Miguel Tejada in December 2003.
