Philadelphia Phillies pitcher Cliff Lee was scratched from his scheduled start Saturday because of a stiff neck, and that news adds to speculation about Lee's possible trade status.
Phillies general manager Ruben Amaro Jr. said Friday he is open to trade offers for several Phillies players, including Lee, according to ESPN.com.
Left-hander Raul Valdes will take the mound in Lee's absence Saturday, while outsiders wonder whether Lee's absence is part of an effort by the Phillies to complete a trade for him.
There is no indication that Lee's absence is the result of anything other than the stated injury.
"It's pretty serious as far as him moving it," Phillies manager Charlie Manuel said of Lee's stiff neck.
Lee, 34, is 10-4 with a 3.05 ERA this season. He is owed $50 million in 2014-2015 and has a $27.5 million vesting option for 2016.
The Red Sox, Cardinals, Dodgers, Pirates, Indians and Braves are seeking a starter.
