Ken Rosenthal of FOXSports.com cites one league executive who believes Royals OF Jose Guillen may not be a bad deal for the stretch run because he's motivated by his next contract.
"He is motivated when it’s time to earn money for the next year," one rival executive says. "He’s always been that way, a one-year contract guy. Somebody may get him and get themselves a really motivated player."
This is hardly restricted to Guillen. I would say the majority of players are like this. It's not unusual for guys to put up career numbers in a contract year.
