Long, Hernandez would go to Padres
General manager Kevin Towers said the A's requested pictures of the MRI exam Kotsay had on a herniated disk in his lower back. Those were sent Wednesday by overnight courier.
"They looked at the written part and it seemed fine with them," Towers said. "If they're comfortable with what we're sending them, we should be able to announce the deal."
Kotsay is expected to be Oakland's leadoff hitter and everyday center fielder.
"Mark is anxious and hopeful that a trade will be finalized but he understands that the Oakland medical staff has to sign off on it," his agent, Jeff Moorad, told the San Francisco Chronicle.
Oakland will be in the market for a catcher, most likely via a trade, and a starting pitcher at the back end of the rotation following Tuesday's trade of left-hander Ted Lilly to Toronto for outfielder Bobby Kielty.
According to The Chronicle, Kotsay will get an automatic $1 million extra per year because he was traded; the A's are scheduled to pay him $6.5 million a season for the next three seasons. An additional clause in his contract stipulates that because Kotsay was traded, each remaining year becomes a player option -- so Kotsay could declare free agency after any of them.
"The last thing that Mark or any people in his camp are thinking about is his ability to be a free agent after each year," Moorad told The Chronicle. "He's very excited with the idea of playing in Oakland for the balance of his contract."
