Josh Hamilton is seeking a second opinion from Dr. James Andrews on his left knee.

Hamilton, who has had two surgeries since September, had a cortisone injection in the knee last month after several weeks of renewed soreness.

The injection provided relief for about three weeks.

"He's had his ups and downs this offseason, and we'd like to find out if there is something else we can do," Jon Daniels said. "You would like to have a better handle on what we can expect from him this year."
