"I'm concentrating on become the best football player I can right now," Locker told ProFootballTalk.com. "That's where my focus is and that's where my efforts are going to be and that's where they'll continue to be."
The Angels drafted the quarterback in the 10th round of the 2009 draft, gave him a $250,000 signing bonus and hold his rights until August of 2015.
Angels general manager Tony Reagins said last week he was hoping Locker would weigh his options.
"I think there are some factors out there that are going to make his decisions more difficult," Reagins said. "The labor situation is one, where he's selected is one of them. Our eyes are wide open in this regard and we'll see how it plays out. You always have a chance."
After his junior season, Locker was viewed as perhaps the No. 1 overall pick in the NFL draft. After an inconsistent senior season, he has fallen to No. 4 among quarterbacks in the eyes of ESPN.com's Mel Kiper Jr.
Locker was a standout pitcher and outfielder at Ferndale High School in Washington. He played in a college baseball summer league in 2008.
