Castro relieved he will not face criminal charges

CHICAGO -- A relieved Starlin Castro arrived at Wrigley Field on Saturday, a day after Cook County prosecutors said they will not file charges against the young shortstop for criminal sexual assault.

Allegations against Castro were investigated by Chicago police and the state's attorney's office. On Friday, state's attorney spokeswoman Sally Daly said that insufficient evidence was found to charge the 22-year-old, which was welcome news to the Cubs' franchise shortstop.

"I'm happy that we got it resolved," Castro said. "I'm staying focused on the field and the game. I'm happy that the thing is over."

Though Castro cooperated with authorities when the investigation began in January, his attorneys claimed the charges were baseless.

"We're pleased for Starlin that this issue is resolved and glad that he can continue to keep his focus on baseball activities," general manager Jed Hoyer said in a statement.

If the charges were weighing on Castro's mind, you couldn't tell from his performance at the plate. Castro entered Saturday's game hitting .352 and was tied for third in the National League in hits and stolen bases. Last season, Castro became the youngest player to lead the NL in hits with 207.

"I came out to play every day and not think about that in my mind," Castro said. "It's kind of a tough thing to think about, but I stayed dialed in my mind and concentrated and played baseball."

Still, Castro said he has taken valuable lessons from the experience.

"I learned a lot," said Castro, who hit an RBI triple in the second inning. "I learned a lot of stuff, to be careful."
