Castro has come a long way in three years

Castro has come a long way in three years

CHICAGO -- Tuesday marked the third anniversary of Starlin Castro's callup to the big leagues. On May 7, 2010, the shortstop was promoted from Double-A Tennessee to the Cubs and hit a three-run home run in his first at-bat in Cincinnati.

Since that day, Castro, 23, leads all National League players with 477 games played and is tied for sixth among big league shortstops with 200 RBIs in that span. His 567 hits since his debut lead the NL and rank fifth-most in the Majors. Detroit's Miguel Cabrera leads all players with 587 hits in that span. Castro's 101 doubles since his debut rank seventh-most in the NL.

The shortstop entered Tuesday's game having hit safely in 25 of his 29 games. He also had a 14-game hitting streak from April 6-22, and batted .317 in that span.

Does Cubs manager Dale Sveum see progress with Castro?

"There's progress since the day he got here," Sveum said, "but I think it's still a work in progress with some mental things at shortstop. If he wants to get to another level swinging the bat, there's still a lot of improvement that can happen there to get the OPS higher. It comes and goes with him as much as anything. There's still quite a bit of improvement that can happen on both ends."

Part of the adjustments that need to be made involve Castro's timing at the plate.

"He has such unbelievable hand-eye coordination," Sveum said. "He fouls a lot of balls off and does a lot of things. He has to take advantage of hittable fastballs."
