Castro is currently third in the balloting among National League shortstops, released on Tuesday. He trails the Rockies' Troy Tulowitzki, who has 1,200,256 votes, and the Cardinals' Rafael Furcal, who has 1,183,096 votes. Castro has received 738,771 votes so far.
In the seventh inning on Sunday, the Twins had one out and a runner on second base when Drew Butera hit a ball to Castro at Target Field. Castro couldn't get his glove on the ball for an error, but instead of pouting, he ran after the ball and recovered in time to throw out the baserunner at home.
"It was a momentum switch, and then it switched right back in our favor in a couple seconds," Cubs manager Dale Sveum said. "It was heads up that you like to see from anybody. A lot of guys might have put their head down because they made the error. That was huge for him to jump on the ball and throw home."
Castro's goal is to win a Gold Glove. He also wants to be a regular on All-Star teams, and could represent the Cubs this year. So could first baseman Bryan LaHair, who is fifth among NL first basemen, trailing the Reds' Joey Votto, who leads the field with 2,108,725 votes. The Cardinals' Lance Berkman is second (851,373 votes) in the latest balloting, followed by the Braves' Freddie Freeman (828,759) and the Giants' Brandon Belt (563,708). LaHair has received 514,809 votes.
LaHair, 29, was batting .310 with 12 home runs and 25 RBIs in 52 games this season.
