Chicago Cubs shortstop Starlin Castro looks at Darwin Barney’s Gold Glove award with the slightest bit of envy. As much as he’s accomplished in his first three seasons with the Cubs- two All-Star appearances and 529 hits- there are still areas where Castro needs to improve, including his defensive play. “I want to be like Barney and win a Gold Glove,” he said Tuesday at Fitch Park. “It’s going to be fun winning Gold Gloves at shortstop, second base and first base, because (Anthony) Rizzo is pretty good, too.

I know like I can be like those guys and play very good defense.” Castro is still considered the shortstop of the future, though Javier Baez may take his spot down the road. Castro isn’t worried about the competition, knowing that if he plays the way he’s capable of, everything will work out fine. “It’s one thing I challenged him to do,” manager Dale Sveum said. “’Your next step now is to win a Gold Glove.’ Obviously that takes a lot of focus and hard work, and being focused for 150 pitches a game over 162 games. He’s got the ability to do it. The rest is up to him.” Castro will never be able to live down the Bobby Valentine incident in 2011, when the former ESPN announcer called him out for having his back turned to the plate during a pitch. And he still hears about the game in San Francisco last year when he forgot how many outs there were and began running off the field. “Besides obviously a couple lapses, and that (Giants game) was obviously a very noticeable one… he improved tremendously throughout the season,” Sveum said. “Hopefully he keeps improving. That’s all we’re asking for from him.” If the Cubs win, Castro believes he will thrive. He’s one of the game’s brightest stars, but isn’t yet on the level of Troy Tulowitzki. “I’ll be (a bigger) superstar than I am,” he said. “I know that I can be what I’m supposed to be in the future. I know I can be very good because I’ve never been lazy. I work hard and be better every day.”
