Castillo makes 'rookie mistake' after big day

CHICAGO -- Chicago Cubs catcher Dioner Navarro may have put it best after his buddy Welington Castillo skipped out on talking to the media after Castillo's first four-hit game in a 6-2 win over the Texas Rangers on Thursday.

"Rookie mistake," Navarro said with a laugh.

Castillo presumably got out of the locker room quickly to head to Milwaukee where the Cubs open a series on Friday. When they do, there's a good chance he'll be the leading hitter in all of baseball with a .425 average. His .452 on-base percentage ranks sixth.

"If he could swing the bat like this all year long we could have something special because (his) defense behind the plate is one of the best in baseball," manager Dale Sveum said after the game.

And coming from Sveum that's meaningful. It wasn't long ago the Cubs skipper was still curious what kind of player Castillo was going to be -- he said as much at the end of spring training when Castillo hit just .204 while striking out 13 times in 49 at-bats. He looked anything but ready for the season.

Once the switch was flipped for real, though, Castillo took off. His four hits on Thursday went to all parts of the ballpark. More than anything it means for this season, Castillo is showing he might belong in the core for the future. You know, when the Cubs are ready to contend.

They have a check-mark at first base (Anthony Rizzo) and shortstop (Starlin Castro) and probably one in Jeff Samardzija at the top of the rotation. Getting one behind the plate might make this year a successful one on its own.

Then maybe his "rookie mistakes" will be behind him.
