CHICAGO — Starlin Castro no longer appears to be the Cubs’ undisputed everyday shortstop.

The struggling three-time All-Star was out of the lineup Friday against the Giants because Manager Joe Maddon wanted to keep rookie slugger Kyle Schwarber, batting .345, in it.

“It’s because of Schwarber,” Maddon said. “Schwarber’s the guy who kind of enacted this whole thing by the way he’s hitting right now.”

The Cubs have a bit of a crowd at catcher with Miguel Montero coming off the disabled list before the game after being sidelined by a sprained left thumb and veteran David Ross in the mix.

Schwarber started in left field after catching Thursday. Chris Coghlan was at second with prized rookie Addison Russell moving to shortstop – his natural position.

“Addison is the shortstop today,” Maddon said. “He could be the shortstop tomorrow.”

GIANTS: Mike Leake, acquired in a trade with Cincinnati last week, was placed on the 15-day disabled list because of a strained left hamstring.
