Alcantara could grow into Cubs' leadoff role

Renteria says young switch-hitter needs to improve against right-handers

Alcantara could grow into Cubs' leadoff role

CHICAGO -- Arismendy Alcantara could be the Cubs' leadoff man of the future, manager Rick Renteria said Monday, adding that the switch-hitter needs to improve on his approach from the left side. Alcantara entered Monday's game batting .201 against right-handers, .247 against lefties.

"He's 22 years old," Renteria said. "We brought him up here and put him in center field where he had played 10 games previous in the Minor Leagues, and all things being equal, I think he's held his own."

As the leadoff man, Alcantara was 15-for-83 in 18 games this season.

Extra bases

• The Cubs expect to finalize their rotation for the last series on Tuesday. Kyle Hendricks was expected to start the season finale Sunday against the Brewers.

• The Cubs opened their three-week instructional league on Monday in Mesa, Ariz. The team is changing its format this year and will spend more time on drills and instruction than actually playing games, which won't begin until Oct. 6. Among the players participating are Kyle Schwarber, the team's No. 1 pick in the First-Year Player Draft, and Victor Caratini, acquired from the Braves for Emilio Bonifacio and James Russell.
