Los Angeles Dodgers manager Dave Roberts isn't quite ready to anoint Walker Buehler his official ace just yet. Roberts on Monday announced the starting rotation for the Dodgers' season-opening series against the San Francisco Giants March 26-28, and longtime ace Clayton Kershaw is getting the ball on Opening Day. Kershaw's recent battles with injuries, his declining numbers (though still superb by most pitchers' standards), and the emergence of Buehler had many wondering if this would be the year Roberts gave the ball to his 25-year-old right-hander rather than his veteran lefty, who turns 32 later this month, against his team's longtime rival at Dodger Stadium.
