Clayton Kershaw pitched his first no-hitter Wednesday night, striking out a career-high 15 and allowing his only baserunner on a throwing error by shortstop Hanley Ramirez in the Los Angeles Dodgers' 8-0 victory over the Colorado Rockies. Kershaw's gem gave the Dodgers the only two no-hitters in the majors this season. Josh Beckett tossed one May 25 in Philadelphia. Kershaw (7-2) retired his first 18 batters before Corey Dickerson led off the seventh with a slow bouncer to Ramirez, whose throw on the run went wide past first baseman Adrian Gonzalez for a two-base error - ending any chance for a perfect game. That was the only runner allowed by Kershaw, a two-time NL Cy Young Award winner.
