Clayton Kershaw crossed another first off his career list Monday, though it's unlikely he'll remember this one fondly.

The Los Angeles Dodgers left-hander surrendered a grand slam to Philadelphia Phillies outfielder Aaron Altherr in the sixth inning. It was the first grand slam the 29-year-old has allowed in his 10-year career, coming in his 288th regular-season start.

Kershaw entered the game holding opposing hitters to a .193/.233/.250 slash line with the bases loaded in 103 career opportunities.
