With the smell of grass and leather in the air, the reigning Ivy League baseball champions, the Columbia Lions, under Coach Brett Boretti, are sharpening their claws and licking their chops — again. Winners of four Ivy League crowns in the past six years, the Lions defend their latest title in the Ivy League opener against Cornell on March 23. You can track the Lions on WKCR-FM 89.9 or WKCR.org.
