Some good news, bad news for the Kardashian family -- they got Alex Rodriguez to coach their family softball game ... problem is, A-Rod tells us he SUCKS at softball!
J Lo's boyfriend showed up at the field Thursday and suited up for Team Kardashian -- aptly named the Calabasas Peaches -- featuring Kim, Kourtney, Khloe, Kris, Kendall and some other friends.
They were up against a team in red while cameras rolled for their show.
