Wanna feel like a kid again? Underdog Kickball brings a fresh new twist to the adult recreational sports scene. Kickball... yes, just like you played in 5th grade, is a game that closes the age and gender gap, if but a little. This great playground pastime is now back for adults 21 and older to enjoy. So far, ages for players have ranged from 21-61, all in the same division. We at Underdog Kickball encourage rivalries, cheering, and general fun; but if you are an individual looking for an extremely competitive sport, our leagues may not be for you. Remember, it's just kickball, you can’t really get that worked up or mad about anything…it's just kickball. The idea behind kickball - past and present - is to have fun first, win second. Win or lose, what's better than being out there having fun with friends? And... the upside of kickball for grown-ups is the chance to go to a local sponsor bar after the game, socialize and hang out. Underdog Kickball is the largest group of kickball leagues west of the Great Plains. We are proud to offer quality adult coed kickball leagues in the greater Seattle area and surrounding suburbs. Underdog Kickball was originally founded in 2003 under the name Pacific Northwest Kickball, and is now happy to be part of the Underdog Sports Leagues network. Want to know more? Drop Us a Line!

What Division is right for me or my team? The Underdog has made a few rules adjustments aimed at keeping kickball goofy and fun no matter what level of competitive spirit your team wants to bring out on the diamond. For a more in depth explanation of rules variations between divisions, please click here. Rookie Division - New to Kickball for "Grown-Ups"? - Been a few years since you last got out on the playground? - Is your team more interested in coming up with themed outfits and nicknames than in winning the game? Rookie leagues are for teams who've never played Underdog Kickball, and would like a primer before they jump in with more experienced teams. Softcore Division - Has your team played kickball before? - But a few of your players still don't really know or care about the finer points of force outs or tagging up? - Would your team not really miss the scoreboard most games? Softcore is the place to be for teams that aren't Rookies but like that kind of feel. Crazy Kickball fun is the goal - with crazy outfits, a less than encyclopedic handle on the rules, and goofy chants all part of the plan. Midcore Division - Is your team kinda good at Kickball? - Like to treat Kickball a little more like a competitive sport? - Like to try out there on the diamond... but still have trouble remembering the score some innings? Midcore is the place to be for teams that have played multiple seasons of Underdog Kickball, and have a solid handle on both the rules of baseball/softball and the Underdog format. Fun is absolutely the goal - but it's alright to take a look at that scoreboard now and then, or to run that grounder out like you mean it (maybe while wearing a crazy 70s outfit, or a gorilla suit...). Hardcore Division As the vast majority of teams classify themselves as "Midcore," the Hardcore Division has been discontinued. Teams previously participating in Hardcore should sign-up for Midcore leagues. Rules have been unified across all Divisions.
