Since 2010 the Denver Browns have competed in the City Championship every season with exception of 2014 and 2021 in which both years the Browns were bested by the (to be) City Champ in the semi's. The Denver Browns have competed in the National Adult Baseball Association (NABA) since 2007-2019 18WAAA & 2020-22 25WAA. No other ball club in the Denver metro area can boast such a feat and the Denver Browns have established themselves in elite company in the overall history of Denver Baseball. Manager Mike Onisko set to retire at the end of the 2022 season has been at the helm the past 9 seasons winning 5 City Championships and a runner up in the 2018 NABA National World Series. The Denver Browns stalwart skip was inducted into the NABA National Hall of Fame in 2021 due to his impeccable character and incredibly impressive record as a manager. Come out Sunday 9am at Denver Christian HS as the Denver Browns (#1) take on the Denver Bulls (#2) for the 25WAA City Championship Game and join us after for a very special Mike Onisko Appreciation Party right after going on all afternoon long at Buffalo Wild Wings - Free Beer from Tivoli Brewing - #supportlocalbaseball
