The sound of home runs and fan cheers is back as Oklahoma’s pro baseball teams return to the diamonds this month. Oklahoma City’s RedHawks roost once more at RedHawks Field at Bricktown to the score of live music and foot traffic that has made it one of the city’s most popular summer attractions. The season for this Triple-A affiliate team to the Houston Astros begins with a home field advantage against Memphis on April 5. Nearer the Arkansas River, the Tulsa Drillers throw that first ball at its new home at downtown’s ONEOK Field on April 12 against San Antonio. Although the season begins April 5, the first home game for the Double-A affiliate to the Colorado Rockies is always special as new development continues to spring up in the Brady Arts District. Seasons continue through September. www.okcredhawks.com, www.tulsadrillers.com
