Summer sports preview

Yawn estimates this summer will be just as lucrative for the city, with estimated direct spending in the neighborhood of $5.7 million. Almost every weekend features some kind of event, and the fields at Old Settlers Park are scheduled to be full every weekend in June and July.

"The fields are closed in August, or I would have them full," Yawn said, adding that the fields are closed for maintenance during that time.

Most of the activity is either baseball or softball, a fact Yawn attributes to "first-class" facilities at Old Settlers Park.

However, the city has also attracted a number of unique sporting events.

Round Rock has, for example, hosted the Independent Women's Football League championship and all-star weekend for three straight years, with the fourth coming this year at the end of July.

The professional women's football league features teams from Montreal to California and Pennsylvania, and Yawn said the IWFL can draw spectators from all over the world.

The biggest draw, though, is still baseball. The Round Rock Convention and Visitors Bureau estimates that the Super Series World Series—a tournament put on by Round Rock's own Blue Diamond Tournaments—will create nearly $2.35 million in direct spending over the course of the two week-long tournaments (one for even ages and one for odd ages).
