Shawn Johnson has been in the public eye for quite a few years now. In fact, there's been a whole other Summer Olympics since first arriving in the spotlight in Beijing in 2008. Unfortunately, due to injuriesshe wasn't able to compete in London last summer but she followed up winning a gold and three silver medals in Beijing with a Season 8 victory on Dancing with the Stars. Recently, she finished second in the All-Stars edition of the show.
In addition to throwing out the first pitch, Johnson was the guest conductor for the 7th inning stretch too.
Also notable that day? Cubs defeat the Astros in the 13th inning with a walk-off grand slam by Alfonso Soriano to maintain a half game division lead over the Cardinals.
