She recently retired from professional softball to focus on family – and Jennie Finch has decided to expand hers.

The Olympian and husband Casey Daigle are expecting their second child in late June, the softball star tells PEOPLE exclusively. The new baby will join big brother Ace Shane, 4½.

“Casey and I are beyond excited to be expecting our second child,” Finch, 30, says. “We love being parents to Ace and feel extremely blessed to grow our family. Ace can’t wait to be a big brother!”

After winning gold in Athens and silver in Beijing, Finch is now “a mommy, first and foremost!” She also works with kids at the Jennie Finch Softball Academy and Jennie Finch Softball Camps, and is co-chair of ‘nPLAY, a coalition of pro athletes dedicated to fighting childhood obesity.

Finch and Daigle, a Major League Baseball pitcher who has played for the Diamondbacks, Twins, Rangers and Astros, wed in 2005.
