The Korea Professional Baseball League is currently a third of the way into the season, and on June 19th, rookie girl group members Son Na Eun and Yoon Bomi participated in the opening pitch for the LG Twins in their home game against the visiting SK Wyverns at the Jamsil Baseball Stadium. Having gotten a win yesterday after seeing Kim Tae Hee throw the opening pitch for them, the home fans and LG Twins players had the privilege of seeing girl group A Pink in action this afternoon. Yoon Bomi added beforehand, "We're already so happy at just being able to watch a game, so we're even more glad to be able to throw the first pitch and watch it with our fans." Main vocalist Jung Eun Ji sang the national anthem, while A Pink also performed during half-time. Meanwhile, the number '51' on the members' caps also caught attention as A Cube Entertainment revealed, "The number '51' belongs to LG Twins player, Bong Jung Keun and the girls wanted to show their support as he is currently out with an elbow injury. They also wished for his speedy recovery." Unfortunately though, the Twins lost 2:6 on the day. Check out the pictures and video from the event below! [gallery]
