Popular girl group members are often invited to throw the ceremonial opening pitch at professional baseball games, a sport loved by many Koreans. In the past year, members from Girls' Generation, Wonder Girls, f(x), and miss A were asked to throw the first pitch at games in Seoul and also overseas.

The invitation to throw the opening pitch more than often coincides with the promotion of a new song or comeback by the girl group, and signifies that the idol has achieved an admirable level of popularity.

The pitching girl group member is usually led to the center of the baseball field by a giant, energetic mascot, while she smiles and waves cheerfully at the audience. She is also expected to bow to the audience who are sitting at different sides and then to throw a ceremonial pitch to the catcher that will be caught on camera for millions to see.

One of the most impressive opening pitches made by girl group members in Seoul was the throw made by miss A's Fei on April 30 at Seoul Jamsil Baseball Stadium this year. At the game between Doosan Bears and KIA Tigers, Fei showed off a great stance and beautiful pitching form as she threw the ball straight towards the catcher.

At this, even the announcer for the broadcast praised her successful throw by saying that idols nowadays are becoming more athletic than ever. At the time she pitched for the Doosan Bears, she had started individual activities apart from miss A. Now, she has not only proven her athletic abilities but also showcased her dancing skills on "Dancing With the Stars 3" and her cooking skills in "Master Chef Korea Celebrity."

Also throwing for the Doosan Bears, f(x)'s Krystal made an impressive pitch as well when she attended the game between Doosan Bears and Nexen Heroes on June 19 of last year. Known as an "athletic idol," she demonstrated her flexibility and athletic ability by making a swift throw, causing numerous Korean news reports at the time to report on how impressive her throw was.

After she showcased her athletic skills in the ice-skating reality competition "Kiss & Cry" by SBS, she was invited to make the pitch during her promotional period with f(x) for their comeback song "Electric Shock." Upon seeing her amazing pitch, netizens praised her stance and pitching and compared Krystal to her older sister, Girls' Generation's Jessica.

Yubin, rapper of Wonder Girls, was also invited to make the first pitch for the Doosan Bears at the May 27 game against Lotte Giants last year. Her confidence in throwing the ball with full force was praised, and the catcher successfully caught her perfect throw.

Although Fei, Krystal, and Yubin were able to showcase their athletic ability through the ceremonial pitches, other girl group members were thoroughly embarrassed as they made less-than-perfect throws.

One of the more embarrassing throws was made by Girls' Generation's Tiffany just a few weeks ago at the game between Los Angeles Dodgers and Arizona Diamondbacks on May 6. It was a special moment for Tiffany since she grew up in Diamond Bar, California. Joining top celebrities like Victoria Beckham, Sharon Stone, Harrison Ford, and Matthew McConaughey who also threw opening pitches at the stadium, Tiffany was the first k-pop idol star to throw a pitch at the Los Angeles stadium.

Hyun-Jin Ryu, who was a Korean pitcher for the team, was the catcher for Tiffany's opening pitch. Unfortunately, Tiffany's pitch was less than ideal. The ball went out of the strike zone, but netizens comforted her by saying that it was "still adorable." Tiffany's embarrassing throw was reported on Fox Sports Arizona, which called Tiffany's pitch "maybe the worst first pitch you've ever seen."

However, despite not having made a great throw, Tiffany was still not the worst, according to netizens. The most infamous and epic worst first pitch was none other than the one made by fellow Girls' Generation member, Jessica in May of last year. Pitching for the LG Twins, Jessica tried hard to throw the ball successfully, but the ball ended up planting straight into the ground and never made it to the catcher. Jessica and audience alike were quite pleasantly surprised, as she let out an embarrassed laugh afterwards.

While throwing an opening pitch can be a great opportunity for popular girl group members to showcase their talent in athletics, it may not be so much of a good idea for idols who are not quite as athletic. Well, the good news is, the adorable throws by Tiffany and Jessica will most likely live forever in internet infamy!
