龍子と成子は2人とも日本ジュニアテニスツアー2012年年間ランキング女子の部第1位!の成績で2012年を終えました。年明けすぐのランキングでは14才以下の部と12才以下の部の新年齢枠でそれぞれ全国第1位を取り、新年をスタートさせました。

成子は、12才以下だけでなく、14才以下の部の試合でも果敢に攻めて、10才以下の部トップの地位には5月に、全国全年齢1位(18才以下)の座へは10月に到達しました。とはいえ、18才以下の部で10才の選手がそのように昇進した事実がJOPのポイントシステムを刺激したのでしょう、2013年からシステムが変更されてしまいました。

龍子は2012年の最後2週間のみですが12才以下の部1位の座に着きました。6月の背骨骨折以降痛みに苦しんだことを考えると、この結果は怪我以前の正味6ヶ月間で得たものになります。今年のカムバックストーリーに第6回トーマスカップにて選ばれました。

While the bone had healed from her broken back, the nerve damage in her neck/left shoulder continued to linger throughout the year for Angelyna Tatsuko. The pain was bearable as she continued to play tennis, but long matches or multiple rounds a day would result in numbness or loss of strength in her left arm causing inconsistent service tosses or periods where she was unable to use her two-handed backhand. The impact from running also forced her to rely on cycling only for conditioning, which naturally hindered her speed and stamina. The handicap widened the gap between her and the top juniors, and took an enormous toll on her mentally and emotionally in 2013.
Christyna Seiko is misdiagnosed with growing pains in her knees and thighs for over four months before a chiropractor finds that she has a dislocated hip that created an inch difference in the length of her left leg. She has instant relief when it was popped back in place, but she suffers cascading injuries from her hips to her ankles throughout the year. She last runs in February, joining her older sister in limited cycling for conditioning the rest of the year.

Abuse from outside tennis coaches/officials result in serious injury in August that limit her time on court for months, while attempts to compensate for the pain in her legs continue the vicious cycle of again straining her hip. Her physical trials culminate in a complete, grade 3 ruptured hip flexor that ends her tennis campaign in November and puts Christyna Seiko out for three months!

Cross-training has always been an integral part of the ACE Tennis Elite Training System. Swimming has always been the primary cross-training activity, while throwing and catching a baseball has been a key part of their physical training for three years.
2013 saw three new cross-training activities added: Horseback riding, chess and throwing and catching an American football because of their love for the hit U.S. TV series, Friday Night Lights. Below are all the activities that the girls have done seriously as well as their developmental purposes:

• Swimming (breathing/overall strength)
• Aikido (discipline/fear-to-aggression)
• Stage Acting (confidence/public speaking)
• Basketball (footwork/coordination/vision)
• Hip hop dance (rhythm/flexibility)
• Boxing (footwork/mental/fear-to-aggression)
• Badminton (hand-eye/footwork)
• Modeling (confidence/image awareness)
• Baseball (hand-eye/shoulder)
• Horseback riding (mental composure)
• Chess (tactical thinking)
• Football (hand-eye/shoulder)
