In the sport of tennis, it is always good to have a playing partner available at any time to hone your skills, work on various aspects of your game or just play a match for fun if the spirit moves you.Tine and Miha Valencic know this very well, as the fraternal twins, originally from Slovenia, have become two important cogs in the powerful machine of Grapevine High School tennis.Coach Angel Martinez said he has been impressed with the brothers’ play from the outset and said, as sophomores, it is a good feeling knowing that they will be around for the next couple of years.“They both bring an amazing amount of talent,” Martinez said. “They are both very passionate. They are two of the hardest working kids on our team. They are both students of the game, and they are both very cognitive players. They always know what's going on in a game.“Sometimes they can show me things that are going on in a game, and I will just say, 'Oh, wow, you're right!'”Tine, who is a No. 4 singles and No. 2 doubles player, said concentration on his own performance is key to his game.“I try to stay focused on matches and win those two matches for the team,” Tine said. “I try to concentrate on my own play and not let my opponent dictate the match to me, and that has worked out very well for me.”Tine said he has been impressed with the Grapevine tennis team so far this season.“We have a pretty young team this year, but we have done really well,” Tine said. “We have done a lot better than last season, and I am really excited for how we can do next year.”Tine, who is ranked third in his class at the moment, said while he and his brother have experienced sibling rivalry in the past, that is really no longer the case.“It used to be competitive,” Tine said. “Then he started beating me every time, so it ceased to be competitive.”For Miha, the No. 1 boys singles player at Grapevine, the objective is to provide leadership to his younger teammates.“I just try to set an example for everyone else to follow,” Miha said. “I want to go out there and play and be a good example.”Miha said that he and his brother are both very supportive of each other and “want the best for each other.”“We usually play each other once or twice a week, so we spend quite a bit of time together,” Miha said.Miha and Tine said their goals for the spring season are to qualify for the regional meet, with Miha saying he hopes that state could be a possibility.Miha is ranked first in his class at Grapevine High School.
