LEWISBURG - It's pretty easy to tell when an athlete has passion for their sport. One of the main attributes of a passionate athlete is they're never satisfied.

That's the kind of athlete that describes Northwestern junior Trey Shackleton.Shackleton turned in a very solid performance on Friday, swimming a time of 1:42.68 in the 200 freestyle to come home with a sixth place medal at the PIAA Class AA state championships. Shackleton improved on his performance from 2013, where he finished seventh, but after he got out of the water and walked from the ramp to the side of the pool it was easy to see he was not thrilled."To be honest I wasn't really happy with my race. I know I'm capable of way more than that," said Shackleton. "I just let the race get away from me a little a bit, and I felt like I was slipping through the water. Coming off my turn is one of my strongest areas and I wasn't really able to work that as much as I would like tonight. I know I have the potential to go faster. Today just wasn't my day, so I'm just going to try to come back faster (Saturday) in the 500 freestyle."Not many athletes would be as hard on themselves as Shackleton was, but as he noted it's is great motivation for the second day of competition where he will compete in the 500 freestyle. Shackleton knows the field will be tough once again, but he believes he will swim much stronger than he did on Friday."I feel like I have the returning speed to have an excellent 500 (Saturday)," said Shackleton. "In the 500 I'll be a little more relaxed and I'll be well rested. I know I have the potential to go faster."Shackleton's swim coach Ryan Woodruff also believes his student will be better. He also noted the kind-of swimmer Shackleton is and the work he puts into trying to do his best."Trey isn't super satisfied with his swim tonight and we both think he's capable of going a second or two faster. Trey is the kind of guy who will bounce back, though, and he'll come back stronger for the 500," said Woodruff. "He's really one of the most dedicated kids we have and he's built more for the 500, so we expect big things on Saturday."Butkus finishes 12thTamaqua had two representatives Joann Butkus and Rebecca Kanaskie in the championships Friday. Kanaskie wasn't able to move on in her event, but Butkus qualified for the B final in the 50 freestyle with a time of 24.77, which put her 14th overall.Butkus' original seed coming into the meet was 12th, and she made it evident she wanted to get back to that placement when she competed in the B final Friday night. That's exactly what Butkus, a senior, was able to do as she finished with a time of 24.66 (her second-best time ever) to finish 12th overall."I wanted to come back with a vengeance tonight and I did," said Butkus. "I'm very happy with the way I performed tonight. I wanted to improve on my time from my first swim of the day and then get back to where I was seeded, which was 12th. I did all that, so I'm happy and I couldn't think of a better way to wrap-up my senior season. Now, I'm going to focus on tomorrow where I can hopefully end my career on an even better note."Butkus will be continuing her swimming career at Division III Susquehanna University where she will major in Bio-Chemistry with a direction in pre-med.Kanaskie, a freshman, placed 25th in the 200 individual medley. The Raider turned in a time of 2:17.74.
