Grabski added that she wanted to break the 50-second barrier in both the 100 and 200.
"That 200 free time, I'm just so blown away with that time," she added.
Her teammate at the Sunbury YMCA, Lewisburg's Emily Maxwell, a senior, made the 100 final and tied for seventh with a time of 52.78 seconds.
"It was my last race and it was exciting as I know I have four years ahead of me, but I am going to miss my teammates," Maxwell said.
Maxwell's time in the final tied her best-ever for the event.
"I have nationals in a few weeks, so I know I am going to get better there."
In the 100 backstroke, Lewisburg sophomore Caitlin Foley finished fourth with a time of 57.94 seconds, just .05 seconds off of the third-place time.
"That's my best time," she said of the event. "My backstroke got so much faster this year and I moved up a place from last year (fifth) and I am just so happy."
Foley attributes her quicker times this year to lifting weights and giving up soccer to get an early start on training.
"It was hard to give up soccer as I played it for a very long time, but I am so glad that it paid off," she said.
