Sports are just built to be played in duos.
Joe Montana and Jerry Rice; John Stockton and Karl Malone; Johnny Bench and Pete Rose -- the list literally goes on forever of duos who pushed each other to the heights of their talent.
However, as Robin and Brook Lopez could attest, having a sibling-teammate can push a player higher, in different ways.
For Weber State softball's London and Cydnee Clarke, their sisterhood hasn't just made them better softball players. Instead, it's made them better people.
"It was a lot of fun," said London Clarke, when referring to the 2013 season's experiences of playing with her sister. "We didn't play against each other when we were younger, and I've gotten a lot closer to her. I love her."
London is a senior -- poised, quick, and hard-working; Cydnee is a sophomore -- competitive, hard-hitting, and youthful. Together, the two Weber High graduates have carried on a proud family tradition of competitive softball.
"Softball is big in our family," London Clarke said. "My dad played softball, and my aunt played college softball, so growing up, softball was big and we stuck with it."
With a natural ease on the field, London found herself climbing the competitive ranks -- a rise which inspired her younger sister, Cydnee, to try to do the exact same.
"London was a lot of my influence to play," Cydnee Clarke said. "I just looked up to my sister, because that's what a younger sister does. It was cool getting to play under her."
However, due to their age difference, the sisters weren't able to play on the same team, until both found themselves on the Wildcats' roster.
Weber State coach Tina Johnson said the Clarkes have made a tremendous impact on the still-young Wildcat program.
"The whole family is really big Weber State people," said Johnson, who is in her fourth season as the Wildcats' coach. "They really have bought into the program, and believe that Weber is a great place, and they want to leave a legacy."
Despite their similar resemblance and goals, the Clarke sisters are incredibly different people off the field, and Johnson noted their differences can be striking.
"They're so different, you forget they're sisters," Johnson said. "They look alike, but they're totally different athletes. London is very quiet and analytical; Cydnee is the opposite -- she's louder and much more free-spirited."
In 2013, Cydnee has been plagued by injuries, but London has been a regular presence in the Weber State lineup, starting 38 of 39 games for the Wildcats.
London's steady performance as a Wildcat, including two all-conference selections, has made her one of the bright stars in the Weber program's brief history, and Johnson stated London's senior day this Saturday against Southern Utah will be an emotional day.
"I've been telling myself to think other thoughts so I won't get so emotional," Johnson said, while fighting back tears. "It'll be really difficult, because she's been a huge part of what we're about."
Johnson's thoughts were echoed by Cydnee Clarke, who said it will be sad that she can no longer play with her sister.
"It will be very emotional," Cydnee Clarke said. "I'm definitely a crier, so there will be some tears shed."
Away from the ceremony, for London, who is still trying to figure out what to do with life after softball, the weekend will be just another test as the Wildcats attempt to get hot going into the Big Sky Conference tournament.
"It's kind of sad, but I've loved my experience here," London Clarke said. "It'll be a big matchup this weekend, so I'm excited for it."
