One lifeguard has seen it all at the pool, from swimmers starting to go under, to fly balls, to guests who aren't clear about the dress code.
Some say it's the best seat in the house, the pool suite overlooking center-field. The suite draws corporate parties and those who just like to party.
"They're pretty rowdy, you know it's a lot of fun because you know it's high energy, and it keeps us on our toes, to make sure everyone is safe and doing the right thing," said Lifeguard Samantha Jernigan.
Samantha Jernigan is one of the five lifeguards that work the Diamondbacks pool. She's a true multitasker; watching out for swimmer safety and for all the fly balls.
Fifty home run balls have made their way into the swimming pool, but thankfully no one has been hit by one, but she did see a guy almost break his leg when he tried to jump over the wall.
It's not just the trespassers who are confused about proper pool protocol.
"They'll wear swimsuits that are like the g-string, and it's like alright everyone can see you, it's a fishbowl down here," she said.
Perhaps the most famous scene at the pool, the L.A. Dodgers taking the plunge.
"They came in cleats full of dirt, dirty jerseys, and the pool was a mess," said Jernigan.
Thankfully Samantha has only had to rescue one fan from the pool, her #1 focus is always safety, watching the game is a secondary perk.
"I feel so lucky to say that I am one of the only lifeguards in the world that get to work at a Major League Baseball Stadium, that is probably the best thing," she said.
Samantha says one of her favorite groups to watch is a repeat group of Pirate's fans who rent out the pool every year. The lifeguards are of course Diamondback fans, so it's a fun day full of rivalry that they look forward to each season.
