PHOENIX -- Eight-year-old Hailey Dawson threw out the ceremonial first pitch at the D-backs game Saturday, delivering another inspirational strike along her journey to complete a tour of all 30 Major League stadiums this summer.
Dawson celebrated by wagging her specially crafted plastic right hand and doing a few impromptu dance moves as designated catcher David Peralta raised his hands skyward.
"She's a ball of energy," her mother Yung said.
Hailey was born with Poland Syndrome, a condition that caused her to have a missing right pectoral muscle.
