Robinson Cano and Kyle Seager generally patrol Safeco Field. On June 21, it will be Kaylee Andersen’s playpen.

Andersen, who just completed her eighth-grade year at Oak Harbor Middle School, will compete in the semifinal round of Major League Baseball Pitch, Hit and Run competition following the Mariners’ 1:10 p.m. game with the Houston Astros.

A win at Safeco would propel Andersen to the national competition, which will be part of the All Star Game activities in Cincinnati July 13 and 14.

Andersen won the local competition May 5 and then took the all-around title at the sectional June 7 in Snohomish.

Winning at Snohomish, however, didn’t guarantee Andersen a spot in the Safeco competition. The best scores from all of the sectionals from across the Northwest states were combined and the leaders were invited to Safeco.

Andersen said it is “amazing” to get to the semifinals.

“I’m a little bit nervous,” she said. “Competing in front of so many people can be nerve wracking.”

Andersen said she has been playing softball “since I was born,” but this is the first time she entered the Pitch, Hit and Run tournament.

In the competition, the athletes are asked to strike a target from 35 feet throwing over- or under-handed, hit for distance and accuracy off a tee and run for time from second base to home plate.

Andersen, the daughter of Erik and Michele Andersen, said last year’s winner at Safeco recorded 1,040 points. She scored 900 at Snohomish.

“I can improve on that,” she said, noting she connected on only three of six pitches at the sectional competition.

Andersen’s 10-year-old sister, Abigail, also won the Oak Harbor competition but did not advance from the sectional.
