Why wasn't Sophie Gustafson wearing a Seattle Mariners hat last week in Portland, Oregon?

Question

One of her sponsors is Major League Baseball, and usually she wears the logo (hat and shirt) of whatever team is closest to the site of the tournament she's playing in. But last weekend, she wore New York Yankees and Cleveland Indians logos during the three rounds of the tournament. According to lpga.com, MLB tells her which logo they want her to wear, which would be the Mariners. She has worn the Mariners logo in the past.

Answer 1

The reason may be that Seattle is not in the state of Oregon ? So if no team exists in the state or metropolitan area where an LPGA event is held who determines the cap she will wear ?
