Seattle Mariners spokesman Tim Hevly said by email late Monday afternoon that he has been in contact with the Mariners' star, adding, "he and his family are safe."
Several neighbors called 911 after seeing smoke coming from the home.
The Bellevue Fire Department tweeted that the majority of the fire at the home in the 9500 block of NE 1st Street was quickly knocked down. There was no immediate information on the extent or cause of the fire.
Firefighters from nearby Redmond and Mercer Island joined Bellevue crews to attack the blaze, which started around 4 p.m.
The fire caused damage in the home's first floor, and the second floor suffered smoke and water damage, according to fire department officials.
"It's always devastating when folks come home to something like this, so we're trying to work with the family members and protect as much as we can inside," said Lt. Richard Burke with the Bellevue Fire Department.
Neighbor Maja Arnold saw the fire trucks and wanted to make sure everyone was safe.
"Everybody's okay," she said. "Luckily and that's the most important thing"
King County public records show the 5,100-square-foot house listed as belonging to Felix A. and Sandra Hernandez was built in 2009 and is valued at $2.85 million.
Real estate website Curbed featured the home in a February 2013 article soon after Hernandez signed a 7-year, $175 million contract extension with the Mariners.
