MIAMI -- A person familiar with the negotiations tells The Associated Press that the Miami Marlins have traded right-handed reliever David Phelps to the Seattle Mariners for four prospects, including highly regarded outfielder Brayan Hernandez.
The person confirmed the deal to the AP on condition of anonymity Thursday because the teams have not announced the trade.
Phelps is 2-4 with a 3.45 ERA in 44 games and 47 innings this season. He's a six-year veteran with 64 career starts.

Hernandez, a 19-year-old Venezuelan, is batting .259 in 31 games in the minors this year.
The Mariners entered Thursday three games back in the AL wild-card race. The Marlins are out of playoff contention and looking to upgrade a farm system widely ranked among the worst in the majors (see full story).
Sandoval to reportedly return to Giants on minor-league deal.
SAN FRANCISCO -- A person with knowledge of his plans tells The Associated Press that Pablo Sandoval plans to sign a minor league contract to return to the San Francisco Giants.
The person spoke to the AP on condition of anonymity Thursday because the agreement had not been announced.
Sandoval technically will not be free to agree to a deal with a team until 1 p.m. Eastern Friday.
The Boston Red Sox released Sandoval on Wednesday when the third baseman didn't report after being designated for assignment last week.
It officially ended the Boston tenure for the slugger, who never was healthy enough to live up to the expectations that came with the $95 million free agent contract he signed in 2014.
With the Red Sox unable to find a team willing to take on part of his salary, the 2012 World Series MVP with the San Francisco Giants moved on after a total of 161 games, 575 at-bats, 136 hits and 14 homers for Boston -- but not a single one of them in the postseason.
