Red Sox DFA Eric Hosmer, get RHP Wyatt Mills from Royals - MLB

BOSTON – The Boston Red Sox designated veteran first baseman Eric Hosmer for assignment to make room for right-hander Wyatt Mills, who was acquired from Kansas City for minor league righty Jacob Wallace.

Hosmer, 33, batted .268 with eight home runs and 44 RBIs last season, when he was traded to the Red Sox from San Diego. In a 12-year career with the Royals, Padres and Red Sox, Hosmer has batted .277 with 196 homers and 879 RBIs.

Mills, 27, was 0-1 with a 4.60 ERA last season with Seattle and Kansas City.

Wallace, 24, had a 3.81 ERA in 47 appearances for Double-A Portland.

Also on Friday, the Red Sox traded utilityman Hoy Park to Atlanta for a player to be named or cash. Park, 26, hit .216 with two home runs for the Pirates last season. They traded him to Boston last month for minor league pitcher Inmer Lobo.

LOS ANGELES — Giancarlo Stanton, Josh Donaldson, and Tommy Kahnle were activated by the New York Yankees ahead of their weekend series against the Los Angeles Dodgers.

New York cleared three roster spots after a 1-0 loss at Seattle, optioning infielder-outfielders Oswaldo Cabrera and Franchy Cordero to Triple-A Scranton/Wilkes-Barre along with left-hander Matt Krook.

Stanton, Donaldson and Kahnle all played in a rehab game for Double-A Somerset. Stanton was hitless in three at-bats in his first appearance since injuring his left hamstring on April 15.

Donaldson went 1 for 4 in his fourth rehab game as he comes back from a strained right hamstring originally sustained on April 5.

Kahnle pitched one inning, giving up one run and one hit and walking two. He has been out since spring training with right biceps tendinitis.

Aaron Boone said he wasn’t concerned about Stanton returning after playing in just one rehab game. He did say that Stanton likely will be a designated hitter for a couple of weeks after rejoining the Yankees.

New York is missing centerfielder Harrison Bader, who strained his right hamstring against the Mariners and went on the injured list the next day.

Left-hander Carlos Rodón, sidelined since spring training by a sore left forearm and an ailing back, was transferred to the 60-day injured list.
