The Seattle Mariners have signed veteran slugger Justin Upton to a one-year deal after his recent release by Los Angeles Angels.
The four-time All-Star left the Angels in April, heading into a final season of a $106 million, five-year guaranteed contract so Seattle must pay him a share of the Major League Baseball minimum ($700,000).
Seattle are 100/1 to win the World Series and required help in the outfield following injuries to Mitch Haniger, who has a high ankle sprain and newcomer Jesse Winker, who is also struggling at the plate. Highly-touted youngster Jarred Kelenic being sent down to the minors also increased the need for Upton to stay.
Upton batted .211 with 17 home runs, 41 RBI's in 89 games last season with the Angels. He was the top pick in the 2005 draft and is a .262 career hitter with 324 home runs in 15 major league seasons with the Arizona Diamondbacks, Atlanta Braves, San Diego Padres, Detroit Tigers and the Angels.
To make room for Upton on the 40-man roster, right-hander Adrian Sampson was designated for assignment on Saturday following the 6-5 loss to the Boston Red Sox. The 30-year-old Sampson was claimed off waivers by Seattle from the Chicago Cubs and optioned to Triple-A Tacoma.
For the second time in three games, the Mariners' bats got hot before fading badly, allowing Boston to seize control to take advantage of pitching mistakes and handing Seattle a 6-5 loss at Fenway Park.
Seattle have been beaten three times at Fenway, where they will conclude their 10-game road trip looking to avoid the sweep on Sunday night, before heading home to face the Oakland Athletics on Monday.
