TAMPA, Fla. — Blake Treinen will begin the season as Washington’s closer, even though he has only one big league save.

After the Nationals lost Mark Melancon to the San Francisco Giants in free agency, Treinen won the job over Shawn Kelley and Koda Glover.

“Blake has that turbo sinker,” manager Dusty Baker said Thursday. “He may give up a hit or a walk, but he’s always one pitch away from getting two outs with one pitch.”

Detroit released right-hander Mike Pelfrey, who is guaranteed $8 million in the second season of a $16 million, two-year deal.

Pelfrey went 4-10 with a 5.07 ERA last season with the Tigers. He was 2-3 with a 7.94 ERA in three spring training starts.

Aaron Judge won the Yankees’ right field job, a decision that left Aaron Hicks as New York’s fourth outfielder, and Luis Severino has earned the fourth spot in the starting rotation.

Judge, 6-foot-7 and 282 pounds, has a .344 spring training average.

Milwaukee said it will place starter Matt Garza on the 10-day disabled list to the start the season because of a strained right groin.

San Francisco Giants general manager Bobby Evans informed 38-year-old infielder Jimmy Rollins he won’t make the team out of spring training and is waiting to hear back from him or his representatives about what options might be next.
