MINNEAPOLIS — The disappointing Minnesota Twins have traded right-hander Lance Lynn to the New York Yankees for first baseman/outfielder Tyler Austin and right-handed pitching prospect Luis Rijo.

Minnesota will send $2 million to the Yankees as part of Monday’s deal to cover half of the $4 million remaining in Lynn’s $12 million salary.

The 31-year-old Lynn was 7-8 with a 5.10 ERA in 20 starts for the Twins, walking 62 and striking out 100 in 102 1/3 innings. He is likely to become a long reliever with the Yankees to replace Adam Warren, who was traded to Seattle on Monday.

Lynn also joins Luis Cessa as insurance for a starting rotation that includes Luis Severino, Masahiro Tanaka, CC Sabathia, Sonny Gray and newly acquired J.A. Happ.

Austin, 26, made his major league debut against Tampa Bay in August 2016, combining with Aaron Judge to become the first teammates to homer in their first major league at-bats in the same game.

But Austin never became a regular with the Yankees. He hit .223 with eight homers and 23 RBIs in 121 at-bats for New York this year and .247 with five homers and 11 RBIs in 97 at-bats with Triple-A Scranton/Wilkes-Barre

The 19-year-old Rijo is 4-1 with a 2.77 ERA in five starts and two relief appearances this year for Class A Tampa and Staten Island, and rookie level Pulaski.

Duke headed to Seattle

SEATTLE  — The Seattle Mariners worked on their bullpen again on Monday, acquiring left-hander Zach Duke from the Minnesota Twins and right-hander Adam Warren from the New York Yankees for a pair of minor leaguers.

The trades on the eve of the non-waiver deadline provided two more relief options for manager Scott Servais with Seattle in the playoff hunt in the AL West.

The Mariners sent pitcher Chase De Jong and infielder Ryan Costello to the Twins, and dealt international slot money to the Yankees for Warren.

“Obviously a lot of teams are looking to add to the bullpen this time of year with the trade deadline coming up. I’m not surprised,” Servais said. “It may not be the last thing we do.”

General manager Jerry Dipoto said recently he was hoping to add another righty to the bullpen and pick up a left-handed specialist as well to take some stress off James Pazos. He accomplished both by acquiring Sam Tuivailala from St. Louis late last week and then landing Duke and Warren.

“Zach adds both experience and left-handed depth to our bullpen,” Dipoto said. “We believe he can be an importance piece for us over the balance of the season.”

The 35-year-old Duke went 3-4 with a 3.62 ERA in 45 appearances for the Twins. He has limited left-handed batters to a .237 average this season.

Minnesota is sending $75,000 to Seattle as part of the deal. Duke is owed $716,667 of his $2.15 million salary. He has earned a $200,000 bonus for making 40 pitching appearances and can earn up to $1.3 million more, getting the entire amount if he makes 65 pitching appearances.

“Duke’s got a pretty good track record of getting lefties out. The last couple of years he’s been pretty good against the righties, too,” Servais said. “He’s got different arm angles, a little bit different look, he’s got experience, so a welcome addition.”

Duke was playing catch on the field before Minnesota’s home game against Cleveland when he was summoned for a meeting with chief baseball officer Derek Falvey, general manager Thad Levine and manager Paul Molitor.
