Lynn, who signed with Minnesota in the offseason, had drawn interest from NY in February.
Austin, who was ranked as New York's No.14 prospect in 2017 by MLB.com, will hope the change of scenery can turn his career around.
It's not an especially steep price to pay for Lynn, 31, but then Lynn has been a disaster for the Twins this year after he signed a one-year contract. He made 20 starts for the Twins, going 7-8 with a 5.10 ERA.
The Yankees are barreling their way toward a 100-win season, but in part because they trail the Red Sox in the AL East standings (and are thus in line to play in the wild-card "knockout" round), Brian Cashman has been busy reinforcing the pitching staff. He's likely to become a long reliever with the Yankees. Lynn can become a free agent after the World Series. Last season, Lynn started a league-high 33 games and posted a 3.43 ERA for the St. Louis Cardinals. Britton has appeared in two games for NY - to date - allowing a run in two innings of work.

In the capital, the first-placed CPP secured 456,899 votes, just over four and half times more than the number of spoiled ballots. Another polling station at a school was quiet, with a handful of voters casting their ballots in the mid-afternoon heat.
The Yankees also receive cash considerations in the deal.
The Houston Astros and Seattle Mariners reshaped their bullpens Monday while the Yankees added a starter before the trade deadline.
But Austin never became a regular with the Yankees, slowed by a broken left foot and right hamstring injury past year.
Austin, who made New York's Opening Day roster, appeared in 34 games earlier this season, hitting.223 with six doubles, eight home runs and 23 RBIs. Rijo. 19, had a 2.77 ERA and a 4-1 record in seven minor league appearances this season.
