Mariners acquired RHP Nate Karns, LHP C.J. Riefenhauser and OF Boog Powell from the Rays for SS Brad Miller, OF/1B Logan Morrison and RHP Danny Farquhar.
Karns is the biggest piece in this deal for the M's and arguably the best player changing hands. The right-hander went 7-5 with a 3.67 ERA over 147 innings with the Rays in 2015, striking out nearly a batter per inning. The 27-year-old will strengthen a Mariners rotation that already includes Felix Hernandez, Hisashi Iwakuma and Taijuan Walker. Nov 5 - 9:01 PM

Nate Karns (forearm) expects to have a normal winter.

Karns was shut down a couple weeks early with a mild forearm strain, but it shouldn't affect his offseason routine. The 27-year-old right-hander posted an impressive 3.67 ERA, 1.28 WHIP, and 145/56 K/BB ratio in 147 innings this summer for the Rays and should have a rotation spot all locked up for 2016.

Nate Karns has been shut down for the rest of 2015 with a mild forearm strain.

Karns was already moved to the Tampa Bay bullpen on September 2 after showing signs of fatigue. The 27-year-old right-hander will finish with a 3.67 ERA, 1.28 WHIP, and 145/56 K/BB ratio in 147 innings.
Sep 22 - 5:23 PM

The Rays have demoted Nate Karns to the bullpen.

It was either going to be him or Erasmo Ramirez that made room for Matt Moore's return, and Karns winds up being the unlucky one. Karns has pitched well overall this season with a 3.69 ERA and nearly a strikeout per inning, but he could be wearing down a bit given his 4.97 ERA in August. Moore will rejoin the rotation on Saturday in New York.
Sep 2 - 3:49 PM

Nate Karns gave up two runs in five innings, taking a no-decision in Sunday's win versus the Royals.

Both runs scored in the third when Ben Zobrist and Lorenzo Cain each hit run-scoring singles. Karns gave up six hits and a walk while striking out five on the afternoon. The right-hander hasn't been able to pitch deep into games lately, reaching the sixth inning only once in his last five starts. Nevertheless, he carries a productive 3.69 ERA with a 1.27 WHIP and a 141/55 K/BB ratio over 144 innings. Karns will face the Yankees on the road in his next outing.
Aug 30 - 4:33 PM

Nate Karns allowed five runs over three innings in Tuesday's no-decision against the Twins.

Karns was done in by walks, issuing four free passes on the night, two of which came around to score. One big swing by Miguel Sano in the first inning also accounted for three of the runs. Karns' struggles haven't been the norm this year, as he is 7-5 with a 3.69 ERA and 1.27 WHIP through 25 starts. The right-hander will meet the Royals on Sunday.
Aug 25 - 11:17 PM

Rays manager Kevin Cash said there are no plans to shut down Nate Karns.

Karns is at 136 innings going into Tuesday's start. He threw 157 1/3 innings last season between the majors and the minors, so there shouldn't be any restrictions with his workload down the stretch. "Right now I feel great," said Karns, who has a 3.44 ERA this season. "I’m in a rhythm. I’m ready to push through. If the team needs me to go 200 innings this year, I feel like I’m ready for it."
Aug 25 - 11:32 AM

Nate Karns fanned eight while holding the Astros to one run over six innings on Wednesday.

Carlos Correa's first-inning homer was the only damage. It's the fifth time in six starts since the All-Star break that Karns has allowed two runs or fewer. He has a 3.44 ERA and a 133/50 K/BB ratio in 136 innings.
Aug 20 - 12:29 AM

Nathan Karns mostly kept the Rangers off the scoreboard in Friday's no-decision, allowing two runs on two hits over 4 2/3 innings

Karns was his own worst enemy on Friday, walking five. It's a wonder the Rangers didn't cash in on the free passes. As is, runs came home on a double play grounder by Adrian Beltre and a solo home run by Josh Hamilton in the first and second innings, respectively. Karns is the owner of a 3.53 ERA and 1.24 WHIP. He's allowed two or fewer runs in 17 of his 22 starts and will try to add to that impressive tally when he heads home to face off with the Twins in his next start.
Aug 15 - 1:37 AM

Nate Karns pitched well, allowing two runs in 5 1/3 innings, but got a no-decision as the Rays rallied late to overcome the White Sox on Monday.

Karns was working on a shutout until Jose Abreu bashed a two-run home run in the sixth inning, chasing the right-hander from the game. He gave up only three hits and a pair of walks while striking out seven. Karns has limited the opposition to two or fewer runs in 16 of 21 starts, resulting in a 3.37 ERA, a 1.20 WHIP, and a 113/42 K/BB ratio over 120 1/3 innings. He'll do battle with the Mets at home next.
Aug 4 - 12:07 AM

Nathan Karns will make his next start on Monday against the White Sox.

He gets moved back a day as Jake Odorizzi will take the hill on Sunday against the Red Sox. It's a tough blow for fantasy owners in weekly formats who used Karns this week, as he loses a double, though it's made up next week with the White Sox and Mets on tap.
Aug 1 - 11:37 AM

Jeff Passan of Yahoo Sports reports that the Rays are listening to offers for Nate Karns.

Passan says Karns is drawing interest "from a number of teams," and rightly so. The 27-year-old right-hander has posted an impressive 3.37 ERA, 1.21 WHIP, and 106/40 K/BB ratio across 115 innings this season for Tampa Bay and he is under contractual control through 2020. It'll probably take a big return for the Rays to move him.
Jul 30 - 11:21 AM

Nate Karns got the win on Monday against the Tigers after limiting them to a lone run in six innings of work.

Karns tossed six shutout innings, but allowed a leadoff home run to Yoenis Cespedes in the seventh. Victor Martinez added a single before the right-hander was lifted. They were two of three hits he allowed on the night with no walks and three strikeouts. Karns has limited the opposition to two or fewer runs in seven of his last eight starts and now boasts a 3.37 ERA with a 1.21 WHIP and a 106/40 K/BB ratio over 115 innings. He'll face the Red Sox at Fenway Park next.
Jul 27 - 10:54 PM

Nate Karns threw five shutout innings and hit a solo home run, leading the Rays to a 1-0 victory over the Phillies on Tuesday.

Karns provided the game's only offense when he drilled an Aaron Nola offering over the fence in left field. Meanwhile, he limited the Phillies to three hits and two walks while striking out four in his five innings of work. The right-hander lowered his ERA to 3.47 and has a 1.25 WHIP and a 103/40 K/BB ratio over 109 innings along with it. Karns will host the Tigers in his next start.
Jul 21 - 10:06 PM

Nathan Karns struggled in Thursday afternoon's loss to the Royals, surrendering seven runs on nine hits over six innings.

Four of the seven runs came home via two-run homers by Lorenzo Cain and Salvador Perez in the first and fifth innings, respectively. Karns' lackluster start comes on the heels of a 10-strikeout performance against the Yankees. He's now the owner of a 3.63 ERA and 1.26 WHIP in what's been a solid season to this point, Thursday's outing notwithstanding.
