Nathan Karns was fantastic in Tuesday's 11-1 win over the Astros, hurling seven innings of shutout ball while allowing just two hits.

Karns wasn't perfect -- he walked three -- but he flummoxed the struggling Astros nonetheless. The 28-year-old right-hander struck out six during his superlative time on the mound. With the shutout under his belt, he now holds a 3.68 ERA, 1.41 WHIP and 24/12 K/BB ratio across 22 1/3 innings (four starts). He makes for a solid rotational arm in AL-only formats. Karns will try to replicate Tuesday's result in a road showdown with the A's next time he toes the rubber.
Apr 27 - 2:20 AM

Nate Karns surrendered five runs -- four earned -- in 5 1/3 innings Thursday against the Indians.

Rajai Davis ruined Karns' day with a big three-run homer in the fifth. Even so, the Mariners had a 7-5 lead when he departed, but that was blown by Joaquin Benoit in the eighth. Karns has a 5.28 ERA after three starts, but he still looks like a pretty good option in AL-only leagues. The guy he narrowly beat out for a spot, James Paxton, has a 5.84 ERA in Triple-A, so Karns' place in the rotation is safe.
Apr 21 - 4:48 PM

Nate Karns limited the Yankees to a Brett Gardner solo homer over five innings as part of a 7-1 victory on Friday.

Karns gave up five hits and four walks while striking out seven, so he needed 101 pitches to get through his five innings of work. However, the Yankees went 0-for-8 with runners in scoring position, so they were unable to take advantage. They had their best chance to do some damage after getting the first two batters on in the fourth, but Karns responded with three straight strikeouts. We'd like to see him work deeper into games, but the 28-year-old has some appeal in mixed leagues after posting a 3.67 ERA with 8.9 K/9 last season.
Apr 15 - 11:34 PM

Nate Karns surrendered seven hits and four earned runs in the Mariners' loss to the Athletics on Saturday.

Karns only lasted five innings in his regular-season debut for the Mariners, but it was pretty emblematic of his fantasy value. He struck out six and only walked one in five innings, which is good and is why fantasy owners pay attention to him. However, he allowed seven hits, including a home run, which is unrosterable in all but the deepest of leagues. Karns benefits from a pitcher-friendly ballpark, but will need to put together a string of quality starts to avoid losing the fifth-starter role.
Apr 10 - 1:04 AM

Nate Karns struck out eight and allowed three runs over six innings in the Mariners' 8-5 win over the Rockies on Saturday.

Karns gave up just three hits and walked two on the afternoon, with a couple of well-timed hits doing more damage than he perhaps should have allowed. Even so, it was a nice final showing from the right-hander, who earned a rotation spot despite finishing Cactus League play with a 5.46 ERA. He'll have to perform better in the regular season to keep that hold on his starting job.
Apr 2 - 6:20 PM

Fresh off being named the Mariners' fifth starter, Nate Karns was charged with four runs -- two earned -- over six frames on Monday versus the Royals.

Karns permitted just five hits, recorded five strikeouts and didn't walk anyone. The right-hander has put together a 5.73 ERA during Cactus League play, basically alternating good outings with bad ones. The 28-year-old has some fantasy appeal, although he could be on a short leash with James Paxton waiting in the wings.
Mar 28 - 7:56 PM

Nate Karns has been named the Mariners' fifth starter.

He just barely beat out left-hander James Paxton for the gig. Karns, a 28-year-old right-hander, registered a 3.67 ERA, 1.28 WHIP, and 145/56 K/BB ratio in 147 innings last season for the Rays. He was traded to Seattle in November as part of the Brad Miller swap. There may be some value here in deep mixed fantasy formats.
Mar 28 - 12:30 PM

Mariners manager Scott Servais said Saturday that the battle between Nate Karns and James Paxton for the fifth spot in the rotation is "neck and neck."

"It’s very close," Servais said. "Neck and neck. They both have struggled at times. They’ve both looked OK for an inning or two here or there. It’s very close." As Servais alluded to, it's been an up-and-down spring for both hurlers, with Karns posting a 6.75 ERA and Paxton a 9.00 ERA. Both pitchers would have some fantasy league appeal if they win the job, so this competition is worth tracking.
Mar 27 - 12:58 PM

Nate Karns limited the Rangers to one run over 4 2/3 innings in a 7-1 win over the split-squad Rangers on Friday.

Karns allowed three hits and three walks while throwing just 41 out of 81 pitches for strikes, but he was able to minimize the damage. He also notched seven strikeouts. On the heels of a shaky outing from James Paxton on Thursday, Karns appears to have the edge for the fifth spot in the rotation.
Mar 18 - 7:49 PM

Nate Karns yielded three earned runs in four innings Sunday against the Reds.

Zack Cozart and Rule 5 Draft pick Jake Cave both tagged him for homers. Karns also got hit hard last Tuesday against the Royals and is currently on the outside looking in for an Opening Day roster spot. But it's still early.
Mar 13 - 7:33 PM

Nate Karns gave up five hits and two runs in three innings Tuesday against the Royals.

Karns tossed two scoreless innings in his Cactus League debut last Thursday versus the Padres, but he looked a bit shakier on Tuesday afternoon at Goodyear Ballpark. Cleveland infielder Jose Ramirez tagged him for a leadoff double in the bottom of the first inning and an RBI single in the bottom of the third. Juan Uribe also doubled off Karns, and Mike Napoli and James Ramsey both singled. Karns is competing for the final spot in the Mariners' starting rotation this spring. He'll try for better results this weekend in what could be a five-inning appearance.
Mar 8 - 5:48 PM

Nate Karns tossed two scoreless innings in his Cactus League debut Thursday against the Padres.

Karns, who was acquired from the Rays over the winter, allowed one hit and one walk while throwing 20 out of 32 pitches for strikes. He’s competing with James Paxton for the fifth spot in Seattle’s starting rotation this spring. The 28-year-old had a 3.67 ERA and 145/56 K/BB ratio over 147 innings in 2015, so he's capable of being mixed league relevant.
Mar 3 - 8:00 PM

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.

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.
