Nathan Karns (back) played catch with the trainer on Wednesday.

Karns has been on the shelf since the end of July due to a muscle strain in his lower back. He is hoping for a return before the end of the regular season, but that could be a reach -- the 28-year-old right-hander will not be eligible to return from the 60-day disabled list until September 29. The season wraps on October 2.
Sep 7 - 6:01 PM

Nathan Karns (back) still hopes to return before the end of the season.

Karns was recently transferred to the 60-day disabled list, so he won't be eligible to return until September 29. The regular season ends on September 2, so it could be a stretch for him to make a contribution. Karns has been out since July 29 with a muscle strain in his lower back.
Sep 6 - 10:32 AM

Mariners transferred RHP Nate Karns from the 15-day disabled list to the 60-day disabled list.

The move clears the way for Evan Scribner's return. Karns is now effectively ruled out for the season with a lower back strain, as he will finish with a disappointing 5.15 ERA in his first season in Seattle.
Sep 1 - 4:05 PM

Nate Karns (back) hasn't resumed throwing.

Karns claims to be feeling better but there's still no timetable for his return. The right-hander was moved to the bullpen in June but Mariners GM Jerry Dipoto said the team plans to use him as a starter going forward. Karns has gone 6-2 with a 5.15 ERA in his first year with Seattle.
Aug 18 - 8:22 PM

Mariners general manager Jerry Dipoto said Monday that the team plans to stretch Nate Karns (back) out as a starter.

Karns was moved to the bullpen at the end of June, but Dipoto said the Mariners didn't see the velocity spike they were hoping for and are ready to abandon the experiment. The 29-year-old hit the disabled list over the weekend with a lower back strain, but he'll be brought back as a starter when he's ready.
Aug 1 - 8:41 PM

Mariners placed RHP Nate Karns on the 15-day disabled list with a lower back strain.

The right-hander has lost all fantasy relevance since his demotion to the bullpen, so this isn't major news. He should be ready to rejoin the M's bullpen in mid-August.
Jul 30 - 12:26 PM

Nate Karns earned his first save Saturday since being demoted to the bullpen.

With an eight-run lead after six innings, the Mariners asked Karns to pitch the last three frames. He gave up a pair of runs on a homer by Chris Davis. Karns was only credited with a save because he closed out the blowout game after pitching three innings. Karns is not a threat to steal closer Steve Cishek's job any time soon.
Jul 3 - 2:30 AM

In his first appearance after being moved to the pen, Nate Karns struck out six in two scoreless innings Wednesday against the Pirates.

Karns still looked like one of the Mariners' five-best starters even with his modestly disappointing start this year, but tonight showed why the move to the pen could work out anyway. The team could finish the year with Karns and Edwin Diaz as its two best relievers.
Jun 30 - 1:36 AM

Mariners manager Scott Servais announced Tuesday that Nate Karns has been moved to the bullpen.

Karns has struggled in the M's rotation this season, compiling a 4.56 ERA, 1.46 WHIP and 84/38 K/BB ratio across 81 innings. He has terrific stuff, but has gotten into trouble due to an extremely high walk rate (4.2 BB/9) this season. It'll be interesting to see if its a temporary move until he rights the ship, or if the M's believe his future is as a late-inning reliever.
Jun 28 - 7:20 PM

Nate Karns surrendered four runs on five hits and two walks while striking out three in five innings, leading the Mariners to a 5-4 victory over the Cardinals on Saturday.

He did not pitch very well but snared a win anyway. The big blow was a 5th-inning, three-run home run by Aledmys Diaz that ruined what had been a very effective outing up to that point. The poor game boosts Karns' ERA up to 4.56 on the season. He strikes out a lot of batters (9.33 K/9) but spoils that by walking too many (4.22 BB/9). He will face the Orioles in his next start on Friday in Seattle.
Jun 26 - 2:21 AM

Nate Karns allowed five runs on seven hits over five innings against the Tigers on Monday.

Karns struck out six while walking three, and he served up a two-run home run to Miguel Cabrera among his seven hits allowed. He's given up just seven home runs in 14 starts this year, a step forward after allowing 19 dingers last season. The right-hander is still winless in the month of June and is 5-1 with a 4.38 ERA and 1.46 WHIP overall. He'll square off with the Cardinals in an interleague tilt Saturday.
Jun 20 - 11:51 PM

Nate Karns took a no-decision against his former team the Rays on Wednesday after striking out eight batters in five innings, allowing two runs on two walks and four hits.

Karns has fanned a batter per inning in his career, but his high walk rate has held him back. This year Karns sits on a 5-2 record with a 4.06 ERA and inflated 1.42 WHIP. He lines up for two starts next week, facing the Tigers and Cardinals.
Jun 16 - 12:47 AM

Nathan Karns struggled mightily with his control in taking a no-decision against the Indians on Thursday, walking five and allowing one run over 4 1/3 innings.

Karns has now walked five in each of his last two starts. On Thursday, he threw just 55 of his 92 pitches for strikes. He allowed just two hits, but was his own worst enemy otherwise. Through 12 starts covering 66 innings, he holds a 4.09 ERA, 1.44 WHIP and 67/31 K/BB ratio. His strikeout rate is shiny enough, but his less desirable tendency to allow runners on base makes him something of a fantasy adventure for those willing to take the plunge in deeper AL-only formats. A road date with the Rays shows next on his schedule.
Jun 10 - 1:49 AM

Nate Karns was pounded by the Texas Rangers on Saturday, giving up seven runs -- all earned -- while giving up eight hits and five walks in four innings in the loss.

Karns managed to whiff five batters but saw his ERA rise from 3.43 to 4.23 tonight. Karns pitched into the fifth but was removed before getting an out. He gave up runs in every inning but one. Karns struggled with his control and when he did manage to get it over the plate the Rangers got hits in key situations. His record falls to 5-2.
