Johnson was designated for assignment Friday. Johnson's been lit up lately, giving up seven earned runs over his last 5.1 innings (11.81 ERA), which is a likely reason why Seattle is sending him on assignment. In corresponding roster moves, Jonathan Aro and David Rollins were called up. Johnson will presumably head to Triple-A Tacoma now where he began 2016, repossessing a 2.25 ERA and 0.75 WHIP through 16 innings.
Johnson was lit up for three earned runs on four hits in one inning of work against the Padres on Wednesday. It wasn't a great day for Seattle pitchers, as they combined to allow 14 runs on 19 hits, yet it was particularly bad for Johnson. His ERA rose from 0.79 to 2.92 after his worst outing this season. Nonetheless, Johnson has been a great addition to the Mariners, he has allowed just four runs in twelve innings of work (including Wednesday's appearance) and seems to be a staple in the bullpen.
Johnson had his contract selected by the Mariners on Tuesday. Johnson landed with the Mariners' organization after being released by the Rangers this offseason and has seen strong results with Triple-A Tacoma so far, registering a 2.25 ERA and 20 strikeouts in 16 innings. He is likely to occupy a middle relief role for the Mariners going forward.
Johnson was released by the Rangers on Monday, TR Sullivan of MLB.com reports. Johnson struggled to a 10.13 ERA in six appearances for the Orioles last season and has apparently failed to impress at the lower levels, despite posting a 2.30 ERA across 54.2 Triple-A innings in 2015. The 28-year-old will look to catch on with another team seeking organizational depth.
Johnson signed a minor league contract with the Rangers on Friday that includes an invitation to spring training, Roch Kubatko of MASN reports. Johnson was designated for assignment on December 2 by the Orioles after Mark Trumbo was acquired, and the Rangers became the team to ultimately pounce on the right-hander. The 25-year-old primarily pitched with Triple-A Norfolk last season, posting a 2.30 ERA and 11.1 K/9 in 54.2 innings with the Tides, but also had two rough appearances with Baltimore. Johnson will compete for a spot in the Rangers bullpen during spring training if he can get major league hitters out consistently.
