Johnson was claimed off waivers by the Giants on Wednesday. Once considered a top pitching prospect in the Cubs' organization, Johnson was designated for assignment last week after posting a 4.31 ERA, 1.45 WHIP and 74:27 K:BB with Triple-A Iowa this season (his first working almost exclusively out of the bullpen). With this move, Johnson goes onto the Giants' 40-man roster, but it's uncertain if they have plans to use him at the big-league level over the final 11 days of the campaign.
Johnson was designated for assignment by the Cubs on Wednesday. Johnson was dropped from the 40-man roster to open a spot for the contract selection of Thursday's starter, Jen-Ho Tseng. He was never able to get things going at Triple-A Iowa, compiling a 5.29 ERA and 1.55 WHIP in 117.1 innings there over the past two seasons.
Johnson was optioned to Triple-A Iowa on Sunday. Johnson was brought up from Iowa prior to the weekend to provide an extra arm out of the bullpen and made his MLB debut Friday against the Brewers, giving up two unearned runs over one inning. With the Cubs recalling Dylan Floro on Sunday to slot in as a long reliever, Johnson was sent back to Iowa in a corresponding move to see more regular reps out of the bullpen.
Johnson was recalled from Triple-A Iowa on Wednesday. Johnson was recalled to take the place of Jeimer Candelario, who was sent back to Triple-A earlier Wednesday. The 26-year-old owns a 3.21 ERA through with an impressive 13.5 K/9 through 14 innings with Iowa this season, though his 7.1 BB/9 makes his numbers a little less enticing. He should be available Wednesday against the Reds, though he likely won't see any high-leverage roles given the pedigree of arms already in the Cubs' bullpen.
Johnson was optioned to Triple-A Iowa on Friday, Gordon Wittenmyer of the Chicago Sun-Times reports. In an attempt to keep him healthy, Johnson was shifted to the bullpen full-time for the 2017 season after injuries marred his 2016 campaign. He struggled to a 6.14 ERA in 63 Triple-A innings last season, so the Cubs will likely want to see Johnson perform well there before calling him up. If he's able to keep up his 10.7 K/9 and drop his 6.1 BB/9 at Triple-A, he could find himself in the majors sometime in 2017.
