Jim Johnson, 2013
The last person on the list is the closer that Britton replaced in Baltimore, that being Jim Johnson. With a pair of over 30-save seasons in 2012 and 2013, the Orioles had five straight 30-save seasons in the 2010s, an incredible feat on its own. Since 2013 is the fifth year, we'll solely be focusing on that year.
After a 51-save season and his only All-Star Game selection in 2012, Johnson was just as dominant in 2013 for the Orioles, who finished 85-77 and third in the AL East. He followed up a top-10 finish in Cy Young voting with 50 saves in 2013, finishing 63 games in total.
Johnson didn't strike out a ton of batters, averaging 7.2 strikeouts per nine that year. It didn't matter too much, as Johnson ended the season with a 2.94 ERA and 1.280 WHIP, averaging 0.6 home runs per nine and 2.3 walks per nine in 70 1/3 innings over 74 appearances.
After his two years of dominance with the Orioles, Johnson was never able to fully replicate those numbers as he bounced between five different teams from 2014 to his last season in 2018. He still goes down as one of the better closers to come through Baltimore, given his 122 saves with the team out of his 178 total.
