It used to be that the Orioles leaned heavily on Jeremy Guthrie and four no-name pitchers to build their starting rotation.
However, after a breakout 2012 campaign for the staff, they are loaded with depth when it comes to the final spot for 2013.
The leading candidate coming in was Johnson, and he's done nothing to lose the job this spring.
Entering Tuesday, he had appeared in three games, giving up one hit while striking out three and walking two. That line can be knocked down, considering he's faced mostly minor league competition according to Baseball-Reference.com's new opponent quality scale for spring training.
Outside of Johnson, the other candidates for the fifth starter have struggled.
Brian Matusz was the fourth overall pick in 2008, but has struggled in the major leagues throughout his career until being converted to a left-handed specialist last year. With a 1.35 ERA and 0.60 WHIP as a reliever last year, he will probably return to the bullpen.
Jake Arrieta was the team's opening day starter in 2012, but spent most of the year working on his mechanics. When he's on his game, he's the best strikeout pitcher the Orioles have. However, that doesn't happen too often.
The Orioles had also picked up Jair Jurrjens on a minor-league deal last winter, but he hasn't shown the same talent that he had before several injuries derailed his career with the Atlanta Braves.
Zach Britton may be the only Oriole out of the group behind Johnson that's having a decent spring, but it seems like Johnson has been doing enough to fend him off.
