Simon entered the spring as a rotation candidate spot and started the Orioles' first spring training game but missed nine days after tweaking his groin during a night start March 18 against the New York Yankees.
In his return last Wednesday, Simon allowed six runs in two relief innings.
Simon was 4-9 with a 4.90 ERA in 23 games (16 starts) last season.
Jason Johnson in camp
Former Orioles pitcher Jason Johnson was in camp Tuesday hoping to throw in front of the Orioles and possibly earn a spot in extended spring training in Sarasota. Johnson, 38, had labrum surgery two years ago and is attempting a comeback.
The right-hander worked out for the San Francisco Giants two weeks ago and drove to Sarasota from his home in Tampa after he spoke with Orioles special assistant Brady Anderson, a former teammate of his. Johnson said after his workout that his fastball reached 90 mph.
Johnson was 34-53 with a 4.84 ERA in parts of five seasons with the Orioles from 1999 to 2003. He has pitched for eight major league teams, most recently the Los Angeles Dodgers in 2008, when he was 1-2 with a 5.22 ERA in 16 appearances (two starts).
Johnson owns a career record of 56-100 with a 4.99 ERA 255 games (221 starts). His best two major league seasons came in Baltimore. He was 10-12 with a 4.09 ERA in 2001 and went 10-10 with a 4.18 ERA in 2003. He tallied 189 innings or more in both of those years.
