Simon has reached agreement on a major league contract to rejoin the Reds, Ken Rosenthal of FOX Sports reports.

EDGE Analysis

Simon was with the Reds from 2012 to 2014, most notably posting a 15-10 record, 3.44 ERA and 1.21 WHIP in his final season with the team. He then struggled to the tune of a 5.05 ERA and 1.44 WHIP in 2015 for the Tigers, saying afterward that his poor performance was partially the result of a chronic knee condition that's commonly known as jumper's knee. The 34-year-old Simon may still have time to compete for a rotation spot at the start of the season.
