Simon will likely slot into the Reds' rotation to begin the season, alongside younger candidates like Anthony DeSclafini, Raisel Iglesias, John Lamb, Jon Moscot and Brandon Finnegan. Cincinnati has an immediate need in its rotation due to a recent injury to Michael Lorenzen, who is dealing with elbow trouble and will likely miss significant time.
Simon, 34, drew interest from a couple of teams this winter, with the Marlins showing the most consistent interest dating back to the Winter Meetings. He spent last season with the Tigers, posting a 13-12 record and 5.05 ERA after being acquired in a trade with the Reds in December of 2014.
Simon spent three seasons with the Reds from 2012 to 2014, posting a 24-16 record and 3.16 ERA in that span while being named to the NL All-Star team in his last season in Cincinnati. He is the owner of a lifetime 45-40 record and 4.17 ERA in eight major-league seasons with the Orioles (2008-11), Reds (2012-14), Tigers (2015).
