Kolarek was signed by the Orioles following his release from the Mets in early October, Matt Eddy of Baseball America reports.
Kolarek, who pitched with Double-A Binghamton in 2015, improved upon his dreadful 2014 numbers (6.07 ERA, 1.75 WHIP in 56.1 innings), but not by much, posting a 4.43 ERA and 1.30 WHIP in 67 innings with the Double-A affiliate this season and was subsequently released. He will now try to climb the minor league ladder with the Orioles.
