Cubs signed RHP Trent Thornton to a minor league contract with an invitation to spring training

The move was announced by Tread Athletics, where Thornton has been training this offseason. He spent the last three seasons with the Mariners posting a 3.65 ERA in 140 2/3 innings. He tore his Achilles in August but was reportedly up to 93 mph on his fastball in a pro day workout and looking healthy. If he is healthy, he has a chance to win a spot in Chicago’s bullpen.
