Thornton has been informed that he has made the Opening Day roster, Dennis Lin of the San Diego Union-Tribune reports.

EDGE Analysis

Thornton was a late addition to the team after signing a minor league deal in March, but despite struggling in the spring to the tune of a 12.00 ERA in seven outings, he'll join the bullpen to begin the year. The 39-year-old had one of his better seasons in 2015 with the Nationals, posting a 2.18 ERA in 41.1 innings, and could be a decent source of holds.
