Kevin Herget: Everything you need to know

Herget signed a minor league contract that includes an invitation to spring training with the Mets on Thursday, Will Sammon of The Athletic reports. Herget was designated for assignment by the Mets in late September and became a free agent a few days later. He's now back with the club and will battle for a spot in the team's bullpen during spring training.

Herget elected free agency Monday. Herget was booted from the Mets' 40-man roster Saturday, and rather than accept an assignment in the minors, he'll test the open market. He appeared in seven games across stops with Atlanta and New York during the regular season, posting a 2.77 ERA and 1.31 WHIP across 13.0 innings.

The Mets designated Herget for assignment Saturday. Herget will lose his spot on the active and 40-man roster, opening a spot for Dylan Ross to join the big-league club. Since being picked up by the Mets in mid-July, Herget allowed three runs and a 5:3 K:BB across 10 big-league innings.
