Chad Green
Green is having an excellent season in his first full season since returning from Tommy John, (1.51 ERA, 0.84 WHIP, opponent average of .165 and converted all 9 of his save opportunities.) He's thrived in the closer's role since Yimi Garcia was traded to the Mariners. It was reported by Jon Morosi that Green's former team the Yankees were interested in a reunion, due to Green's ability pitching in high leverage situations. This reunion failed to materialize as the Yankees ended up trading for veteran reliever Mark Leiter Jr. from the Cubs.
Like Bichette, the Blue Jays haven't ruled out a return for Jordan Romano who had surgery a month ago on his right elbow. In the meantime, Green will remain the closer. If Romano returns this season and Green continues to excel, there's a high chance he'll one of the best relievers on the trade market.
