Since coming over from the Dodgers, Yarbrough has been lights out on the mound, in 31.1 innings pitched, he holds a 2.01 ERA, .M<173 BAA and a 0.80 WHIP (Walks/hits per innings pitched). Since coming over from the Dodgers, he has improved greatly, where he previously held a 3.74 ERA and 5.17 FIP in 32 relief appearances.
With his deal coming to end this offseason, he will have a good amount of leverage to want to test his value in the open market, but the Blue Jays need to make a push to try and sign him before there is a chance for that to happen. The Jays bullpen has been the weakest aspect of their team this season, and when you find an arm like his, you cannot pass it up.
