Anthony Bass has been an absolute beast in the bullpen, sporting a 0.90 ERA with just six hits and one earned run through 10.0 innings, walking four batters compared to 10 strikeouts.
He has been used in high leverage situations anywhere between the six to eight-inning area and most recently gained additional fans when he came in relief against Boston two days ago and struck out Kike Hernandez and Bobby Dalbec with runners on base to keep the score tied, with the Blue Jays eventually winning in extra innings.
Zach Pop has also done well when with the Jays, allowing just two earned runs through 6.2 innings. He has given up his fair share of hits (nine) and is not striking out many batters (one) but he keeps runners off the board, sporting a 153 ERA+ and not allowing a walk so far since joining the Jays.
Pop was sent down to AAA because he was the only member in the bullpen with options available when Tim Mayza was moved off the injured list and ready to return to the big leagues. He has made one appearance with the Buffalo Bisons since the demotion, sporting a clean inning while striking out two batters.
With rosters expanding soon, Pop is one name who will likely be near the top of the list for being called back to the big leagues.
