There is too much value to pass up on this game. 
Toronto starter Jacob Waguespack has had some good moments. Just three starts ago he held the powerful Dodgers to no runs in seven innings allowing just one hit and one walk with five strikeouts. He has a respectable 3.97 ERA. 
Tyler Glasnow will be making his first appearance for the Rays since May 10. He's been out this long due to a strained forearm. Glasnow has a very high ceiling, but he figures to be rusty and only pitch around two innings turning this into a bullpen game for the Rays. 
That puts a lot of randomness into the equation and makes the Blue Jays an enticing underdog at this huge plus price.
