Yankees vs. Blue Jays Best Home Run Bet
Best Bet: Vladimir Guerrero Jr. Home Run (+450) odds via BetOnline

Back to back days leaving the yard? Can Vladimir Guerrero Jr. deliver for us?
Vladimir Guerrero Jr. enters Monday in top form, batting .281 with a .884 OPS in June and crushing left-handed pitching all season. At home against southpaws, he owns a 1.086 OPS and 202 wRC+, and today he draws Carlos Rodon—someone he is 8-for-12 against with a homer and two doubles.
Rodon leans on the fastball and slider, both pitches Guerrero dominates better than anyone in the Blue Jays lineup. This is a strong matchup for a ball to leave the yard.

Giants vs. Diamondbacks Best Home Run Bet
Best Bet: Rafael Devers Home Run (+330) odds via BetOnline

Are we due for a big game from Rafael Devers?
Rafael Devers draws a strong matchup against Ryne Nelson, who ranks near the bottom in pitcher ratings on Batters-Box and struggles in key power metrics.
Nelson throws fastballs 61% of the time, and Devers leads the Giants in production against that pitch—owning a +8 run value, .944 OPS, and 175 wRC+. He also profiles well against Nelson's cutter and has handled the rest of his arsenal with ease. After back-to-back hitless games, Devers is in a prime spot to bounce back with a long ball in Arizona.
