Giants vs Diamondbacks prediction
My Giants vs Diamondbacks best bet: Ketel Marte Over 1.5 total bases (+130 at bet365)
⚾ Pick Analysis
Ketel Marte mashes right-handed pitching. He has averaged 2.2 total bases per game when facing a right-handed starter, and his numbers are exceptional across the board.
Marte owns a .316 batting average vs. righties while leading the Arizona Diamondbacks in wOBA and barrel rate.
The Diamondbacks rank third in runs per game, and can keep up with anybody offensively, so sporting the best numbers on the team against right-handed pitchers is no small feat.
He has a nice matchup against Landen Roupp, who has not fared well against left-handed bats, especially on the road.
Roupp owns a 5.06 SIERA and has given up a .271 average in road games vs. lefties, which is notable as Roupp plays in a very pitcher-friendly park at home.
Chase Field is one of the best ballparks in the majors for offense. Facing a switch hitter who has dominated right-handed pitching all season long, Roupp is likely to have problems with Marte.
Giants vs Diamondbacks same-game parlay (SGP)
Ketel Marte Over 1.5 total bases
Ketel Marte Over 0.5 runs
Heliot Ramos Over 1.5 total bases
🚀 SGP Analysis
Marte has scored at least one run in 59% of his games this season. That number grows to 64% when isolating home dates against right-handed pitchers. If he gets into scoring position, there’s a good chance somebody in this loaded Diamondbacks offense will drive him home.
Heliot Ramos has averaged 2.3 bases over his last 14 meetings with Arizona and should benefit from playing in such a good hitting environment.
