Best MLB Same Game Parlay Bet for Wednesday 4/16/25

Major League Baseball is a sport perfectly suited for same game parlays.

Not only do we have abundant options across the traditional markets and props for both pitchers and hitters, but plenty of those bets correlate well. Given parlays require all legs to hit, that cohesion is key.

Which SGP stands out to me tonight?

Let's dig into the Seattle Mariners at the Cincinnati Reds and lay out where I'm seeing value in FanDuel Sportsbook's MLB betting odds.

Today's Best MLB SGP for Mariners at Reds

Leg 1: Under 8.5 Runs (-104)

As boring as it may be to start things off, this one centers primarily around the weather.

First-pitch temperature in Cincinnati tonight will be 58 degrees. That's a downgrade from baseline there, and I'd have the total at 8.48 runs if the temperature were closer to normal.

Both teams have non-threatening offenses, solid starters, and decent bullpens, so I don't mind starting things with the under even if it isn't the most thrilling leg.

Leg 2: Nick Martinez Over 5.5 Strikeouts (+114)

This is one of my three favorite strikeout props of the day, and it correlates with the under.

Nick Martinez has a respectable 21.7% strikeout rate since rejoining the rotation last year. The Reds are willing to let him pitch deep in games, too, as he went 107 pitches in a start late last year and has been at 92 and 93 in his past two outings.

Put that at home against a Mariners lineup with a 26.8% strikeout rate against righties since the start of last year, and I've got Martinez projected to clear the 5.5-strikeout mark tonight.

Leg 3: Bryce Miller Under 5.5 Strikeouts (-125)

We don't talk about park factors for strikeouts much, but given the difference in batter's eyes and other elements, they do matter. They're working against Bryce Miller tonight.

That's not to say that Great American Ball Park is a negative for strikeouts. It's about neutral, per Baseball Savant, keeping us on Martinez's over.

It's more about forcing Miller to leave T-Mobile Park, which is the best venue for strikeouts in the league. We can see the impact of this in Miller's career splits as he has a 26.2% strikeout rate at home and a 19.5% clip on the road.

That gap will tighten as the sample expands, so I've got Miller's projected strikeout rate -- considering matchup, park, form, etc -- at 23.6%. Even with that, his strikeout projection settles in at 5.32.

Pitchers projected for 5.32 strikeouts have gone under 5.5 at a clip of 60.9% for me, putting me on Miller's under as the final leg of our parlay.
