Marlins vs. Mariners Best Prop Bet

• J.P. Crawford OVER 1.5 Total Bases (+250) via FanDuel

In today's edition of "Walk-Off Wagers", I broke down why I'm betting on J.P. Crawford to have a big game:

J.P. Crawford has got off to a strong start for the Seattle Mariners this season, racking up 20 hits in 25 games for a batting average of .263 and an on-base percentage of .398, the best mark on the team amongst players who have made at least 11+ appearances.

Tonight, he and the Mariners will face Connor Gillispie of the Marlins, who has an ERA og 6.75 and a WHIP of 1.417 on the season. All we need is for Crawford to record at least two total bases tonight, and we'll cash this +250 ticket.

Marlins vs. Mariners Prediction and Pick

The OVER cashed in last night's interleague matchup, and I'm going to bet on a similar result tonight. These two offenses have been two of the hottest in the Majors. Over the past 14 days, the Mariners rank third in the Majors in OPS, and the Marlins are right behind them, coming in at fifth in that stat. The Marlins are also third in batting average over the past 14 days at .286.

On top of the hot offenses, neither starting pitcher has had a good start to their respective seasons. Connor Gillispie of the Marlins has an ERA of 6.75, and Luis Castillo has a disappointing ERA of 4.44.

All signs point to tonight being another high-scoring affair.

Pick: OVER 7.5 (-118)
