The current betting odds have the Marlins listed as a slight underdog in this game according to Draftkings Sportsbook. The Phillies have looked good in their games this season with their 68-58 record overall which has them right near the top of the NL East. They have looked good in their own ballpark too with their 33-30 home record this season. Meanwhile, the Marlins have looked good in their games this season with their 64-62 record overall which has them right in the middle of the NL East. They haven't been a good road team though with their 26-37 road record this year. The Phillies are 6-4 in their last 10 games and have been rolling lately, but the Marlins are also 6-4 in their last 10 games, fighting for that last Wild Card spot in the NL. The Marlins are going to have the better pitching matchup in this one too and it might be their best chance to take a game in this series. The Marlins are going with Alcantara in this one and he has looked good this season. He is 13-7 with a 3.43 ERA and he hasn't been giving up many runs. He is coming off another good start giving up 1 earned run which has been a common theme for him and the team has been having a lot of success with him lately, winning 3 of their last 4 games with him starting. The Phillies are going with Nola in this one and he hasn't looked great this season. He is 4-9 with a 5.33 ERA and he has been giving up quite a few runs all year. He is coming off a good start in which he gave up 1 earned run and the team has won 2 of their last 3 games with him starting too, but that hasn't been a common theme for him this season. The Marlins don't have a bad offense either, so look for them to take advantage of this pitching matchup and keep themselves in the Wild Card race. The best way to place a bet here is on the Marlins to win this game.

"Once they [called] out there, I can't go argue a play that went to New York. My only point was that I get it, but with two outs, with the size of the lead Otto's going to have there not being held on and going on contact, where that ball was going to end up, I think that he was going to score anyway. Just a little bit more frustration that you see the call's going to get overturned and think what could have been. But again, I think back more to the chances we had, a run or two that we maybe gave them." - Clayton McCullough after his team’s loss against the Phillies in their game on Monday. 

"I wouldn't have been shocked if they gave it to them. But I'm glad they didn't." - Don Mattingly after his team’s win against the Marlins in their game on Monday.
