Scoring hasn’t been an issue for both teams this season with the Cardinals and the Marlins having shown the ability to put runs on the board in different ways and pressure their opponents. The Marlins, in particular, have slowly made themselves one of the lethal teams on the offensive end of the floor with Xavier Edwards and Liam Hicks delivering key contributions across multiple ends on the floor. The 26-year old Edwards already has 28 hits and six RBIs this season and we are expecting him to make an impact here given how the Cardinals’ pitching has been tested in stretches when they allow traffic on the bases.

The Cardinals, for their part, have relied solely on right fielder Jordan Walker to deliver all the goods with the 23-year old youngster recording 25 hits, 16 RBIs, and six home runs this season. Look for Walker to potentially increase his hits tally here although the Cardinals shouldn’t be too dependent on him to carry the whole offense. That’s because the Marlins, for all the flak they have been getting, have actually been pretty decent defensively especially when they limit walks and avoid putting extra runners on base. This too is the reason why we are giving the Marlins a slight edge here to pull away in the later innings.
