Key Storylines
Pitching matchup: Sandy Alcantara (9-12, 5.53 ERA) will take the mound for the Marlins. Despite a challenging season, Alcantara has shown flashes of the pitcher who previously won the NL Cy Young award. He will look to capitalize on the Rockies’ offensive struggles in this game. Tanner Gordon (6-6, 6.14 ERA) will start for Colorado. The Rockies have won five of the last six games that Gordon has started and will look for another win here.
Key Players: Xavier Edwards leads the Marlins with a .280 batting average and will be a key part of the Marlins lineup here. Otto Lopez has driven in 74 runs and has taken over the lead in that category for Miami. Eric Wagaman is on a five-game hitting streak, batting .556 during that stretch. The Rockies will rely on Hunter Goodman, who has 30 home runs and 87 RBI this season.
Recent team streaks: The Marlins have won four of their last five games and have won the last two games in this series. The Rockies have struggled, winning only one of their last 10 games coming into this interleague matchup.

Final Thoughts
The Marlins have been far from convincing so far this year. But any team looks convincing when taking on the Colorado Rockies. Miami has won the first two games of this series and should complete a three-game sweep in Denver on Thursday afternoon. But my best bet for this game is for it to go over the total, thanks to the struggles of both Alcantara and Gordon on the mound.
