Key Storylines

Pitching matchup

Michael McGreevy will get the start for the Cardinals in this game on the road. McGreevy is 7-3 for the season and has a 4.08 ERA. His strikeout rate is low, with just 53 strikeouts in 86 innings of work. But he will try to overcome that to deliver his team a key victory in this matchup. Justin Verlander will start this contest for the Giants. He is 3-10 but has a 3.75 ERA that is better than his record would suggest. Verlander will try to continue to bring his ERA down while delivering his team a big win tonight.

Win Probability: Cardinals 43%, Giants 57%

Final Thoughts

Both teams are in desperate need of a win here and it will be interesting to see how the pressure of this moment impacts them. Instead of relying on either side to outperform the other here, I am going to take the over in this game. McGreevy and Verlander have both had their struggles so far this year and we should see both lineups jump on them with their playoff lives on the line. This game should fall around eight or nine total runs and go over the total no matter who ends up getting the win in the Bay Area.
