Hi everyone, I'm having huge problems picking winners last couple of weeks... Maybe I gave waaaay to much attention to starting pitchers and waaaay to little to relievers...
SO this is why I try to figure sth out based on a whole bunch of stats.
I made a ranking system for the offense based on Runs/Plate app., BB/K, Batting Average, Slugging%, wOBA. Giving me a certain % for every team
Next I made a similar ranking for relievers based on IP/Game, K/BB, HR/9, Batting average against, WHIP, ERA, FIP, XFIP and SIERA
The last thing i did was a starting pitching ranking for today with about the same stats as the relievers.
Oh yes... I only used stats of last 5 games for Starting pitchers, Last 14 days for relievers and last 7 for offenses. As I believe stats from the start of the season doesn't matter anymore today.
This is an example how i did it for the Nationals - Rockies game:
Washington vs Colorado Haren: 50.85% - Chacin: 32.48% Wash Off.: 46.67% - Col off.: 37.33% Wash BP: 74.81% - Col BP: 24.81%
Washington Average%: 57.44% - Colorado Average: 31.54% So a 25.9% edge for Washington
What do you guys think. IF you want I can post these %'s for every game

Be careful with this theory. While it makes sense to weigh recent performance more heavily than performance 2 months ago (or 2 year ago), exclusively using this data will produce extreme results due to its small sample size. Baseball probabilities take time to be realized. For pitchers, it will take ~50 IP to start achieving normalized results. For batters, it takes 400 PA.
