Week 20 Starts & Sits - All Starting Pitcher Matchups

Nick Mariano's recommended fantasy baseball starts and sits for all Week 20 starting pitcher matchups. Unearth potential streamers, two-start SPs and sleepers.

You better not be tiring yet, August means we're nearing those pennant weeks. Make sure you stay aware of your weekly inning minimums and seasonal inning maximums. To usher you towards the championship, we here at RotoBaller offer our analysis and dynamic pitching scores for each matchup to frame your start/sit decisions. In case you missed it, this is our sixth year now writing this weekly column, helping fantasy baseball managers pick the best pitchers weekly.

Below are the projected starting pitching matchups for Week 20 -- August 12th through August 18th -- which will be updated as rotations are announced and tweaked. This column will be continuously updated and adjusted for any postponements or rotation shuffles, reflecting official beat writer speculation for as many unconfirmed rotation slots as possible.

For every week of the fantasy baseball season, we look to analyze all of the projected starting pitcher matchups and put together our optimal lineups. Here at RotoBaller, we believe that it’s key to analyze every SP matchup, each and every week, to help determine which SPs to start/sit and identify some sneaky streams. Let's win some leagues!

Be sure to check all of our fantasy baseball draft tools and resources:

 

SP Matchups & Start/Sit Recommendations

This weekly piece considers the pitcher’s opponents, their outlook against lefties and righties, some ballpark factors and historical splits. With all of this information, we then provide our start/sit recommendations for each starting pitcher matchup for the approaching week of fantasy baseball.

Score values typically range from about 40-60, with higher values being superior. A 50 is the theoretical "Start/Sit" cutoff, but you should use the color-coded scores for valuable context to make your own decisions. Streamers and those relying on counting stats more than all-around ratios can target 48s and 49s, for example. Those set for two-start weeks are highlighted in yellow. Openers will have an asterisk if no "true" starter is announced by team beat writers.

This column will be updated daily as more rotations and starters are announced through August 4th.
