Your friendly neighborhood @Roto_Dubs is back with his weekly starting pitcher matchups. Below are the projected starting pitching matchups for Week 21, and will be updated as more starters are announced. If you've got any questions about which pitchers can capitalize on a juicy matchup and which ones might be worth putting on the pine against a fierce offense, this is the weekly piece for you.
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 to hopefully find some hidden gems to bolster your teams.
This weekly piece considers the pitcher’s opponents, their career stats against the opponent, 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.
