What’s up RotoBallers. Below are all of the projected starting pitching matchups for Week 6, including our recommendation on whether to start or sit them for your fantasy baseball teams. Next to each matchup below, we also have a link to our Premium Starting Pitcher Daily Matchups, Streamers & DFS Tool. For those who aren't aware, our in-house tool analyzes SP matchups based on a variety of stats/metrics, and recommends whether start, sit, or stream any pitcher for seasonal and DFS leagues. It's pretty cool.

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. This week there are a bunch of nice two-start pitchers including Greinke, Lester, Scherzer, Strasburg, Cole, DeGrom and Arrieta to name a few. As always, there are also viable starting pitcher sleepers and streamers to consider off the waiver wire (Syndergaard, Duffy, Leake, Quintana, Peralta, Lincecum, Harang, Chavez), depending on your league size and format including AL-Only and NL-Only leagues.

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 all of the pitching performances thus far this season, 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.

SP Matchups & Start/Sit Recommendations

Editor’s Note: RotoBaller’s fantasy baseball waiver wire pickups list is updated every single day. Our awesome writers bring you analysis on hot or emerging starting pitchers, and also all other fantasy positions. You can also download our waiver wire iPhone app for free, and easily stay updated.

As always, projected starters and matchups may change throughout the week:
