Daily Fantasy Strategy — June 22 — For Draftstreet

Left-handed hitters are batting just .238 off of left-handed pitchers so far this season, posting a paltry .290 wOBA, roughly 20 percent below the league average for offense.

We know that the lefty-lefty match-up is a tricky one, and I think it’s generally accepted that the righty-righty match-up is less of an issue, because a righty who can’t hit righties would probably be filtered out of the talent pool before reached the majors.

Here’s how the numbers bear out so far this season:

Match-up	% of Pas	wOBA
LHH v LHP	7.9%	0.280
RHH v RHP	37.7%	0.307
LHH v RHP	35.8%	0.318
RHH v LHP	18.6%	0.315

Of course, not all lefties are subject to significant platoon splits, for one reason or another. The problem, generally, with lefty-lefty splits is that the number of plate appearances takes a long time to build up, leaving us with a lot of noise. So take the following table, which shows the lefty-lefty hitters who have managed a wRC+ of 110 or better over 2013 and 2014 with a minimum of 100 plate appearances, with a grain of salt.

Player	LvL PA	LvL wOBA
Ben Revere	143	0.374
Joey Votto	301	0.370
Alex Gordon	327	0.370
Freddie Freeman	293	0.364
Carlos Gonzalez	221	0.358
Norichika Aoki	268	0.356
Matt Carpenter	321	0.348
Prince Fielder	325	0.346
Jason Kipnis	292	0.344
Ichiro Suzuki	199	0.338
Brandon Belt	178	0.338
Robinson Cano	386	0.337
Chase Utley	262	0.337
Will Venable	146	0.334
Curtis Granderson	152	0.332

The Daily Five
Brandon Cumpton – $9,332
I think it’s well established now that I’m a fan of using a sub-10K pitcher to pair with a high-priced pitcher if we can find value, and I think Cumpton against the Cubs is such a value. The Cubs own the No. 29 offense against right-handed pitchers, posting a .289 wOBA with a 22.5 percent strikeout rate, while Cumpton’s been the victim of some BABIP and stranding issues, lowering his price tag. The ceiling isn’t immense with his strikeout profile, but at this price you just need six decent innings to profit.

Tanner Roark – $16,456
At this point, I’m riding the anti-Braves train against righties until it comes back to bite me. A 22.3 percent strikeout rate, a .293 wOBA, four regulars all with a wRC+ of 70 or below against righties, and so on. Roark, meanwhile, has done a great job limiting free passes and strikes just enough batters out to matter. Bookmakers agree here, setting an over/under of 7 with the Nationals as favorites.

Rockies stack – The 10.5 over/under is a full two runs higher than in any other game today, and the Brewers facing Tyler Matzek have basically been priced past the point of value, unless you can save some ducats elsewhere. The Rockies are at home, and Kyle Lohse is great but gives up an above-average rate of fly balls.
Corey Dickerson – $7,719
Brandon Barnes – $4,192
Josh Rutledge – $4,701
Your pick of Justin Morneau ($8,236) or Troy Tulowitzki ($9,897) to anchor the stack, depending on how your budget and positions look.
