Identifying significant SP skill splits and using them to your advantage can be a helpful strategy to get the most out of your starting rotation down the stretch.
In addition, this kind of analysis can help you find hidden skills before they blossom, which can be a big help for those already looking ahead to 2017.
Here, let's take a look at the SP with the widest lefty-righty BPV splits so far in 2016.
First, the SP who own the best skills against RH bats:

AMERICAN LEAGUE
Chris Devenski (RHP, HOU) is someone worth keeping an eye on if you play in a deep league. While he hasn't started a game for HOU since May, his skills in the second half suggest he could stick as a SP once he gets another shot: 21/3 K/BB in 20 IP. Behind that flash of elite command is a strong 14% SwK% and 67% FpK%. He also has posted very nice aggregate skills against LH bats: 8.9 Dom, 2.4 Ctl, 33% GB%, 107 BPV.
Tyler Duffey (RHP, MIN) still carries surface stats that would damage any fantasy rotation (5.93 ERA, 1.49 WHIP). That said, he has looked excellent in a tiny two-start sample so far in August: 14/1 K/BB in 12 IP with a 13% SwK% and 72% FpK%. Digging deeper, Duffey has been able to handcuff lefty bats (137 BPV) but hasn't fared that well against righties (68 BPV). A tweak there could help him stick as a mid-rotation guy.
Danny Duffy (LHP, KC) has emerged as an upper-tier SP since re-entering the KC rotation in May, and he hasn't done so by feasting only on LH bats. His skills have been excellent against RHers too: 9.8 Dom, 2.0 Ctl, 31% GB%, 131 BPV. Adding a groundball pitch to his repertoire is the last piece he needs to stick as an impact SP.
Kevin Gausman (RHP, BAL) has posted a 110+ BPV against both LH and RH bats so far in 2016. And his surface stats against lefties have been ace-like (2.75 ERA, 1.11 WHIP). Those marks have eroded a lot against RHers (5.19 ERA, 1.48 WHIP), but that has been due to an inflated 26% hr/f more than anything else. As that mark comes down, so too will his ERA.
Félix Hernández (RHP, SEA) used to be a sure-fire rotation anchor worth starting every time he took the ball. This season, not so much. His skills have been terrible against LHers: 6.7 Dom, 4.8 Ctl, 53% GB%, 20 BPV. The only reason he has a 3.02 ERA against them has been due to a friendly 82% S%, which we can't bank on continuing. And his prior dominance against righties is on shaky footing too, as his skills against them are more good than great (99 BPV). The window to sell high on Hernandez in keeper leagues is closing quickly.
Lance McCullers (RHP, HOU) quietly has put up the best skills against LH bats by anyone not named Kershaw: 14.6 Dom, 4.2 Ctl, 59% GB%, 184 BPV. He owns a bad 1.54 WHIP against them due to a crazy 46% H%. With a tweak against same-sided bats (47 BPV), McCullers would gain the consistency needed for him to become an upper-tier SP.
James Paxton (LHP, SEA) is another blossoming SP whose LH/RH splits indicate that he has the goods for long-term success. His skills against opposite-sided batters have been near-elite: 8.7 Dom, 1.5 Ctl, 48% GB%, 142 BPV. He'll enter 2017 as a premium breakout target.
NATIONAL LEAGUE
Tyler Anderson (LHP, COL) quietly owns a near-3.00 ERA that most owners won't be aware of. And it's a mark that comes with nearly full skill support (115 BPV, 3.46 xERA). In addition, the lefty Anderson has been pretty lethal against RH bats: 7.9 Dom, 1.1 Ctl, 57% GB%, 146 BPV. As a GB pitcher who can miss bats, Anderson remains a good end-rotation option in deep leagues.
Archie Bradley (RHP, ARI) has posted bad stats after 16 starts with ARI (4.80 ERA, 1.51 WHIP). A closer look shows that those are the direct result of terrible stats and skills against lefties: 5.06 ERA, 2.06 WHIP, -2 BPV. His upside starts to come out against RH bats: 9.2 Dom, 3.3 Ctl, 43% GB%, 100 BPV.
Iván Nova (RHP, PIT) has a chance to provide some nice value down the stretch. His skills against RHers in 2016 have been very good (116 BPV). He has a 5+ ERA against them solely due to a 25% hr/f, a mark that was likely inflated due to Yankee Stadium.
David Phelps (RHP, MIA) is transitioning to a starting role in the MIA rotation, and before you dismiss his ability to stick there, note that his skills against RHers have been better than any pitcher in MLB not named Fernandez or Scherzer: 52/7 K/BB in 36 IP. That elite command has produced a 205 BPV. His struggles come against lefties, against whom he has a poor 1.4 Cmd. So, you'll want to sit him against strong lefty lineups, but he makes for a high-upside play against RH-leaning lineups.
Robbie Ray (LHP, ARI) is one of a select number of SP who can claim a 100+ BPV against both LH and RH bats. He has been untouchable against lefties (178 BPV), but he also has been very good against RHers: 10.9 Dom, 3.7 Ctl, 43% GB%, 116 BPV. If he can keep his walks under control, Ray will continue to make for an excellent speculation.
Joe Ross (RHP, WAS) is a step away from starting to fulfill the skill upside that comes out when he faces RH bats (138 BPV). His command erodes him when he faces southpaws: 6.9 Dom, 4.1 Ctl, 39% GB%, 30 BPV. A tweak there would help him show sustained growth. At age 23, he's got time, as long as his shoulder is sound.
Dan Straily (RHP, CIN) has struggled against lefties for years, a weakness that has prevented him from sticking as a viable mid-rotation SP until this season. Problem is, that problem has continued during his mini-breakout this year: 6.0 Dom, 5.1 Ctl, 33% GB%, -18 BPV. His stats (2.91 ERA, 0.99 WHIP) and skills (105 BPV) show life when he faces RH bats, but they aren't good enough to make up for his significant struggles against lefties.
Julio Teheran (RHP, ATL) has completely handcuffed RH bats so far in 2016: 9.7 Dom, 0.9 Ctl, 45% GB%, 173 BPV. On the flip side, his skills vs. LH haven't even been roster-worthy: 6.0 Dom, 3.2 Ctl, 35% GB%, 34 BPV. The only reason he has a 3.19 ERA and 1.10 WHIP against them has been due to a friendly 22% H%. Keep that significant split in mind once he returns from the disabled list and faces lineups with impact lefty bats.
