Reminder: Always double check the lineup card before rosters lock to make sure that a player you've chosen to roster is playing that day, and check the weather to make sure your players won't get rained out of their game.
First tier: Corey Kluber vs. Seattle Mariners, $11,100
Kluber is my favorite choice for P tomorrow. This is where the Mariners rank vs RHP:
K%: 23.6%, 3rd highest
wRC+: 89, 22nd
ISO: .146, 14th
Kluber ranks 3rd in FIP at 2.23 and 4th in K% at 30.6% on the year and recently got Yan Gomes back behind the plate. Since his slow April start (which was a theme last year during his Cy Young campaign, too), Kluber has gone on a rampage, posting a 2.01 FIP and 34.2% K% in 7 starts since May began.
Second tier: for a salary relief option, one guy who might be overlooked is Masahiro Tanaka ($9,400) vs the Washington Nationals. Tanaka looked like vintage Tanaka last time out, averaging 93 mph on his fastball while topping out at 96 mph (on his last pitch of the outing, too). His fastball averaged 2 mph more than his average fastball velo during any start earlier this year, which made his splitter even nastier. His fastball also had movement. Here's some looks:
Unfortunately, the cold water is that matchup isn't so great because he faces Scherzer and a Nationals offense in Yankee Stadium that just got Anthony Rendon back. But if you want a guy to take in a tournament who might be undervalued and provide salary relief to load up on higher ceiling hitters, I think Tanaka can be that guy. Rookie sensation Eduardo Rodriguez ($8,200) vs a bottom third Orioles offense vs LHP (93 wRC+, 21st) is another good option.
SS- Jhonny Peralta vs. Jorge de la Rosa in Coors Field, $4,200
Peralta's numbers vs LHP are elite. In 332 PA since the start of 2013, Peralta has a 149 wRC+ and .220 ISO, far and away the best among qualified SS. de la Rosa has a career 4.64 FIP vs RHB with it at 4.36 since 2013.
3B- Pablo Sandoval vs. Miguel Gonzalez, $2,200
Sandoval might be the best punt play available against RHP. He's hitting them to a 135 wRC+ this year, but his awful play against lefties is the driving force behind his price drop. He faces Miguel Gonzalez, who has a below average 4.15 FIP vs LHB in 258 career IP since 2012.
1B- David Ortiz vs. Miguel Gonzalez, $2,500
Ortiz mirrors Sandoval very closely: his price has tanked because of bad performance against LHP, but he's hitting RHP very well. Ortiz has a 137 wRC+ and .218 ISO vs RHP this year.
OF- Giancarlo Stanton vs. Mark Buehrle, $4,700
Since the start of last year, Stanton has been Ruthian vs LHP, posting a 191 wRC+ with a .342 ISO in 172 PA. The matchup takes place in Rogers Centre, a huge park upgrade for him.
