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.
1B- Lucas Duda vs. Carlos Martinez, $3,100
In 588 PA vs RHP since the start of last year, Duda has a 150 wRC+ (5th best among 1B), .247 ISO (5th best) and 29 HR (6th best). He faces Carlos Martinez, who has gigantic platoon splits vs LHB. Martinez has a 5.51 FIP and .866 OPS against vs LHB in 56 IP vs them since the start of last year, and the most recent sample is even worse: Martinez' 6.56 FIP vs LHB this year is 6th worst in baseball, and left handed opponents have ended 21.4% of their at bats vs Martinez with a hard hit ball, 9th worst in baseball.
Duda's power is down, but he is still hitting the ball just as hard as he was last year (21.4% hard hit% in 2015, 21.8% in 2014). It's probably small sample size noise rather than anything to be worried about, and his price drop because of that provides value to be gained.
OF- Adam Jones vs. Roenis Elias, $3,500
In 191 PA dating back to the start of 2014, Jones has a 191 wRC+ vs LHP, third best among outfielders (only Nelson Cruz and Jose Bautista have a higher wRC+). His .279 ISO and 11 HR are fourth best, and he faces a LHP with a below average 4.34 FIP in 146 career IP from 2014-15. Jones is priced at $3,500, 21st among OF, but you can expect production much, much better than that. He's a great value play.
OF- Carlos Gonzalez vs. Severino Gonzalez, $3,200
CarGo's outcomes have been brutal so far with a 54 wRC+, but I still believe in his talent despite what 6 weeks have produced. Gonzalez has the 9th highest average exit velocity in baseball at about 94 mph off the bat, so he's still generating plenty of force behind his swing. He faces RHP Severino Gonzalez, who has a 4.52 FIP in 187 minor league IP spread out between AA and AAA since the start of last season. An outfielder with CarGo's talent, in Coors Field, against that pitcher, priced at this level, just screams value.
P- Tyson Ross vs. Chicago Cubs, $8,900
In 241 IP since the start of 2014, Ross owns a 3.28 FIP, 58% GB% and 24.5% K%. The matchup takes place at home in PetCo, the best pitcher park in baseball, and he faces a Cubs team that has the 2nd highest K% vs RHP at 25.4%. The Cubs also have a bottom third wRC+ vs RHP at just 91 and middle of the pack ISO at .139. Ross has allowed the 15th lowest HR/9 since the start of last year at 0.60, and with PetCo's park effects aiding him, the Cubs power bats will have a difficult time hitting the ball over the fence. Ross is my favorite pitcher for today's slate.
(priced) Punt play: Rickie Weeks vs. Wei Yin Chen, $2,200
Weeks is priced at the FD minimum but there are reasons to expect a strong shot at production. In 183 PA vs LHP since the start of last year, Weeks has a 148 wRC+, 24th best in baseball, he'll be getting a big park upgrade in Camden Yards. Chen has a below average 4.21 FIP vs RHB in 174 IP since the start of 2014, right about where his career mark of 4.30 is. Weeks is priced as a punt play but will likely turn in high level production, giving a fantasy owner a ton of value.
