This article is part of our FantasyDraft MLB series.
Zack Greinke, ARI vs. PIT ($21,000): Greinke is hard to pass up in this matchup, as he has 27 strikeouts in his last three starts and the other high-end pitcher is going against the Yankees (Dallas Keuchel, $21,300). Greinke hasn't been invincible, allowing an earned run in every start this year, but he's racking up the Ks while walking almost no one (4.5 BB%). He'll face the Pirates, who are bottom of the charts with a .300 wOBA against righties.
Bronson Arroyo, CIN at SF ($10,800): For a cheaper pitcher, it was either Arroyo or Martin Perez ($12,000), but I couldn't pull the trigger on Perez even against the Padres. Arroyo has put in a few decent outings this season and has made it at least five innings in four of his six starts. In his last start, he beat the Giants, giving up five hits and striking out four while allowing two. It wouldn't be crazy to think he could do that again, as San Fran remains last in the majors with a .269 wOBA against righties.
Nolan Arenado, COL vs. LAD ($10,200): Arenado is 6-of-12 in his career against Hyun-Jin Ryu, and that includes the two homers and one double that he had less than a month ago. Ryu is making his return from a DL stint with a bad hip, and he was mostly inconsistent prior to that, already with two losses against the Rockies. He's been slightly better against righties, allowing a .352 wOBA, but that didn't matter against Arenado last meeting and now they're in Colorado.
Jonathan Lucroy, TEX vs. SD ($7,200): Lucroy hasn't had many opportunities against lefties this season (21 at-bats), but he's found his usual success against them with a .384 wOBA. His selling point is that Clayton Richard has struggled against righties, allowing a .418 wOBA, 4.35 xFIP and small 12.2 K%. In fact, 20 of his 22 earned runs have come against righties.
Adam Duvall, CIN at SF ($7,600): It's somewhat surprising that the Giants are putting Ty Blach back on the mound after he was shelled for eight runs in only 3.0 innings in his last start against the Reds. The hope is that Duvall matches his output from that first meeting with another homer. Either way, Duvall has a stout .542 wOBA and .565 ISO against lefties this season. Even if Blach is slightly better, it still probably won't be good enough.
Ezequiel Carrera, TOR vs. SEA ($5,400): Carrera only plays against righties, and this is as good of a matchup as he'll get for a cheap price. He has a mediocre .313 wOBA against righties and isn't striking out too much with a 19.5 K%. There's no telling what Chase De Jong will do, but he has just six strikeouts in his first three starts and only made it 2.2 innings two outings ago. In limited appearances, De Jong is allowing a .438 wOBA and 7.31 xFIP against lefties and that's good enough reason to take a chance on Carrera and any other lefties for Toronto.
Cody Bellinger, LAD at COL ($9,600):Tyler Anderson has fairly equal numbers against both sides of the plate, so there is reasoning to take Bellinger over someone like righty Justin Turner. Bellinger is on a bit of a tear, and while more of his damage comes against righties, he still has a solid .406 wOBA against lefties. Anderson just put in his best start of the season, but 10-strikeout games aren't a trend for him yet.
Seth Smith, BAL at WAS ($7,200): Going against a righty, Smith will be in the lineup where he has mostly thrived this season with a .408 wOBA and .237 ISO. A.J. Cole made his first start last week, and while he wasn't terrible, he wasn't that great, going six innings, giving up four walks and striking out only two.
Eugenio Suarez, CIN at SF ($7,600): Building off what could be another bad start from Blach, Suarez is in a good spot with a solid .457 wOBA and .300 ISO against lefties. Blach may not give up 10 runs this outing, but he's still not a big strikeout guy (6.3 K% versus righties) so Suarez's 26.1 K% shouldn't be a factor. Billy Hamilton ($8,000) also deserves a look if you're banking on Blach struggling again.
Wil Myers, SD at TEX ($9,300): Myers has been the only consistent batter for the Padres this season and this is another solid matchup, even if his numbers against lefties don't say so. On the mound, Martin Perez has a 5.30 xFIP and 13.0 K% against righties, which will help Myers and his 28.9 K%.
