Rich Hill, LOS at MIA ($8,800): There aren't many sure bets on the bump Sunday, with no pitcher reaching a five-digit price. I'll take a gamble with Hill, who has allowed two or fewer runs in nine of his 12 starts and has struck out 35 in his last four, spanning 26.0 innings. The Marlins have faired decently against lefties, owning a .323 wOBA, 98 wRC+ and modest 19.9 percent strikeout rate, which may limit Hill's upside, but I like his chances to earn a win against rookie Chris O'Grady, which can help offset that.
Chris Iannetta, ARI at MIA ($2,800): I don't feel great about Iannetta's prospects of starting after Saturday night's start. But assuming he plays, he absolutely merits consideration against a struggling Jaime Garcia, who has allowed at least five earned runs in four straight starts. Iannetta has a team-leading .452 wOBA, 176 wRC+ and 1.089 OPS against opposite-handed pitchers.
Danny Valencia, SEA at CWS ($3,200): Both Jean Segura and Nelson Cruz have better splits against lefties, but both are at least $600 more, suggesting Valencia is the definition of value. He has a .359 wOBA and 129 wRC+ against lefties, while White Sox starter Derek Holland is allowing a .386 wOBA to opposite-handed bats.
Starlin Castro, NYY at BOS ($2,800): Sunday's double-header paired with Castro's recent activation from the disabled list suggest he will likely play just once Sunday. Castro is a cheap option who slots in the middle of a potent lineup, and he's faired better against same-handed pitchers, posting a .363 wOBA and 127 wRC+ as opposed to .333/107 against southpaws, suggesting he can find success against Rick Porcello, who has a 1.52 WHIP against right-handed bats.
Justin Turner, LOS at MIA ($3,800): Turner has absolutely destroyed southpaws, going for a .538 wOBA, 1.320 OPS and 241 wRC+ while striking out only 9.1 percent of the time. In place of the injured Edinson Volquez is Chris O'Grady, who allowed five hits and three earned runs in his first 5.1 innings as a big leaguer.
Xander Bogaerts, BOS vs. NYY (3,300): Bogaerts' lack of power limits his upside, but he still leads regulars with a .353 wOBA against righties while sporting a sound 116 wRC+. The Yankees are short on starters, and will trot out Bryan Mitchell for his first start of the year. He comes in a 5.06 ERA and his absence from the bullpen leaves the team short on arms with Sunday's double-header looming. He either is forced to work deep into the contest regardless of performance, or Bogaerts and company chase him early and face an already taxed bullpen.
Marwin Gonzalez, HOU vs. MIN ($3,600): Gonzalez and the Astros' offense came back to earth a bit Saturday against Ervin Santana, but the entire unit looks poised for a bounce back against Kyle Gibson and his 6.31 ERA. Gibson has allowed lefties to post a .403 wOBA against him, while Gonzalez continues to lead the way among Astros regulars with a .434 wOBA, 178 wRC+ and 1.042 OPS.
Jacoby Ellsbury, NYY at BOS ($2,900): Ellsbury has scored at least 12.4 fantasy points in three of his last four games. His splits aren't encouraging, but he is 12-of-34 (.353) with four homers in his career against Red Sox starter Rick Porcello, who has a 5.34 ERA at Fenway Park, where he's allowing a .341 wOBA to lefties.
Jason Heyward, CHC at BAL ($2,700): Heyward has been hot coming out of the break, garnering multiple hits in both outings, scoring three times with three extra base hits and runs scored. He's been at his best away from home, especially against righties, posting a .392 wOBA and 141 wRC+ in that scenario. That plays far too well against O's starter Ubaldo Jimenez, who has allowed a .459 and 1.110 OPS against lefties at home.
