Welcome to DraftKings fantasy baseball, the Official Daily Fantasy Game of Major League Baseball.
The players listed below could provide difference-making stats for DraftKings participants on Tuesday.
Matt Duffy (Giants): Hitting .303, the third baseman has been a cost-effective option in many 2015 DraftKings contests. Duffy could fare well when he vacates his pitcher-friendly home park and puts his lifetime .794 OPS against right-handers (.687 vs. lefties) on the line against righty Chase Anderson (career 4.15 ERA, 1.34 WHIP) at offense-inducing Chase Field.
Brian McCann (Yankees): The catcher will be poised to provide production from a premium position when he puts his lifetime .830 OPS against right-handers (.758 vs. lefties) to the test at his hitter-friendly home park against Orioles righty Kevin Gausman (career 4.33 ERA, 1.30 WHIP).
Evan Longoria (Rays): The third baseman has long fared best vs. left-handers, against whom he has produced a career .922 OPS (.802 vs. righties). Longoria will be poised to drive in multiple runs when he faces rookie southpaw Matt Boyd (8.36 ERA, 1.83 WHIP) and a Tigers bullpen that ranks 29th in baseball with a 4.73 ERA.
Logan Forsythe (Rays): Hitting .290 with 15 homers and nine steals across 535 plate appearances, Forsythe is coming down the stretch of a breakout season. The second baseman may improve on his lifetime .830 OPS against left-handers (.635 vs. righties) when he works against the inexperienced Boyd (6.93 FIP).
Brandon Guyer (Rays): From a likely perch atop the lineup, the outfielder will be in position to score multiple runs when he puts his lifetime .782 OPS against left-handers (.669 vs. righties) on the line against Boyd and a suspect Tigers relief corps.
Josh Donaldson (Blue Jays): With a lifetime .300/.381/.610 slash line against left-handers, Donaldson has proven to be among the best in baseball in those matchups. The third baseman -- who has compiled 36 homers, 114 RBIs and 105 runs scored across 600 plate appearances this season -- could produce a game-changing total in DraftKings contests when he faces Red Sox rookie southpaw Henry Owens (5.87 ERA, 1.50 WHIP).
Troy Tulowitzki (Blue Jays): The shortstop may be poised to provide production at a premium position when he brings his lifetime .962 OPS against left-handers (.850 vs. righties) into a matchup with the inexperienced Owens. Tulowitzki may also thrive late in the game against a Red Sox relief corps that sits 24th in the Majors with a 4.25 ERA.
Kevin Pillar (Blue Jays): Pillar may be in position to improve on his career .699 OPS against left-handers (.656 vs. righties) when he meets up with Owens (5.05 FIP). The outfielder may be part of a productive lineup, as the Blue Jays lead the Majors with an .832 OPS against southpaws. Also of note: Pillar and his teammates will attempt to put balls into play against a Red Sox defense that sits 26th in baseball with a .677 defensive efficiency ratio.
Ryan Braun (Brewers): With a lifetime .337/.404/.634 slash line against left-handers, Braun has proven to wield a potent bat in those matchups. The outfielder -- who has compiled 25 homers and 22 steals across 521 plate appearances this season -- has the skills to produce in multiple ways when he faces Marlins rookie southpaw Adam Conley (5.02 ERA, 1.43 WHIP).
Jonathan Lucroy (Brewers): As a big leaguer, the catcher has produced an .843 OPS against left-handers that exceeds his .746 mark vs. righties. Lucroy could provide production at a premium position when he faces the inexperienced Conley (4.50 FIP).
David Ortiz (Red Sox): With 31 homers and 86 RBIs across 455 at-bats this season, the slugger remains one of the most effective power hitters in baseball. Ortiz could rip a round-tripper when he brings his lofty lifetime .975 OPS against right-handers (.810 vs. lefties) into a matchup with Blue Jays righty R.A. Dickey, who has produced a 1.2 HR/9 rate since the outset of the 2013 season.
Taylor Jungmann (Brewers): With a 2.42 ERA and a 1.15 WHIP across his initial 16 starts, the rookie righty has already become a trusted option in DraftKings contests. Jungmann will be poised to extend his impressive debut when he works at pitcher-friendly Marlins Park against a Miami lineup that ranks last in the Majors with a .669 OPS against righties.
Aaron Nola (Phillies): The rookie right-hander will be poised to thrive when he brings his 4.02 ERA and a 1.16 WHIP into a matchup with a Braves lineup that ranks 29th in the Majors with a .679 OPS against righties and last in baseball with 83 homers.
Edinson Volquez (Royals): The right-hander will bring a 3.53 ERA into a matchup at his pitcher-friendly home park against a Twins lineup that ranks 25th in baseball with a .693 OPS vs. righties. Volquez may benefit from working in front of a Royals squad that sits third in baseball with a .706 defensive efficiency ratio. And once he leaves the game, his quest for a win could be aided by a Kansas City bullpen that leads the Majors with a 2.44 ERA.
Sonny Gray (A's): With a 2.36 ERA and a 1.00 WHIP, the right-hander has been among the most dominant starters in baseball this season. Gray could combine several strikeouts and quality frames when he works at his pitcher-friendly home park against an Astros lineup that sits second in the Majors with 1,205 whiffs.
Michael Wacha (Cardinals): With a 15-4 record, a 2.69 ERA and a 1.13 WHIP, the right-hander has emerged this season as the staff ace on the winningest club in baseball. Wacha could thrive when he works at his pitcher-friendly home park against a Cubs lineup that leads the Majors with 1,258 strikeouts.
All statistics are accurate through the completion of Sunday's games.
