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 Monday.
Matt Wieters: As a big leaguer, Wieters has posted an .806 OPS against left-handers that exceeds his .719 mark vs. righties. The catcher could provide production from a premium position when he faces Royals southpaw Danny Duffy, who in his career has allowed right-handed batters such as Wieters to post a .764 OPS (.581 OPS allowed to lefty batters).
:: Fred Zinkie's Daily Picks ::
Mark Trumbo: With 18 homers across 213 at-bats, the outfielder has been one of the most powerful players this season. Trumbo could put a ball into the outfield seats at his hitter-friendly home park when he brings his lifetime .823 OPS against left-handers (.753 vs. righties) into a matchup with the left-handed Duffy (career 4.12 FIP, 1.34 WHIP).

Carlos Gonzalez: In his career, the outfielder has posted an impressive .304/.368/.564 slash line against right-handers. Gonzalez could record a notable total in DraftKings contests when he tangles with Dodgers righty Mike Bolsinger (career 4.23 ERA, 1.41 WHIP) from the heart of a Rockies lineup that ranks fourth in the Majors with a .794 OPS against righties.
Francisco Lindor: The second-year shortstop has posted an impressive career .341/.385/.522 slash line against left-handers. Hitting out of a premium lineup spot, Lindor could have a great game when he faces Mariners southpaw James Paxton, who allowed three earned runs (eight total) across 3 2/3 innings in his only big league start this season.
Nomar Mazara: The rookie outfielder will be in position to improve on his impressive .320/.379/.566 slash line against right-handers when he bats at his offense-inducing home park against Astros righty Mike Fiers, who has logged a 4.84 ERA and a 1.32 WHIP this season.
Dexter Fowler: Hitting atop a talented Cubs lineup, the outfielder could reach base and cross home plate multiple times when he takes his lifetime .833 OPS against left-handers (.773 vs. righties) into a matchup with Phillies southpaw Adam Morgan (7.07 ERA, 1.51 WHIP in 2016).

Ben Zobrist: Hitting .331 with 35 RBIs and 39 runs across 223 plate appearances, the second baseman has been one of the most productive players at his premium position this season. Zobrist could reach base often and drive in multiple runs when he brings his lifetime .829 OPS against left-handers (.776 vs. righties) into a matchup with the left-handed Morgan (career 5.25 ERA, 1.33 WHIP).
Evan Longoria: From the heart of a Rays lineup that ranks third in the Majors with an .810 OPS against lefties, the third baseman could post a notable total in DraftKings contests when he brings his impressive lifetime .295/.378/.543 slash line against left-handers into a matchup with the southpaw Robbie Ray (4.74 ERA, 1.67 WHIP in 2016).

Steve Pearce: With a lifetime .859 OPS against left-handers that exceeds his .716 mark vs. righties, the first baseman -- who is also eligible at second base in DraftKings contests -- will be in position to excel when he faces the left-handed Ray and an unreliable D-backs relief corps.
Robinson Cano: The second baseman has done substantial damage vs. right-handers during his impressive career, recording a lofty lifetime .317/.365/.527 slash line in those situations. Cano may be worth a major investment in DraftKings contests when he faces Indians righty Trevor Bauer (career 4.47 ERA, 1.38 WHIP).
Kyle Seager: The third baseman has traditionally fared best vs. right-handers, against whom he has a lifetime .811 OPS (.699 vs. lefties). Seager could be part of a Mariners stack -- including Cano, outfielder Seth Smith and first baseman Adam Lind -- against the right-handed Bauer (4.27 ERA, 1.35 WHIP in 2016).
Corey Seager: The shortstop could provide production from a premium position when he takes his lifetime .294/.362/.511 slash line against right-handers into a matchup with righty Tyler Chatwood (career 4.11 ERA, 1.50 WHIP). Seager could also excel late in the game against a Rockies relief corps that ranks 25th in baseball with a 4.32 ERA.
Jon Lester: With a 3.07 ERA and a 1.10 WHIP across 43 starts as a member of the Cubs, the left-hander has quickly become one of the most effective starters in the National League. Lester could spin a gem when he faces a Phillies lineup that ranks 29th in baseball with a .609 OPS against southpaws.
Masahiro Tanaka: With a lifetime 3.09 ERA and 1.02 WHIP, the right-hander has the skills to spin a gem when he faces an Angels lineup that ranks 17th in baseball with 239 runs scored. Tanaka's chances of earning a win may be enhanced by the possibility of turning the ball over to an elite trio of relievers -- Dellin Betances, Andrew Miller and Aroldis Chapman.

J.A. Happ: Across 21 starts since Aug. 14, 2015, the left-hander has posted a 2.29 ERA and a 1.05 WHIP. Happ could continue his recent run of success when he faces a Tigers lineup that ranks 15th in the Majors with a .734 OPS against southpaws.
Williams Perez: The right-hander has shown notable improvements by posting a 3.86 ERA and a 1.17 WHIP this season. Perez could be a serviceable second starter in DraftKings contests when he works at pitcher-friendly Petco Park against a Padres lineup that ranks 29th in the Majors with a .641 OPS against righties. Also working in Perez's favor: San Diego has struck out more times (523) than all but two teams in baseball.
All statistics are accurate through the completion of Saturday's games.
