DraftKings, FanDuel Pitchers - MLB DFS Lineup Picks
It's a loaded pitching slate, so there are certainly more than just these five arms as viable options, but here are some of my favorites.
Sonny Gray - STL at TEX ($8K DK; $9.5K FD)
The Texas Rangers offense has just fallen apart this month. They are the worst team in MLB across the last two weeks regarding wRC+ at 67 against RHP. They have a poor team ISO of .115, which means they have very little power against righties. Sonny Gray has had a couple of solid outings recently, going 6+ innings in three of his last four starts while allowing only three runs in that time.
The Phillies blew him up for seven runs, but with the recent play of the Rangers, I don't see Gray having that issue with them. Gray has a solid 26% K% this season to go with a low 5.1% BB%.
Kodai Senga - NYM vs. COL ($8.9K DK; $10.2K FD)
Kodai Senga has flown under the radar a bit this season. He has been great at avoiding giving up runs; his biggest downfall, however, has been the walks. If he can keep those low, Senga should have no issue going far into this game and picking up the win, which he has done five times this season. He has an impressive 1.46 ERA on the season and has only given up two runs at home this season.
They are getting the struggling Rockies as well, who have a wRC+ of 77 across the last two weeks of RHP. The Rockies also have a 28% strikeout rate. This is a home run spot for Senga as long as he keeps the walks low. He should cruise through Colorado.
Robbie Ray - SF at MIA ($9K DK; $10.6K FD)
Robbie Ray has been dynamite this season. He is one of the best LHP in the league this season, only behind a couple of big names in Max Fried and Tarik Skubal. Ray's last six starts are what I want to focus on, as he has 7+ strikeouts in all but one of those games and has a quality start in all six games!

The Marlins were only able to muster up three hits in last night's game against the Giants, and their hitting against LHP has them below average in most metrics across the last few weeks. I see a lot of people going toward Senga as their cash game pitcher, but I think Ray could be one of the best options on the slate.
Also Consider: Michael Wacha - KC vs. DET ($6.8K DK; $8.4K FD), Kyle Hendricks - LAA at CLE ($7.4K DK; $6.9K FD)

DraftKings, FanDuel Infielders - MLB DFS Lineup Picks
Ryan O'Hearn, 1B/OF - BAL vs. Davis Martin ($4.4K DK; $3K FD)
I'm surprised to see him as cheap as he is. Ryan O'Hearn is red-hot right now; he has 17 hits in his last eight games, with two of those being home runs. He also gets to go against a RHP, and although Davis Martin has been solid against LHH this season, O'Hearn has a .472 wOBA and .649 SLG against RHP so far this season.
Ryan O’Hearn is on an absolute HEATER right now for the Orioles. He launched this one for his 9th 💣 of the season

— Baseball Unstitched Podcast (@BaseUnstitched) May 28, 2025
He has been one of the best hitters for this poor Orioles team, but makes for an elite one-off or part of a small stack.
Brett Baty, 3B/2B - NYM vs. Antonio Senzatela ($3.1K DK; $2.7K FD)
Brett Baty has been great against RHP and extremely good at home this season. This is a recipe for a big game for him. Senzatela has been terrible this season with an over 6.50 ERA, and he has been crushed by LHH this season.
Senzatela has a .421 wOBA against LHHs and 46.3% hard-hit%. This is a great spot for Baty, who is relatively cheap compared to his bigger-name counterparts such as Francisco Lindor and Pete Alonso.
Danny Jansen, C - TB vs. Colton Gordon ($2.5K DK; $2.5K FD)
The people who make the prices don't know about Jansen vs. LHP this season. He has been incredibly efficient against them as he has a .415 wOBA and a wRC+ of 178 this season. He also has an absurd 26% BB% against lefties. Gordon hasn't been anything special this season for the Astros, and I don't expect that to change anytime soon. Jansen is dirt cheap and is a perfect Rays stack option.
Also Consider: Francisco Lindor - SS ($5.6K DK; $4K FD), Junior Caminero - 3B ($4.3K DK; $3.1K FD), Ivan Herrera - C ($5.4K DK; $3.1K FD)
DraftKings, FanDuel Outfielders - MLB DFS Lineup Picks
Brendan Donovan, 3B/SS (FD) 2B/OF - STL vs. Patrick Corbin ($5K DK; $3.1K FD)
Patrick Corbin came back down to earth after a decent start to the season. He has three straight games of three runs allowed, and STL has been hitting the ball much better. The super-utility in Brendan Donovan has been specifically hitting the ball extremely well. He has nine hits in the last five games.
Corbin has given up a .375 wOBA and .537 SLG against LHH. Donovan has a .304 wOBA and .412 SLG against LHP, which is the third best on the team.
Brandon Nimmo, OF - NYM vs. Antonio Senzatela ($3.8K DK; $2.8K FD)
A lot of people will gravitate toward Juan Soto for the same reason you should go to Nimmo for cheaper. Soto brings more power but has been much worse recently. Nimmo has as many hits in four games as Soto has in his last 10 games. LHH has done extremely well against Senztaela, as I mentioned earlier with Baty. Nimmo makes for an elite pairing alongside Baty in your Mets stacks!
Brandon Nimmo has been THRIVING in his move to the 2 hole this season, slashing an EXCELLENT 👀

— Fireside Mets (@firesidemets) May 30, 2025
Michael Harris II, OF - ATL vs. Walker Buehler ($3.6K DK; $2.5K FD)
Michael Harris II isn't quite having the season he would like to have, but he does have nine hits in as many games. Walker Buehler has been great against RHH, but not great against LHH. This makes Harris an interesting option, especially at his price. LHH has a .361 wOBA and .424 SLG against Buehler this season.
Harris hasn't quite had the power, but he has been able to get on base, and just like in "Moneyball," that's what matters most!
Also Consider: Jarren Duran - OF ($5.2K DK; $3.7K FD), Kyle Schwarber - OF ($5.7K DK; $4.2K FD), Josh Lowe - OF ($5K DK; $3.3K FD)
DraftKings, FanDuel MLB DFS Stacks
New York Mets (5.5 implied run total) vs. Antonio Senzatela (COL)
The Mets have been a bit lackluster against RHP across the last two weeks, but this is the perfect bounce-back spot for them. Senzatela has been awful this season, and the Mets should have no issue exploiting that at home with one of the best-implied run totals on the slate.
Tampa Bay Rays (4.3 implied run total) vs. Colton Gordon (HOU)
The Rays have been sneaky good against LHP across the last two weeks with a combined wRC+ of 159. The only team better in that span against LHP is the Astros. Gordon hasn't been great in three starts, giving up three runs in all of those games and at least five hits.
Baltimore Orioles (5.3 implied run total) vs. Davis Martin (CHW)
Davis Martin has been serviceable for the White Sox, but if the LHH in the lineup can get to Martin early, they could get him out of there and to the bullpen, which hasn't been great this season.
