With 15 MLB games in action, there are plenty of player props to choose from. Let's go through the best ones to add to your bet slips this Wednesday, September 14.MLB Player Prop #1: Gunnar Henderson Over 0.5 Singles (+125)Washington Nationals vs. Baltimore Orioles Match DetailsFixture: Baltimore Orioles @ Washington NationalsDate & Time: Wednesday, September 14, 7:05 p.m. EDTVenue: Nationals Park, Washington, D.C.Gunnar Henderson, the No. 2 prospect in all of baseball, has burst onto the scene in Baltimore. He made his debut about two weeks ago, and so far, he's hitting .304 in 46 at-bats. Henderson has been a base hit machine, and lately, he's picked up a single in six of his past seven starts. Opposing Nationals' starter Patrick Corbin is a lefty, but he's had an awful season. His 6.30 ERA and 1.71 WHIP make him one of the worst starters this year, so expect the Orioles' Henderson to notch a base knock tonight.Locked On Orioles@LockedOnOriolesGunnar Henderson through his first 50 MLB plate appearances:.304/.360/.457, 135 wRC+, 1 HR, 11 K, 4 BB39435Gunnar Henderson through his first 50 MLB plate appearances:.304/.360/.457, 135 wRC+, 1 HR, 11 K, 4 BB https://t.co/34aHewnDHV"Gunnar Henderson through his first 50 MLB plate appearances: .304/.360/.457, 135 wRC+, 1 HR, 11 K, 4 BB" - Locked On OriolesMLB Player Prop #2: Drew Rasmussen Over 15.5 Outs Recorded (-125)Toronto Blue Jays vs. Tampa Bay Rays Match DetailsFixture: Tampa Bay Rays @ Toronto Blue JaysDate & Time: Wednesday, September 14, 7:07 p.m. EDTVenue: Rogers Centre, Toronto, OntarioDrew Rasmussen has been amazing since the All-Star break, carrying a 5-1 record, 1.62 ERA, and 0.88 WHIP. He'll be up against a solid Blue Jays lineup, but lately, Rasmussen has been able to shut down lineups. Facing Toronto in three starts this year, he's allowed one earned run each game, which is excellent. On the season, the Rays' righty has averaged just over five innings per start, but in his last five starts, he's gone pretty deep. In all five of these starts, he's recorded 16 or more outs, so expect him to do so again tonight.Rob Friedman@PitchingNinjaDrew Rasmussen, Nasty 90mph Cutter. 8th K thru 5.18111Drew Rasmussen, Nasty 90mph Cutter. ✂️8th K thru 5. https://t.co/ecf75rb2mz"Drew Rasmussen, Nasty 90mph Cutter." - Rob FriedmanMLB Player Prop #3: David Peterson To Record A Win (+165)New York Mets vs. Chicago Cubs Match DetailsFixture: Chicago Cubs @ New York MetsDate & Time: Wednesday, September 14, 7:10 p.m. EDTVenue: Citi Field, Flushing, New YorkDavid Peterson has a had a solid year for the Mets so far, sporting an 8-4 record and 3.56 ERA. Tonight, he'll be taking on a Cubs lineup that has just a .292 OBP against lefties. Even though Peterson has been hit around a bit in his last couple of starts, the Cubs' lineup is very manageable. Look for him to pick up his ninth victory as the Mets are eight games over .500 versus lefties like Drew Smyly, the Cubs' starter.
