Happy Tuesday! Today’s 16-game MLB slate begins with some afternoon baseball at Wrigley Field, with the Brewers and Cubs playing the first half of their doubleheader at 2:20 PM ET. The rest of today’s action is slated for a 6:40 PM ET first pitch or later, giving the betting community plenty of entertainment opportunities for after work as well.
As always, be sure to monitor our MLB starting lineups page throughout the day, as unexpected changes in the batting order can result in value opportunities in the betting and DFS markets.
Another reminder – it’s not a bad beat, or unlucky, if you bet a player to hit a home run and his fly ball dies on the warning track because it’s 40 degrees with the wind blowing in! Before locking in any bets, use our MLB weather page, curated by Chief Meteorologist, Kevin Roth. There are countless edges to be found if we make the right reads on possible rain delays and great hitting weather, just to name a few. Taking a look at the weather report can save us from a bad bet that otherwise looks good on the surface.
Below, you can find my 3 picks for Tuesday, August 19th!

Best MLB Player Props for Tuesday, August 19
Here are my top player prop bets for today, with the first pitch scheduled for 2:20 PM ET on Tuesday, August 19th:
- Seiya Suzuki Over/Under 1.5 Hits + Runs + RBIs
- Cristopher Sanchez Over/Under 17.5 Outs Recorded
- Nick Pivetta Over/Under 18.5 Outs Recorded
Seiya Suzuki UNDER 1.5 Hits + Runs + RBIs (-125, BetMGM)
BETMGMSuzuki has been close to a league-average hitter against RHP this season, with a .241 batting average and 115 wRC+. This afternoon, he has the added difficulty of 10+ mph winds blowing in from left field – not ideal for a hitter with such a high fly-ball rate. Suzuki is hitting only .198 with an 86 wRC+ since the All-Star Break. This is good value on the under in what should be very pitcher-friendly weather conditions at Wrigley Field in the first game of today’s doubleheader between the Brewers and Cubs.
Cristopher Sanchez OVER 17.5 Outs Recorded (-174, FanDuel)
FANDUELThe Mariners have had one of the toughest travel schedules in baseball this past week. Last Thursday, they were forced to sit through an extended rain delay, which led to a very late exit from Baltimore en route to New York for their game the following day. On Sunday, they had to travel from New York to Williamsport for Sunday Night Baseball. Then, they had to travel to Philadelphia for a new series beginning on Monday – all of this without a single off-day.
Tonight, Seattle’s offense will have the added difficulty of facing Cy Young contender Cristopher Sanchez. Sanchez has been one of the league’s most efficient starting pitchers in recent weeks, averaging only 3.32 pitches per batter faced. This evening, he gets to face an aggressive Mariners lineup that ranks only 22nd in wRC+ against LHP during the last 14 days. He should have every opportunity to get through 6 innings.
Nick Pivetta UNDER 18.5 Outs Recorded (-185, BetMGM)
BETMGMPivetta is in the midst of one of the great Houdini acts of 2025 for MLB starting pitchers. During his last 9 starts, Pivetta owns a 1.73 ERA but has benefited significantly from a likely unsustainable .185 BABIP, 80.7% strand rate, and 5.6% HR/FB rate. His good fortune on balls in play is even more remarkable given that he’s allowed a higher average exit velocity, a higher barrel%, and a higher hard-hit% than the league-average pitcher during that time period.
Pivetta has the added challenge this evening of this being a hyper-proximity matchup against a Giants offense that just saw him 6 days ago. During the last month, Pivetta has been slightly less efficient than the league-average hurler, averaging 3.89 pitches per batter faced. San Diego is known to give him a long leash, but they have a rested arm barn behind him, which could lead to a slightly quicker hook than we are used to seeing for him – even if he’s throwing the ball reasonably well.
