MLB Pitcher Prop Bets - Today's Betting Picks

Taj Bradley OVER 5.5 strikeouts (-120 DraftKings Sportsbook)

Taj Bradley will square off with the strikeout-happy Twins this afternoon in the day's first game. The Twins have struck out at a 26.2% clip over the last 30 days against right-hand pitching. They lead baseball on the season in the split with a 27.4% K%. Bradley owns a 29.2% K% on the season with an 11.5% SwStr%. In his two starts since he was called up in September, Bradley has gone 86 and 93 pitches, striking out seven and five showcasing his new change-up. He gets his best matchup since his call-up back to the big leagues. I expect him to get six or more strikeouts tonight. 

Logan Allen OVER 5.5 strikeouts (-115 DraftKings SportsBook)

Logan Allen and the Guardians will play a day game in San Francisco against the Giants. The Giants have been one of my favorite teams to target recently against left-hand pitching. Since August 1, they own a 28.3% K% against the split. On the season, Allen has a 22.7% K% with a 10.9% SwStr%. Over his last five starts, he has struck out five or more batters four times. He now has arguably his best matchup with the Giants. 

Jackson Rutledge OVER 3.5 strikeouts (-125 DraftKings SportsBook)

Jackson Rutledge will make his major league debut tonight for the Washington Nationals against the Pittsburgh Pirates. Rutledge is the Nats' number 13 prospect and was a former first-round pick. He has a 3.71 ERA, with 106 Ks in 119 IP in 23 starts in the minor leagues this season. On the season, the Pirates own a 23.8% K% against right-hand pitching. Over the last 30 days, they hold a 22.8% K% against the split. I love getting value on a decent arm at over 3.5 strikeouts in his big league debut in a good matchup. Let's hammer the over.

Bonus Bets: Connor Phillips OVER 5.5 Ks, Eduardo Rodriguez OVER 17.5 Outs, Spencer Strider OVER 8.5 Ks

MLB Hitter Prop Bets - Today's Betting Picks

CJ Abrams OVER 1.5 total bases (+110 DraftKings SportsBook)

CJ Abrams and the Nationals will square off against opener Colin Selby and the Pirates bullpen. Quinn Priester is projected to be the PLR for the Pirates as well. Both of these righties struggle against left-handed bats. Selby, on the season, has a .423 wOBA, .214 ISO, and a 77.8% hard hit against the split, while Priester has a .493 wOBA, .333 ISO, and a 51.8% hard hit. Abrams has been on a tear and, over his last 30 days against righties, owns a 160 wRC+, .410 wOBA, and a .632 SLG. He will have a tremendous matchup for at least three at-bats, giving him a great chance to get his over in total bases.

Ryan Mountcastle OVER 1.5 total bases (-120 DraftKings SportsBook)

Whenever Ryan Mountcastle faces a lefty, we over here at RotoBaller slam his over in total bases. Today is no different. The Orioles will face Drew Rom this evening. Rom has struggled against righties to a .415 wOBA, .194 ISO, and a 53.4% hard hit. Mountcastle has always been tremendous in his career against the split. Since August 1, Mountcastle has owned a 205 wRC+, .467 wOBA, and a .660 SLG.

Bonus Bets: Orlando Arcia OVER 0.5 TBs
