It’s the dog days of summer, and we’ve got a full 15-game slate on Tuesday. It’s an all-evening affair beginning at 6:35 pm ET when the Yankees and Orioles continue an AL East series in Charm City. The schedule gives plenty of opportunities to find the best MLB bets today, including the top pitcher props.

After looking over the slate, we’ve identified our favorite plays to bolster your bankroll. Without further ado, let’s get to the best options on the board for Tuesday, August 18.

Best MLB Pitcher Strikeout Bets Today: Player Props for August 18

Zack Wheeler, Phillies Over 6.5 Strikeouts (-155, Hard Rock)

Wheeler is solid as the front-end of the rotation for the Phillies, along with Christopher Sánchez. He seems fully recovered after surgery for thoracic outlet syndrome and is 10-4 with a 2.89 ERA, a 0.997 WHIP, and 137 strikeouts over 115.1 innings of work. In addition, Wheeler has at least six strikeouts in 13 of his 20 starts, along with three others with five.

Current Miami hitters own a collective .220 average in 59 at-bats against him. Meanwhile, Wheeler holds a 37.3% strikeout rate (22 punchouts) in those at-bats. That includes 23 punchouts over 15 innings of work in three starts against Miami this year. He picks up his share of whiffs again here.

Kyle Harrison, Brewers Over 5.5 Strikeouts (-150, Fanatics)

Harrison turned out to be a solid starter on the bump for the Brewers, adding another successful reclamation project. He is 9-3 with a 3.47 ERA, a 1.125 WHIP, and 114 strikeouts over 93.1 innings in 19 starts. Harrison struggled a bit with distance of late, going five innings or less in his last five starts. Those outings were separated by a month-long stint on the injured list. Despite the short outings, Harrison still delivers strikeouts, recording at least six whiffs in 10 of his starts.

Seattle is a below-average team in terms of striking out at the plate. Meanwhile, Harrison is 6-1 with a 1.38 ERA and 70 strikeouts over 52 innings at home this year. He gets the job done and cashes this prop.

Best MLB Pitcher Prop Picks for Aug. 18:

Ranger Suarez, Red Sox Under 15.5 Outs (-155, Fanatics)

Suarez was expected to be a big difference-maker for the Red Sox’ rotation this season. Instead, he is 4-3 with a 3.25 ERA and a 1.185 WHIP over 108 innings in 21 starts this season. In addition, his numbers have tailed off precipitously of late. Suarez hasn’t gone deeper than five frames in any of his last five starts, with a stay on the IL in the middle. Meanwhile, he’s gone less than six frames in 13 of his 21 starts this year. In his career, Suarez struggled against Arizona.

Current Diamondback hitters own a robust .404 average (42 of 104) with nine doubles and three homers. His struggles continue here, and that knocks him out earlier than anticipated.

Jackson Kent, Nationals Under 12.5 Outs (-105, Hard Rock)

Kent made his major league debut in his last outing, facing the Cubs at Nationals Park. While he started strong, his control issues caught up with him. Kent threw four strong innings to start before coming unraveled in the fifth. He surrendered a single, a walk, and an RBI double before getting the hook. Kent threw 78 pitches, but just 37 were strikes. Kent finished with four innings pitched as he allowed three runs on three hits with five walks and six strikeouts in an eventual 12-6 Nationals loss. While some of that may be nerves, the fact remains that until we see him turn in a better outing, you have to think that he's going to have a quick hook.
