Premier MLB Prop for Saturday
Jack Flaherty Over 4.5 Total Strikeouts
Chris Sale is anticipated to rejoin Atlanta’s pitching rotation on Saturday, with his Over 6.5 line appearing this morning. This often signifies a confirmed start. While we observe a slight betting advantage on Over at -125 via Hard Rock, we’re hesitant to back a 38-year-old pitcher returning after 2.5 months sidelined due to an injury.
Indeed, none of the foremost four projected strikeout pitchers feature a line below 6.5, necessitating a look towards Detroit’s Jack Flaherty to pinpoint a captivating Over. FanDuel currently offers Over 4.5Ks at -122 this morning. Flaherty’s line is set conservatively because his recent performance against Kansas City, during his last start on August 24, was subpar, resulting in eight earned runs conceded over five innings with only three strikeouts. Despite averaging 1.3 fewer strikeouts in away games compared to home games, Flaherty still maintains a respectable 5.6 punchouts on the road, holding a solid 7-4 Over 4.5 record. Prior to his last disappointing showing, Flaherty delivered seven scoreless innings, racking up nine strikeouts against Houston. The hope is that we witness that version of Flaherty tonight.
