Nationals vs Orioles MLB Betting Preview, Pick
Foster Griffin has been a terrific pickup for the Nationals with a 17.7 K-BB% and estimators averaging a bit below four.
He’s also coming off his best start of the season with a season high 7.1 innings pitched against the Phillies, tying a season high with nine strikeouts.
His number on FanDuel (the only site currently offering a K prop) is set at 6.5 with a generous +132 to the over, which may be reasonable considering he’s only beaten that number in five of 16 starts and not since May 14th before his last time out.
What Griffin has done is post a swinging strike rate above 11% in four of his last five starts, which suggests a strikeout rate closer to a quarter of batters faced, especially considering his above average 18.2 CStr% on the season.
Averaging 23 batters faced per start, though at least 24 in each of his last three starts, we would need Griffin to post a strikeout rate close to 30% to reach this number on Saturday, but there’s reason to think he may be able to pull that off.
To start with, Fangraphs, Rotowire and BARTOLO each project lineups including three LHBs (Gunnar Henderson, Samuel Basallo and Jackson Holliday), which means we’d expect him to see seven to eight LHBs in total and he’s already up near 30% against them (29.2% to be exact).
With Henderson’s 23 K% against LHP, Basallo’s 38.6% and Holliday’s 50%, there’s reason to suggest he may be even better.
While Griffin drops to 21% against RHBs, only one projected Oriole (Taylor Ward) strikes out less than that against LHP this year, which means we can boost that number a bit too.
Being in a situation (park, umpire, weather) that should round out to neutral for strikeouts on Saturday, I have Griffin getting there nearly half the time. It may still mean we lose a bit more often than we win, but the price certainly justifies it.
Pick: F.Griffin over 6.5 Strikeouts +130, 0.5u (Bet to +115)
