Giants vs Guardians MLB Betting Preview
Action PRO projects Giants SP Landen Roupp for 3.66 strikeouts this afternoon against the Guardians, giving us a nice 11.2% edge against the market when compared to his current prop line of over/under 4.5, which is good enough to tag the under with a B grade in our system.
Roupp has had a rough month, with a 5.74 ERA in August.
He has allowed four or more runs in three of his past four starts, pitching fewer than five innings in two of them.
Roupp is also dealing with control issues, with 15 walks in his past four outings combined.
Those problems have cut down his strikeouts and could happen once more against a contact-heavy Cleveland lineup today.
Giants vs Guardians Pick, Betting Analysis
Roupp has gone under this line in two of his past four games and had just five strikeouts in his last one.
Let's fade him this afternoon on his Ks line against the Guardians.
Pick: Landen Roupp Under 4.5 Strikeouts (-140, bet365)
