Boston Red Sox - Payton Tolle

Tampa Bay Rays - Freddy Peralta

Boston Red Sox vs Tampa Bay Rays Game Pick

• Boston Red Sox

Boston is the play in a matchup where Tolle provides a strong starting-pitching case. His 3.02 ERA and 1.07 WHIP are well below Peralta’s 4.67 ERA and 1.34 WHIP, and Tolle has struck out 166 hitters in 143 innings. Tampa Bay owns the better record, has won six straight and has been excellent at Tropicana Field, so Boston faces a difficult assignment. Still, the Red Sox rank third in MLB with a 3.61 team ERA and have enough pitching to keep this close before their offense gets chances against Peralta.

Boston Red Sox vs Tampa Bay Rays Over/Under Pick

• Under

Under is the pick with Boston’s pitching numbers playing a major role. Tolle has allowed just 115 hits across 143 innings with a 1.07 WHIP, and Boston owns a 3.61 team ERA. Tampa Bay’s staff has also been strong, posting a 3.75 ERA, 1.14 WHIP, and .229 opponent average. The Rays have scored 31 runs across their last five games, but three of those contests finished with seven combined runs or fewer. With two quality pitching staffs involved, the under will cash on Saturday.
