Free MLB Pick

The Red Sox are firing on all cylinders outscoring their opponents by 31-10 in their last four games. The scoring numbers on the defensive side may change today with Corey Kluber on the mound. Kluber has been a disaster in day games, going 0-3 with a 6.92 ERA, and his back numbers against the San Diego roster are mediocre, and he might be exactly what the Padres need to get their offense going. On the mound for the home side is Michael Wacha, who has been ultra-sharp in his last three with a 0.63 WHIP and 0.47 ERA. That said, his historical numbers are extremely poor against the Red Sox lineup, allowing a .321 batting average and .859 slugging percentage in 56 at-bats. I think that to total has some legs today. Take the Over 9.
