Astros-Twins Same Game Parlay Options

For all the flak they have been getting all year, there have been a couple of positive things about the Astros season and one of them has been the individual brilliance of Yordan Alvarez. With a .316 batting average, the 28-year old Alvarez has been filling up the stat sheet this season with 15 home runs, 31 RBIs, and 55 hits in 48 games played.

Considering that the Astros have no other reliable run producer outside of him, then we are keen on Alvarez to get himself going here once again. We are really liking the RBI and hits line on him although we’ll try to be more conservative and back the three-time All-Star to record at least two hits here. Against an Astros pitching team that has struggled to suppress hard contact, Alvarez should have numerous chances to square the ball up if he continues to see pitches in hittable zones.

Ryan Jeffers to record an RBI
Under 8.5 total runs

On the other hand, the Byron Buxton hits line is something worth considering here with how the two-time All Star has been finding ways to stay productive but we are going out of a limb and backing the Ryan Jeffers RBI line and the under 8.5 total runs to complete our Underdog same-game parlay. The 28-year old Jeffers has slowly developed into a reliable situational hitter this season with his ability to create damage when there are runners in scoring position.
