The Cleveland Guardians are down in the Lone Star State facing off against the Houston Astros for a three game series this weekend. The two actually went head to head in Cleveland back in April, where the Astros took two of three on the road, winning games one and three. Now, back at home, they won last night by a score of 9-3, bringing their lead to 3-1 across the entire regular season series. Will the Guardians pull off a road upset tonight?

Cleveland Guardians vs. Houston Astros MLB Betting Insights
Jose Ramirez is hitting .239 for the Guardians this season with a .418 SLG and a 2.4 WAR
Houston has now extended their winning streak to three games after beating the Tigers in the final two of their series prior to beating the Guardians last night. Plus, they have no beaten Cleveland in two straight head to head matchups. Despite being in fourth place of the AL West, they are only three games out of first place. The race for the division is incredibly tight, and they will want to keep stacking wins, especially at home.
Cleveland is tied with the Chicago White Sox for the top of the AL Central, but they have dropped three of their last four. They are hitting just .229 as a team, but somehow are on top of the division. Can they turn things around with a lefty on the mound tonight?

Cleveland Guardians vs. Houston Astros MLB Picks
After an incredible May, Spencer Arrighetti has gotten pieced up during June. But tonight, I think he can turn it around.
Guardians vs. Astros Prediction: Astros Win and Cover, Over 8.5
Best Bet: Astros ML (-143) Lucky Rebel Sportsbook
I have no problem paying a little juice to back Spencer Arrighetti. This guy was one of my favorite fades in the past, but I have to respect the performances he has been putting on this season. Now, he was a flame thrower during the month of May, posting a 0.93 ERA and a 1.14 WHIP. Things have been a bit different in June, but this could be a great spot for him to turn things around.
He faces a Guardians team that only hits .229, with that average dropping to .219 on the road. They also only hit .224 against righties, and now during the month of June, this team hits just .214. That is not going to get you results.
The Guardians are decent at drawing walks, and Arrighetti gives up plenty, but Cleveland's walk rate significantly declines on the road and when facing righties. The Astros should have no problem winning this game, as I do not see the Guardians contributing much at the plate.
