Baltimore Orioles -1.5 over Houston Astros (+105)

To start off our MLB parlay, I’m going with the Baltimore Orioles on the run line. Fewer teams are hotter than the O’s at the moment, and that hot streak should continue on Friday against the Astros with budding star Grayson Rodriguez on the mound. Meanwhile, Astros starter Jake Bloss is making his MLB debut against a very difficult lineup. Rodriguez (3.20 ERA) will have a challenge on his hands against an excellent Houston lineup, but the young right-hander has been in great form over the last month, including tremendous outings against the Yankees and Phillies. On the other side, Baltimore’s lineup is hitting .273 and has an OPS of .806 in its last 10 games, while also ranking 7th against right-handed pitching this season. The O’s simply have too much firepower on the mound and at the dish, so let’s back Baltimore on the run line.

Chicago White Sox vs Detroit Tigers Under 7.5 (-118) 

For the second leg in our MLB parlay, I’m going with the under in this AL Central matchup between the White Sox and Tigers. These teams have been pretty miserable of late, with the Tigers having lost 4 in a row and scoring a total of 3 runs in those games, while Chicago has been the worst team in baseball all season long and shows no signs of improvement. At the very least, the starting pitching hasn’t been a major issue with either team. The White Sox will throw out Erick Fedde (3.09 ERA), who has made 4 straight road starts and has become quite reliable, allowing 2 runs or less in 5 of his last 8 outings. Detroit will counter with Jack Flaherty, who is riding a 16.2-inning scoreless streak stretching across his last 3 starts, and he has only allowed 6 hits during that span. Both pitchers should cruise against these anemic offenses, so let’s back the under in Detroit.

Kansas City Royals vs Texas Rangers Under 8 (-110) 

To close out this MLB parlay, I have the Royals and Rangers to go under 8 runs. Similar to the White Sox-Tigers game, these are a pair of lineups that are slumping of late. When Kansas City faces right-handed pitching on the road over the last 30 days, the Royals rank just 20th in wOBA with a wRC+ of only 89. Things aren’t much better for Texas, as the Rangers rank dead last in wOBA over the last 30 days when facing right-handed pitching, with a wRC+ of just 68. Nathan Eovaldi should produce a quality outing against a Kansas City offense that is far more threatening at home, while Brady Singer should take advantage of his favorable matchup against a Rangers lineup that is just not the same as it was a season ago. Let’s back another under and hope for a low-scoring affair in Arlington.
