Grayson Rodriguez is having a solid year and possesses above average strikeout numbers. With that being said it doesn't get much tougher from a matchup perspective than the Astros who own the lowest K Rate in the MLB. Houston pairs the league's lowest K Rate with the 6th highest OPS (.734) making them a brutal matchup for opposing pitchers. It's also worth mentioning G-Rod has some drastic home/road splits and his ERA is over 2.0 runs higher away from Camden Yards. Houston has also hit the ball significantly better at home where their OPS is .114 higher. This number moved to 5.5 fairly quickly which is where it should have opened. I still lean under at 5.5, however wouldn't risk more than a half unit.
