Seattle vs Washington Pick

  • Seattle vs Washington Spread Pick

Both teams have been strong thus far this season, as they're hovering around 500. Washington, however, will have the edge Saturday afternoon as they are at home with the better pitcher and better offense. Look for Washington to play into their strengths Saturday afternoon against a mediocre Seattle team. Take the Nationals on Saturday to do the work as they get the win at home against the Mariners.

  • Seattle vs Washington Over/Under Pick

Offensively, both teams have been up and down thus far this season, but each has seen ballooned totals as of late, with 2 pitchers on the mound with higher-than-average ERAs; expect both offenses to find success. Look for the over to hit Saturday afternoon in Washington as the Nationals do the job to get the win in Game 2 of this series against the Mariners.
