Royals vs Mariners Prediction

The Mariners won six of the previous ten H2H encounters, including three of the last four. Kansas City is 3-7 Over/Under in the last ten games, and although many of Seattle’s games went Over this season, mainly because of low run totals, I am going with Under here. With this pitching matchup, I have little doubt this one will be a low-scoring affair. Seth Lugo has been one of the best AL pitchers in June, when he posted a fantastic 1.26 ERA and allowed just two runs in his last four starts, along with two shutouts. Bryan Woo, on the other hand, is the Mariners’ best pitcher this season. He connected three quality starts, registered two shutouts, and surrendered only two runs in that span. Go with Under.
