Cal Raleigh smashed his major-league-leading 53rd home run on Sunday as Seattle hammered the host Atlanta Braves 18-2. The 18 runs were the most for the M’s in a game since 2012 and they scored 28 runs over the final two games of the series. Eugenio Suárez homered twice in the win while Jorge Polanco and Josh Naylor also went deep. Luis Castillo allowed a run on four hits over six innings.

A four-run fifth inning was enough for St. Louis to beat the visiting San Francisco Giants 4-3 on Sunday. Lars Nootbaar and Iván Herrera delivered back-to-back RBI singles before Nolan Gorman worked a bases-loaded walk to key the big innings while Sonny Gray took a no-hitter into the sixth inning before faltering.
