Seattle is hitting only .225 and has been outhomered as a team by Paul Konerko of the White Sox. The M’s respond to the change with an 8 – 1 win over the Angels as Michael Saunders hits his first major league homer and Josh Wilson also goes deep. Jason Vargas is the beneficiary of the offensive outburst.
