Although no announcement was made by Fulham, Dempsey appeared in the Seattle squad to face Sporting Kansas City in the season opener on March 10, 2014. Dempsey had made a return to form, scoring a hat-trick against Portland Timbers, and recording braces against FC Dallas and the Colorado Rapids, leaving his goal tally at 8 in 5 games for 2014. He earned the MLS's Player of the Month award for April. Both Dempsey's 15 goals and 10 assists were MLS career highs, as Seattle won the Supporters' Shield, but were eliminated in the conference finals of the MLS Cup by eventual champions LA Galaxy.
