She switched coasts in 2008, joining Pali Blues in Los Angeles, California as the first signing in team history. She joined Los Angeles Sol in the WPS in 2009, but only played one game for the club before she was traded to Saint Louis Athletica. She played seventeen games for Athletica, and gave multiple assists in helping the team go from the bottom of the ladder to second place and the playoff semifinal. Athletica then loaned her to the Central Coast Mariners, where she scored four goals in ten games as the Mariners finished second in the league. Athletica kept Fletcher for the 2010 WPS season, but surprisingly folded only six games into the season, all of which she started. Sky Blue FC picked up her contract and she became a regular player there as well, starting ten of the fifteen games she played with the Jersey-based club. During the off-season, she returned to Australia, this time with the Melbourne Victory – the Mariners had folded as well – and helped them to the semi-finals. Fletcher returned to the Sky Blue FC for the 2011 WPS season, and started all 15 games that she played and scored one goal. Like the previous season, Sky Blue was just short of making the playoffs. Following the end of the season, she returned to the Melbourne Victory for the fourth season of the W-League. She played in eleven games for the Victory during the 2011-12 W-League season where the team finished fourth during regular season play. After the WPS suspended operations in 2012, Fletcher signed with Vittsjö in the Swedish Damallsvenskan where she played for the 2012 and 2013 seasons. During the 2012 season, she scored one goal and started in all 21 games that she appeared. Vittsjö finished sixth during the regular season. After returning for the 2013 season, she scored 3 goals and started in all 22 matches for the team. Vittsjö finished in eighth place. In February 2014, Fletcher signed with Seattle Reign FC of the National Women's Soccer League for the 2014 season. Of the signing, Reign FC head coach Laura Harvey said, "Kendall adds experience and depth to our backline and potentially our midfield as well. She has proven professional experience in America, Australia and in Europe, which could prove vital for us in the coming season." Fletcher scored two goals as a defender for the team and helped them set a league record unbeaten streak of 16 games. The Reign won the league's regular season title (NWSL Shield) with a 16–5–6 record and 54 points – 13 points ahead of the second place team, FC Kansas City.
