Chivas USA receives a player with plenty of experience, while Seattle will now be better positioned to sign players returning to MLS.
Rosales, 32, spent three seasons with the Sounders. He played a total of 86 games (73 starts), scoring 12 goals and adding 34 assists, and was named the 2011 MLS Newcomer of the Year. The Argentine was on Seattle's list for the Re-Entry Process, which begins Thursday, meaning the Sounders secured a return for a player they were set to lose anyway.
"Mauro has been an important part of our organization, both on and off the field, for the past three years," Sounders general manager Adrian Hanauer said in a team release. "It will be difficult to see him leave, but our salary cap situation made this decision necessary. We wish Mauro the very best at Chivas."
Bowen, 22, became the league's first Homegrown Player upon signing with the Galaxy back in 2008. In 2013, he set career highs with 15 starts and 1,173 minutes while scoring twice and adding a pair of assists.
