Out of contract following 2018 season.
The Sounders captain is in his 10th season with the club since joining Seattle for their inaugural 2009 MLS season. A dogged defensive midfielder who is known for his ball-winning ability, he has become the heartbeat of the sounder's midfield over his time there. The Cuban, nicknamed "the Honey Badger," is also affectionately known as "Ozzie" in Seattle.
INTERNATIONAL: Alonso served as the captain of the Cuban Under-23 side before being called up to the senior team in 2006. He earned 16 caps and scored twice over the next year before defecting to the US in 2007 with the Cuban national team at the CONCACAF Gold Cup in Houston. Alonso hasn’t appeared for Cuba since, and he earned his US citizenship in 2012.
OUTSIDE MLS: Alonso’s spent nearly his entire professional career in MLS, but it didn’t start there. He first signed for hometown club Pinar del Río on Cuba’s western edge in 2005, where he won a league title in 2006. He racked up 42 appearances for the club and scored 14 goals before defecting in 2007 and joining the USL’s Charleston Battery. Over the course of the 2008 season, he appeared 23 times, scoreing four goals and earning the league’s Rookie of the Year award. Seattle signed him shortly thereafter.
