The Red Bulls arrived in Arizona with two new names as trialists, and two more added competitors for the goalkeeping spot.

While venerable Frank Rost announced his retirement, GM Erik Soler and coach Hans Backe brought in two more young Americans to compete with the pair they already acquired this offseason.

Ray Burse is a 27-year-old MLS veteran who has nearly three dozen league starts under his belt with the Columbus Crew and FC Dallas. Most recently he has been with the Puerto Rico Islanders. Phillip Tuttle is a 24-year-old Notre Dame product who was picked in the second round of the 2011 Supplemental Draft by San Jose and spent last season as a backup on the Harrisburg City Islanders.
At the moment, the Red Bulls have just two keepers on the roster, Jeremy Vuolo and rookie Ryan Meara from Fordham. They could use a third, even to serve asa No. 3 keeper.
