According to this tweet from reliable source: The Back Post, Kansas City are making moves and more may be ahead in the days ahead:

It seems that Santiago Hirsig is gone according to reports. Look for official confirm soon and 1 more move

Midfielder Santiago Hirsig originally came to the Kansas City Wizards in 2009 from the Argentine Primera Division side San Lorenzo. According to reports he now departs to Argentine second division side Quilmes AC. Quilmes is the club where Seattle’s Miguel Montano came from.

It would also appear that Kansas City is making room for another incoming player.

Here’s what excellent Kansas City Wizards blog Down the Byline is reporting:

Hirsig Out of KC

Reports out of Argentina today indicate that Wizards midfielder, Santiago Hirsig is out with the Wizards. According to Quilmes Presente, Hirsig has signed on to play with Quilmes Atletico Club. Quilmes was promoted this past season to the Argentine Primera Division. Hirsig’s move gives the Wizards the roster spot they needed to create with the signing of Nikos Kounenakis.

Hirsig made 27 appearances for the Wizards over the course of his time in KC, 25 of them starts for 2,155 minutes. He scored his one goal in KC’s 3-2 loss last year to Seattle.
