Alex Crognale, a first-team All-American at Maryland, has signed a homegrown contract with the Columbus Crew of Major League Soccer, sources said. The 6-foot-5 center back joined the Crew's academy before enrolling at Maryland. He was the Big Ten Defender of the Year this season for the top-ranked Terps, who took an undefeated record into the NCAA tournament and lost to Providence in the second round. The aerial specialist had six goals this year. Crognale's Maryland teammate, German sophomore forward Gordon Wild, is not in the primary batch of underclassmen targeted by MLS for Generation Adidas contracts despite 33 goals in two seasons (16 at South Carolina-Upstate in 2015, 17 at Maryland this fall) .If the league does not pursue him, Wild is expected to return for his junior season in College Park. ... The LA Galaxy introduced Curt Onalfo as coach. Onalfo, 47, replaces Bruce Arena, who accepted the U.S. national team job two weeks ago. Arena and Onalfo are onetime head coaches of D.C. United, with which Onalfo played.
