The Blue Jackets made their first trade of the season and first in the career of GM Jarmo Kekalainen today, acquiring Winnipeg forward Spencer Machacek in exchange for forward Tomas Kubalik. Machacek, 24, was a third-round pick of the Thrashers in 2007. He has two goals and seven assists in 25 NHL games with Atlanta and Winnipeg but has spent the vast majority of his career in the American Hockey League (93-132-225 in 341 AHL games). The 6-1, 195-pound right wing had 11-14-25 in 57 games with AHL St. John’s this season. Kubalik, 22, was selected by the Jackets in the fifth round in 2008. The Czech native has 1-3-4 in 12 games with Columbus and 49-47-96 in 190 AHL games (14-6-20 for Springfield this season). Both players are considered mid- to-upper-level prospects. Kubalik (6-3, 215) was hoped to fill a role as a power forward in the vein of R.J. Umberger but had fallen out of favor in recent seasons. His last recall was an eight-game stint in Jan. 2012.
