The Twins have designated right-hander Liam Hendriks for assignment in order to clear a roster spot for the newly signed Phil Hughes, according to Tyler Mason of FOX Sports North (on Twitter).
Hendriks, who turns 25 in February, ranked sixth and seventh on the Baseball America's Top 10 Twins prospects lists from 2010-11. Though he has a solid track record in the minor leagues (3.61 ERA, 6.2 K/9, 1.6 BB/9 in 254 Triple-A innings), he's struggled tremendously in part of three Major League seasons.
Hendriks has pitched for the Twins in each of the past three seasons, totaling 156 innings. However, the Australian hurler has little to show for it, as he's posted a 6.06 ERA with 5.7 K/9, 2.7 BB/9 and a 40.4 percent ground-ball rate. Home runs have been a persistent problem for Hendriks, who has averaged 1.7 big flies per nine innings in his Major League tenure.
