Gerry Fraley of the Dallas Morning News shares the update:
The Texas Rangers acknowledged on Tuesday that left-hander Derek Holland underwent micro-fracture surgery on the left knee last week. The procedure underscores why the Rangers have said they are planning on Holland to be out until the All-Star break.
In the surgery, Rangers medical director Dr. Keith Meister created tiny fractures in the kneecap. The fractures are designed to stimulate the growth of new cartilage in the area.
Rangers right-hander Scott Feldman underwent the same surgery in November 2010 and didn’t make his 2011 regular-season debut until July 22. If Holland also requires an eight-month recovery, he could be out until August.
Holland, 27, registered an excellent 3.42 ERA, 1.286 WHIP and 189/64 K/BB ratio across 213 innings (33 starts) last season for Texas. The Rangers may have to turn to the free agent market to replace him.
