Zach Levine at the Crhon writes about JD Martinez, Fernando Abad and a couple others.
LINKMisc. on Martinez:
An outfielder all his life, Martinez moved temporarily to first base and began to have knee problems. He was diagnosed with patellar tendinitis, and it has bothered him ever since and caused him to keep close watch on it. “Some days it's better than others,” Martinez said. “This year it's a lot better because I've been monitoring it. It's not a big deal; it's just something that's going to bug me.”
