Manny Machado (knee) will do some sliding drills next week before getting a checkup with Dr. Neal ElAttrache on March 18. The sliding and running the bases will be the biggest tests for Machado's surgically-repaired left knee. The third baseman is hoping to receive clearance for all baseball activities when he visits Dr. ElAttrache. Machado remains hopeful of being ready for Opening Day, but it wouldn't be a surprise if the Orioles play it safe and start him on the DL.
