There seems to be some confusion on whether Orioles second baseman Brian Roberts is seeing Pittsburgh-based concussion specialist Dr. Michael Collins today or tomorrow. The latest that I've heard is tomorrow so I'll cautiously go with that for now.

The good news is Roberts has really picked up the amount of physical and baseball activity that he is doing, and he has far more good days than bad ones these days. The bad news is he's still not completely symptom free and he still is experiencing some headaches from time to time.

I would suspect that he won't get completely cleared until he stops experiencing occasional headaches and dizziness, but I'll leave that to the doctors.

In other news, he has rescheduled his annual Brian's Baseball Bash - a fundraiser for the University of Maryland Children's Hospital - for Aug. 28 at Dave & Buster’s in Arundel Mills Mall. The event was originally scheduled for July 24.

All purchased admissions will be honored automatically for the new date. In the event that ticket holders cannot attend on the new date, refunds may be obtained by calling Krista Ellis at (410) 328-6064 or emailing kellis@umm.edu.

“Brian's Baseball Bash is very close to our family's hearts,” Roberts said in a statement. “Each year [his wife] Diana and I look forward to the opportunity to host this event and raise financial support and awareness for the University of Maryland Children's Hospital. Due to my current status on the MLB disabled list, we have decided to push the date of this year’s Bash back to August 28 to ensure that we will be in attendance. We thank everyone for their understanding and their support, and we’re looking forward to making the 6th Annual Brian's Baseball Bash another huge success!”
