Brian Roberts unsure what caused concussion-like symptoms

After sitting out the Orioles’ season finale yesterday for his sixth consecutive missed game Brian Roberts revealed that he’s been bothered by “concussion-like symptoms” that have led to “lack of balance and some headaches, and just stuff that hasn’t been a whole lot of fun.” Roberts, who missed nearly the entire first half of the season with a herniated disk in his lower back, is scheduled to undergo a cat scan today in an effort to find the cause of the headaches. Here’s more from the All-Star second baseman:

I don’t know 100 percent sure [what caused the headaches], but it was Monday night. In frustration, I whacked myself on the head with my bat in the ninth. I had my helmet on. It’s something I’ve done a million times, but I still can’t tell you for sure if that was it. But that’s the only thing that I can point to because that night and the next morning, I just didn’t feel good.

Buck Showalter is getting most of the credit for Baltimore’s late-season turnaround, and rightfully so, but getting Roberts back into the lineup was also key for the Orioles. They went 29-26 with Roberts in the lineup during the second half as he hit .287/.361/.403 in 245 plate appearances. He’s under contract for $10 million in each of the next three seasons.
