Doumit remained in the game to finish the inning, but when he returned to the dugout after grounding into a double play in the fourth, Doumit clearly wasn't himself.
"I remember running, but I felt like I was running in quicksand. It felt like I was going nowhere," said Doumit. "Once I got back to the dugout and started putting on my shin guards, I felt like I was going to faint, like I was going to pass out. That's when [head trainer] Brad [Henderson] stepped in ... I couldn't play, and I went to the hospital."
Doumit underwent a concussion test earlier on Saturday, and while he joked about how hard the visual test could be for someone who hadn't had a concussion, Doumit said the test went smoothly and that the team doctor recommended just a few days off to avoid any recurring dizziness.
Manager Jim Tracy said he had not yet consulted with team physician Edward Snell after the concussion test and was therefore unsure as to whether Doumit would be available to pinch-hit on Saturday or when he would be cleared to return to the lineup.
"I'm not ruling it out, but I'm not ruling it in. He has to talk with the doctor," Tracy said. "Then obviously, he needs some batting practice ... to see if anything else pops up between now and then."
Doumit did not participate in the team's batting practice on Saturday.
A few days off may also help Doumit regroup from a recent slump. The Pittsburgh catcher has cooled down over the past week after emerging as the most potent bat in the Pirates lineup earlier in the month. Doumit has only two hits in his last 18 at-bats.
Gorzelanny's a go: Like Doumit, the prognosis for pitcher Tom Gorzelanny on Saturday was a positive one.
Two days removed from being hit in the left thumb by a line drive off the bat of St. Louis' Aaron Miles, Gorzelanny said he was encouraged with his second sideline throwing session in as many days.
"It wasn't as bad as it was [Friday]," Gorzelanny said of the pain and swelling in his left thumb. "It was tough throwing the ball without feeling it [Friday], but then I got some treatment and went out and it felt good. Where we're at two days after, I'm feeling pretty good."
Pittsburgh pushed Gorzelanny's bullpen throwing session back one day to Sunday, and assuming that there are no unforeseen setbacks, Gorzelanny will be ready to take the mound for his next scheduled start on Tuesday in the Pirates' series opener against the Padres.
"I think I can do it," Gorzelanny said. "I don't see any reason why I can't."
Bay's launching pad: Cincinnati isn't home for Bay -- Trail, B.C., Canada, is for anyone checking -- but Bay could have you fooled with how comfortable he is at Great American Ball Park.
When Bay knocked out an Aaron Harang pitch in the second inning of Friday's game, it marked the 12th homer for Bay at the Cincinnati ballpark, which opened in 2003. The solo shot moved Bay into a second-place tie with Aramis Ramirez for the most home runs by a visiting player at the venue. Houston's Lance Berkman has 15.
"You don't really change [your approach] much," said the Pittsburgh left fielder of playing in the Cincinnati park. "For some reason you just see it better here. It's just one of those things. Obviously you look at the numbers and I know that they are fairly good."
That's putting it modestly.
After going 2-for-3 on Friday, Bay improved his average at Great American Ball Park to .357, which is the best among all Major Leaguers with a minimum of 100 at-bats.
"I knew I was close [to the top]," Bay said with a slight smirk. "You still have to go out there and play. It's not like you are guaranteed anything. It's definitely one of the better ballparks to play in, for me anyway."
Sizzling stats: The eight runs the Pirates scored in the 10th on Friday had Pirates manager of media services, Dan Hart, doing some scouring of the history books after the game.
Pittsburgh hadn't scored eight runs in an inning since July 9, 2004, when the team scored nine against the Expos in a game played in Puerto Rico.
The history books had to be flipped back even further to find the last National League team to score eight runs in the 10th inning. The Padres scored an NL- record nine runs in the 10th back in May 1995.
More important than any records the Pirates may have been close to setting in Friday night's final inning was the string of hits the offense put together with runners on base. After going 1-for-10 with runners in scoring position in three games against the Cardinals earlier in the week, the club had six hits in nine chances with runners in scoring position on Friday.
On deck: Ian Snell (4-3, 3.06 ERA) will be in search of his fifth win when he takes the mound against Kirk Saarloos (0-3, 5.09) and the Reds on Sunday at 1:15 p.m. ET at Great American Ball Park.
