I think you are referring to our very own Broxton.
That it was. Reds were up by a run or two at the time. Broxton came in and was sitting at, like 90 mph and couldn't get the ball past the Reds hitters. After going 1-0 on Rolen (I think), the Dodgers pitching coach came out, told Broxton something about his mechanics, and Broxton came back throwing 96+ and just blew away Rolen. Votto came up next, and had that ridiculous at-bat, getting beat badly on the first two fastballs. He choked up and started fouling everything off, eventually worked the count to 3-2, and then hit a little single to give the Reds another run.
