Pitching for the Rockies last season, the 31-year-old right-hander was on the disabled list all of June with the same injury.
After hitting a leadoff double, Fogg strained the groin Thursday when he tagged up from third base to score on a Jeff Keppinger sacrifice fly. He had just sprinted home on the previous pitch, but was sent back to third base when Keppinger hit a ball to right field that was caught and thrown home, but was later ruled a foul ball.
Before Saturday's game against the Cubs, Fogg didn't actually know whether or not manager Dusty Baker had scratched him from the start. He just knew his groin still wasn't right.
"It doesn't look good right now, honestly," Fogg said. "Right now, it doesn't hurt, but it's not all there right now, that's for sure."
Baker isn't too sure about Fogg's future, as it pertains to the Reds' final 21 games of the 2008 season. When it comes to the groin, Baker, inspired by former colleague Don Newcombe, is more than likely to err on the side of caution.
"The groin's no joke. They're really tough," Baker said. "Everything you do starts with the groin: the windup, the push-off, running, getting out of bed, getting out of a chair. I don't care what you do."
Ramirez, who was promoted from Triple-A Louisville just last Saturday, will make his second career Major League start. Against the Giants on the night of his promotion, the 25-year-old right-hander went seven innings, allowed three runs on five hits and struck out six to pick up a no-decision. In relief of Fogg on Thursday against Pittsburgh, he retired nine consecutive batters in three perfect innings.
"Ramirez is doing really well," Baker said. "Now you'll see him against contending teams."
