Your logic contradicts itself. Stop me if I'm missing something: 1) You think a one run lead in the 10th safe, since Ramirez's run would only be "insurance." 2) Pinch running for a normally slow runner coming off a knee injury is an idiotic move because the game might be extended to the 11th inning and we'd need Ramirez's bat. Doesn't make sense. If you think Ramirez's run isn't important, that must be because you don't think the game will go to extras. Thus, it doesn't matter if he comes out of the game for pinch runner. At worst, RR's decision is inconsequential. In reality, though, you want as many runs as possible in that inning. We all know our pitching is suspect. It would be silly to keep a usually slow Ramirez in the game with a knee that's less than 100% at that point because it means either a) Sedar won't send him if there might be a play at the plate or b) he could aggravate the knee if he has to slide into/collide with the catcher. The sensible thing to do is pinch run for Ramirez to increase your chances at scoring an insurance run, thus decreasing the chances of going to another extra inning. If the pinch runner doesn't get a chance to score, there's still a good chance the game ends in the bottom of the inning, anyway.
