Softball... Who do I replace my shortstop with?

My JV shortstop/Best Player broke her ankle and will not play. I need to replace her, I have an accurate pitcher but not a lot of speed on her pitches. I know that every player is different and you can't answer this fully without knowing each players strengths and weaknesses but IN GENERAL, who should i replace her with? Im think another infielder would be best but should i move my second basemen over or my third. Knowing most hitters are right handed and my pitcher doesnt have too much speed, most balls will go to the left side. I think the second baseman is my best bet? Also, should i have my pitcher throw low and away on right handed hitters? Just nervous and trying to work things out in my head. Thanks
