Dan McCarthyI've never been in a cab here because I just take the T everywhere, so I can't say anything for or against that plan. Here's the subway map:

To get to Fenway from Logan you'd take the silver line (which are buses) to South Station, then get on the red line inbound to Park St, then the green line outbound to Kenmore and you're there! My roommate said it takes usually takes about an hour and fifteen minutes to get from Logan to BC, which is at the very end of the green line. I'd guess it would take about 45 minutes to get to Kenmore, so you've got plenty of time.
