I agree about cutting down the extra basehit when the lead is only 2 runs. The first baseman should be hugging the line but a good 15 feet behind the bag. It's hard to tell on TV and the announcers never mention it, but look for it late in games. The first baseman holds the runner. He's not guarding the line and the second baseman is in DP dept moved toward second. It happens numerous times. Also, if the lead is 3 runs there is no need to guard the line either, just get outs. @ Jacko, I have seen this dozens of times with Jeter at bat in the 9th. They open up that hole huge and he is great at using it. He has way more hits through the hole in that situation than DPs. He's a master at using that hole. They play right into his hands.
Edit: I never really took note of it until a couple of years ago when a friend of mine pointed it out to me at a Yankee game. I started looking for it, and damn, it happens a lot. It is managerial and coaching laziness. They have a 3 run lead and they are thinking about what to say at the post game press conference. Admittedly, in the 9th inning they do the right thing more often than not, but what about the 8th inning with a 3 run lead-- they almost always play at DP depth and give up the hole. Start looking for it, and you will see it. To me, if you have a 3 run lead with 5 or 6 outs to go, you position the guys to get one out.
