In the last 4 1/2 days I've had two out-of-town guests, made it to 2 Sox games, put almost 600 miles on my car, and drank 721 beers. (Roughly. And never while driving.) Hence my disappearance. I now have an absolutely insane 12 days ahead -- have to get tons of stuff done before vacation. So anything I type on this site the next 2 weeks will be a clear sign that I'm in serious procrastination mode.
...So anyway, you can always find all sorts of splits describing how players perform under certain circumstances. But one I haven't seen much of is splits for when the team wins versus when it loses. Obviously, almost by definition, most players should perform better in wins than in losses. But I can't imagine for most it's a massive difference. However, this season, Manny bats .355 in Sox wins, .198 in Sox losses; 27 of his 33 HR are in Sox wins. That strikes me as a huge difference, pointing just to how much the Sox rely on Manny to win (all his stats are similarly lopsided, but I chose just the ones which are essentially independent of what other teammates do). When he struggles, they lose; when he hits, they win. And the Sox almost traded him for Mike Cameron and Aubrey Huff. Awesome.
Also, this didn't take long.
