Dodger Stadium, as noted above, is a pitcher's park. Has been a pitcher's park since Sandy Koufax was a young man. What it's not is tough on power hitters; over the last three seasons, Dodger Stadium's been one of the easier home-run parks in the National League. So why is it a pitcher's park? Because it just crushes doubles, triples, and batting average in general. Remove home runs from the equation, and Dodger Stadium is the pitcher-friendliest park in the league.
Derek Lowe removes home runs. The ballpark removes everything else. And suddenly we're looking at a pitcher who might, with just average luck and a good defense, post an ERA in the 3.50 range.
That article is normally subscription only, but apparently if you copy the URL listed for the article on ESPN's site, and replace the word "proxy" with the word "lite", and the words "column/story" with "columnist" (i.e. "http://proxy.espn.go.com/mlb/columns/story?id=1963581" becomes "http://lite.espn.go.com/mlb/columnist?id=1963581"), you can read the protected articles. Neat. [I will also point out that it can be flakey at times.]
On the subject of J.D. Drew, here's another bit of contract chicanery for veejane to add to her Scott Boras files. Apparently Drew's new contract with the Dodgers ($55M for 5 years) has a clause that allows him to declare himself a free agent again after two years if he "puts up big numbers," whatever that means. Note that the Dodgers are still forced to pay him if he puts up crappy numbers.
