I believe this may be a little bit of a fluke, but...
Matt Lindstrom @ home in 2009: 10.59 ERA
Matt Lindstrom @ road in 2009: 0.75 ERA
No doubt about the fact that Lindstrom hasn't been particularly good this year. He's only blown two saves this year, but with a xERA of 5.06, it's hard to argue he's been an effective closer.
Thing is, Matt Lindstrom wasn't much better last year either, with a x4.64 ERA. His 2008 ERA of 3.14 was the product of significant luck. So too was the 3.09 ERA he posted in 2007.
More bad news: Lindstrom seemingly "recovered" in the 2nd half of last season, posting a 4.45 ERA in the 1st half and a 1.86 ERA in the second half, but it was largely the product of a mirage. His K/9 fell significantly, and while he improved his command, the results on a peripheral front largely were a wash.
My conclusion is that Lindstrom has NEVER been a great reliever on the major league level and can't be dominant without being wild nor maintain control without giving up his dominance.
The Florida Marlins are surprisingly only 3 games out of first place at the moment and they'd be wise to make a switch. Right now, Nunez and Meyer seem the two logical choices, and Lindstrom owners would be wise to take a handcuff.
