This year is just over one month old, but it seems like the Red Sox have been scuffling forever, doesn’t it? Besides that 10-day streak of pitching dominance, this year’s team just hasn’t felt like contenders to me. BUT small sample size, you say! Yes, I grant you that. There are certainly signs of hope. Carl Crawford is turning it on now, and Adrian Gonzalez’ power is showing up one month late. But when is it safe to say something according to the numbers we already have?
When stats start to mean something
Turns out sabermetricians have already gone and done the hard work for us. Here is a handy list of statistics and around how many plate appearances you need before they start to mean something. Given that most of our regulars have about 100-150 PA, that means we can only really draw meaningful conclusions about the following:
- Swing rate (50 PA)
- Contact rate (100 PA)
- K rate, LD%, Pitches/PA (150 PA)
Not a whole lot to go on. But let’s do the exercise anyway:
[* = 2009 stats, ** = career stats used]
You can see that most of the numbers fall into place, but there are some notable differences. Dustin Pedroia’s numbers are all out of whack. He’s swinging more at the dish and striking out almost three times as much as he did last season. His contact rate and line drive percentage are WAY down, which to me suggests some kind of injury. Is this a result of his offseason foot surgery? Could be. He may need some extra time off, which might actually be doable while Jed Lowrie and Marco Scutaro are both healthy.
