So let's put the spotlight on Sean Berry

Hitting coach Sean Berry has been in his current position since July 12, 2006, taking over on a full-time basis beginning with the 2007 season. Let's see how these last three years have gone. Below is a table with the three slash lines, and following each stat is the team's rank, out of 16 NL teams.

Year	Avg	OBP	SLG	OPS	OPS+
2007	.260 (12th)	.330 (10th)	.412 (10th)	.742 (10th)	91
2008	.263 (6th)	.323 (11th)	.415 (7th)	.738 (10th)	94
2009	.260 (8th)	.319 (13th)	.400 (11th)	.719 (12th)	90

Okay, so a few things here. Since Berry took over full-time, the Astros have not been in the Top 5 in a single slash line category. Now, to be fair, it's not like the Astros were the '27 Yankees in the years preceding his arrival (except for 2004, when the Astros were 7th/6th/6th/6th - but that has a lot to do with Kent, Beltran, Bagwell, and Berkman in his 28-year old season).

That said, this is pretty bad. And while the Astros will not likely be making any personnel moves anytime soon, We cannot lose sight of the fact that the Astros have been 10th, 11th, and 13th in the National League in on-base percentage, and their OPS+ has been on the wrong side of 100 in each of these years. With THAT said, it's debatable how much impact a hitting coach actually has. He can break down film and pitchers with the hitters all day, and when it comes gametime, Hunter Pence can forget all of it and chase breaking balls down and out of the zone. But still...
