Murton was a great hitter before he reached the big leagues, but he wasn't a great power hitter. His highest ISOP number in the minors was 2005, and that .156 He had a .200 in the majors due to kind of a fluke home run rate (he hit 7 home runs in 140 AB's in the majors compared to 8 in 313 AB's in double A of the same year, also his ground ball rate in 2005 was higher than it was in 2006). In 2006, he started off what his minor league numbers would indicate (.156 in April, .125 in May). By August and September, he had developed into a much better power hitter (.244, .228). I'll give you this-the staff should have worked harder with him in the offseason so that he didn't have to go through the slump he did, and the time off during the season probably prolonged the time it took him to learn this-but he did develop much more power over the course of last season, and I think a little more aggression helped him in that regard, so I credit Dusty and his staff for that. If there was one thing Dusty and his staff were all right at, it was developing power in hitters-unfortunately for the Cubs, the organization bringing up aggressive hitters (Patterson and Cedeno to name two) combined with Dusty's aggressive approach was a really bad combination, and so only hitters that had learned patience in other places (Lee, Ramirez, Barrett, Murton) really came into their own under that coaching staff.
