Kemp Taking Quality AB’s

Dodgers center fielder Matt Kemp looks like a star. A 6-2, 230 pounder with a breath-taking power/speed combo, Kemp made his major league debut back in 2006 after mashing in the upper levels of the minors (including a career .350/.403/.551 showing at AAA). Kemp was understandably raw as a 21 year-old rookie back in ’06, with a .317 wOBA and a .253/.289/.448 line in 166 PA.

In 2007, Los Angeles’ sixth-round pick in the 2003 draft posted a sweet .383 wOBA, compiling a .342/.373/.521 triple-slash in 311 PA. In retrospect, it should have been apparent that Kemp’s output was a little over his head: his BABIP was an obscene .417. Kemp is an athletic sort who has generally posted high BABIP’s in the minors and majors, but a Ted Williams-like showing when the ball is put in play isn’t something that one can depend on.

With some correction on the BABIP front (.363), Kemp’s wOBA fell to .349 (.290/.340/.459) in 657 PA during his first full season’s worth of hacks at the big league level. However, while his 2008 campaign might look mildly disappointing on the surface, Kemp made strides in terms of controlling the strike zone. His walk rate increased from 5.2% in 2007 to 7.1% in 2008, and his Outside Swing Percentage dipped from a Francoeur-like 36.4% to 31.5% (the average was 25.4% in 2008). His Isolated Power remained largely the same (.178 in ’07, .168 in ’08).

The 25 year-old has further refined his approach in 2009. His wOBA is back up to .380 (.295/.365/.496 in 156 PA), and while his BABIP is .381, there’s reason to believe that he can sustain that level of production. Kemp’s walk rate has jumped again, up to a healthy 9.7%. The increased number of free passes relates to a further drop in chasing pitches off the plate or in the dirt: Kemp’s Outside Swing Percentage of 24.6% is right around the 24.4 percent major league average this season. In addition to the patience, Kemp has a career-high .201 ISO.

It’s been fascinating to watch the diverging paths that Matt Kemp and Jeff Francoeur have taken since breaking into the majors. Both were big, tools-laden hitters with ample right-handed pop from well-regarded farm systems. Yet, one stands on the verge of stardom, while the other hacked his way back to Mississippi for a brief period last summer. Kemp is essentially the anti-Francoeur: the toolsy youngster who has added polish to his game, only getting better as time goes on.
