Will Nate Remain Great?

Coming up through the minor league farm system, Pirates outfielder Nate McLouth seemed to fit the dreaded “fourth outfielder” archetype very well. A 25th-round selection in the 2000 amateur entry draft whom the Bucs managed to pry away from a Michigan scholarship, McLouth was viewed as possessing a good (but not great) bat and solid (but not center-field worthy) range. The main complaint about Nate was his power. (Generously) Listed at 5-11, 180 pounds, McLouth did not figure to have the pop to support his playing every day in a corner outfield spot.

Upon reaching AAA Indianapolis in 2005, McLouth appeared to affirm those extra outfielder predictions by batting .297/.364/.401. Nate showed a line-drive bat and excellent base running skills (34 SB, 8 CS) that figured to make him a well-rounded bench player, but the power was lacking (.104 ISO). McLouth got the call up to Pittsburgh late in the 2005 season and actually matched his AAA home run total (5) in just 120 PA with the Pirates, batting .257/.305/.450.

In 2006, Nate essentially filled that fourth outfielder role and had a difficult season, posting a .233/.293/.385 line in 297 PA. His walk rate dipped to 6.3% and his strikeout rate was rather high (21.9%), a surprising development for a guy who whiffed less than 14% of the time at the minor league level. Perhaps he was trying too hard to play the power-hitter’s game: he posted a decent .152 ISO, but it may have come at the expense of some hard swings and misses.

A funny thing happened in 2007. After once again filling the fourth outfielder role earlier in the season, McLouth was given a chance to play on a regular basis in August and September, and he exceeded most anyone’s expectations:

2007: 382 PA, .258/.351/.459, 10.6BB%, 23.4K%, .201 ISO, 16.4 LD%, .301 BABIP

A guy who barely managed a .100 ISO in the International League, McLouth posted an ISO exceeding .200 in ’07. His walk rate also improved, though his K rate crept a little bit higher. He was slightly lucky on balls put in play (his BABIP should have been about .284), but that’s not a huge difference. McLouth’s secondary skills were developing more than anyone had imagined, and he was just about the best base stealer in the game to boot (22 SB, 1 CS).

In spring training 2008, McLouth beat out Nyjer Morgan for the starting job in center field. Nate was a full-time player for the first time in his career, and he made the most of the opportunity:

2008: 685 PA, .276/.356/.497, 9.8BB%, 15.6K%, .221 ISO, 18.5 LD%, .291 BABIP

Nate’s 2.30 WPA/LI ranked 4th among center fielders and 17th among all outfielders, ahead of names such as Curtis Granderson and Vladimir Guerrero. His walk rate remained steady, and he significantly reduced his strikeout rate as well. McLouth’s contact percentages were 85.21% and 83.82% in 2006 and 2007, respectively, but he upped that number to 88.36% this past year. His ISO climbed to .221, which also ranked him ahead of Vlad and Granderson as well as Matt Holliday. Continuing his trend of stellar base running, Nate swiped 23 bases in 26 attempts. With 26 bombs and 23 steals, McLouth turned in a 20/20 season.

Given the opportunity to play on a regular basis and disprove his fourth outfielder status by new Pirates management, Nate McLouth turned in one of the better campaigns among all outfielders in 2008. While his Gold Glove Award was pretty dubious (John Dewan’s Plus/Minus system had him at -40 plays, 35th among CF’s) and he should likely defer center field to rangy prospect Andrew McCutchen, Nate has developed better power than anyone could have anticipated, given his minor league track record.

With two straight years of .200+ ISO’s, a solid walk rate, a reduced K rate and no fluky BABIP, it seems reasonable to think that he can retain this level of offensive performance going forward. Add in his nifty, high-percentage base stealing (he’s now 57 for 62 in the majors, or 91.9%) and you’re looking at a fantasy asset. Heading into his peak years (he just turned 27), McLouth has developed enough offensive ability that he could still be valuable as an everyday player in a corner outfield spot. Who would have thought that when he was slugging .401 in AAA?
