(All stats through Friday's games)
In 2012, Mike Trout enjoyed what many consider the greatest age 20 season ever for a hitter, posting a 169 OPS+ that bested the likes of Ty Cobb (167 OPS+ in 1907), Mel Ott (165 OPS+ in 1929), Al Kaline (162 OPS+ in 1955) and Mickey Mantle (162 OPS+ in 1952). What has the Millville Meteor done for an encore?
He has gotten even better...naturally
Still hitting for average and power, Trout has boosted his on-base percentage (from .399 to .425) and sports a 181 OPS+, trailing only AL MVP nemesis Miguel Cabrera (200 OPS+) among qualified hitters this season. He's once again smoking the competition among hitters in his age bracket, beating luminaries including Jimmie Foxx (173 OPS+ during his age-21 season in 1929), Eddie Mathews (171 OPS+ in 1953) Rogers Hornsby (169 OPS+ in 1917) and Cobb (169 OPS+ in 1908).
Trout has improved his already historic hitting this season by tightening his strike zone and making more contact, leading to more free passes and fewer punch outs (his walk-to-strikeout ratio has improved from 0.48 as a rookie to 0.78 in 2013).
Here's a closer look at Trout's more refined approach at the plate.
- Trout already had a pretty good eye at the plate, chasing just 24.9% of pitches thrown out of the strike zone as a rookie. His plate approach is even more refined in 2013, with his chase rate falling to 22.1%. For comparison's sake, the big league average is around 27%.
- He's doing a particularly good job of laying off fastballs out of the zone. Trout's fastball chase rate (16.8%) is ninth-lowest among MLB hitters and well below his 2012 clip (21.6%). Showing more restraint against fastballs thrown off the plate has helped Trout lift his batting average against fastballs from .306 to .345 this season.
- Trout isn't just chasing fewer pitches out of the zone -- he's also swinging at more strikes. His swing rate against pitches thrown over the plate has increased from 54.2% in 2012 to 55.8% in 2013.
- Trout has also cut his miss rate from 20.4% in 2012 to 18.8% in 2013, which has helped him punch out less often (21.8% in '12, 16.9% in '13). Once again, Trout has made the most progress against the heat: his miss rate versus fastballs has declined from 19.9% to 13.4% (the MLB average fastball miss rate is about 16%).
He's connecting far more often on fastballs thrown in the upper third of the strike zone
