The one knock on Mike Trout in his first few seasons was his tendency to swing and miss at high fastballs.

The Kansas City Royals exposed the one hole in Trout's game at the plate during the playoffs to great success last October.

Trout has gone after roughly 40% of high fastballs over the 2014 and 2015 seasons, but his contact rate has changed significantly. The Los Angeles Angels outfielder had a 74% contact rate on high fastballs last season, but that percentage has jumped to 89% this year.

He swung through 120 high fastballs in 2014, but through Monday night he had swung through just nine. It's early in the season, but it seems as though Trout has taken a significant spot forward.

Trout had a .356 slugging percentage on high fastballs last season, but is slugging .784 on such pitches in 2015.
