Mike Trout Was Going Through a Thing
On Saturday afternoon in Anaheim, Mike Trout went 3-for-4 with two singles and a home run. For a player who, at age 26, has basically secured a place in the Hall of Fame, that kind of performance is pretty commonplace. Mike Trout is the best player in the world; nothing in this piece will attempt to convince you otherwise.
What was notable about that Saturday game, however, is that it represented Trout’s first multi-hit effort since since June 18th. If you’re the kind of person who takes life as it comes, for good or for bad, this sort of thing might not even register. But for the rest of you, who worry about the little moments in between the big ones, there is this: for the last two weeks or so, before he got three hits on Saturday, Mike Trout had been in a bit of a slump. For about two weeks or so, Mike Trout was a below-average major-league hitter.
Consider the following, which is a chart of Trout’s rolling wRC+ in 14-game chunks, dating back to the beginning of the 2012 season, which was his first full campaign, and concluding on July 6th, the day before his home run:

There are roughly 1,000 games here, so it’s pretty condensed. The most important part of it, however, is the low point on the right-most edge of the graph. That’s the slump Trout was enduring until Saturday, a 14-game stretch (June 22nd to July 6th) during which he recorded just a 70 wRC+. With the exception of that horrible second half he had back in 2014 and the very beginning of his 2012 season, it was the worst offensive period of his very excellent career to date.
A couple weeks spent hitting 30% worse than league average isn’t a news item for most players. Trout’s teammate Justin Upton has recorded just a 64 wRC+ over the last two weeks, for example, and that’s unlikely to inspire a post here at FanGraphs. Billy Hamilton owns a lifetime batting mark of 71 wRC+. For Mike Trout, however, this type of stretch is nearly unprecedented — and especially notable as it came hot on the heels of some of the best baseball in his glittering career.
