It’s Time to Buy into Daniel Murphy
Yesterday, Daniel Murphy went 4-5, hitting his fourth home run of the season in the process, and driving his batting line for 2016 up to .398/.449/.663. His 192 wRC+ ranks third best in the big leagues, and he’s behind only Manny Machado, Dexter Fowler, and Mike Trout on the WAR leaderboards. In the aftermath of yesterday’s hit barrage, I sent out the following tweet.
Daniel Murphy for 3/$38M now looking like the free agent steal of the winter.

Many of the responses argued that Fowler is ahead in that race, which is certainly a reasonable argument given what he’s done for the Cubs thus far. A bunch of other responses were essentially along the “small sample size” lines, though. Like this one, for instance.
@DCameronFG Is there any reason to expect the 25 game sample to trump the 900 game sample that preceded it? We know who Daniel Murphy is.

In general, the premise of this tweet is mostly correct. When you have a large sample of a player’s career performance, you shouldn’t overreact to a 25 game hot streak, and believe that the most recent performance cancels out the longer history the player has provided for evidence of what he’s capable of doing going forward. In Murphy’s case, though, we’re well past the point of this being a 25 game hot streak. For most of the last year, Daniel Murphy has been one of the best hitters in baseball.
