The Washington Nationals' Ryan Zimmerman is slashing an abysmal .121/.203/.207 with an OPS of .410 to open this season. He has a wOBA of .194 coupled with a wRC+ of 15, with a measly seven hits and one home run in 67 plate appearances this season.
Those numbers are impossibly bad and, based on much of the underlying data, are almost certain to improve. Zimmerman's hard-hit rate of 46.3% is tied for 17th-best in baseball out of 192 qualified hitters, and yet he has just a .150 BABIP this year. His batted-ball data actually indicates some improvements over last year, when he hit .303/.358/.573 with a .930 OPS, 36 bombs, 108 RBI and 90 runs scored.
His ground-ball rate has decreased from 46.4% to 34.1%, while his both his line drive rate (from 19.9% to 26.8%) and fly ball rate (33.7% to 39.0%) have increased. His walk rate is almost exactly the same (7.6% to 7.8%) and his strikeout rate is only slightly higher, from 21.9% last year to 26.6% this season.
It is a virtual impossibility for Zimmerman's numbers to stay this low, so trade for him now while his numbers are among the worst in baseball. They won't stay there.
