Bryce Harper shouldn’t be sent to the minors. He should be sent to the disabled list.
Before he suffered his injury, he was batting .312 with a .357 on-base percentage and .469 slugging. Since coming back from the DL his slash line is 0.213/0.298/0.291. His isolated power (slugging percentage minus batting average, which illustrates the ability to hit for extra bases), has plummeted.
Looking at the numbers, is that he either aggravated the thumb injury or it never healed 100 percent. Here are his splits for this year:
Not only is he hitting without power in August, he is striking out more and has yet to put a ball into right field with any authority.
For comparison, here is Harper’s hit chart for 2012, a season in which he was mostly healthy.
Even if we agreed a trip to the minors was a viable alternative, it wouldn’t do anything to heal his injury. For that, he just needs some rest.
