So? All players do this. If you want to make the case the Bohm does it too frequently... well, make that case (good luck with that, at least this spring). One bad at-bat tells us exactly nothing... about any hitter.
Bohm has not had a good spring. But he's struck out four times, in 34 plate appearances. He's walked three times. A BB% that's approaching 10% is generally considered good. A K% that's a little under 12%, in the modern game, is also pretty good. His BA is low (.226) - he's 7 for 31. If he had all of two more hits in those 31 AB, he'd be batting .290. Small (tiny) sample size will do that.
The issues with Bohm, at this point, are: 1) defense; and 2) power. Not the occasional strikeout - certainly not if he's striking out only 12% of the time. Now, it's a small sample, and Bohm's K% last year was more like 27%, which is not good. His numbers this spring may be a fluke, or they may reflect a real improvement. Small sample = Who knows?
