This is a good one to fact-check the eye test on, because DeJong and O'Neill are both swinging at almost the exact same percentage of pitches (50 percent) this season.
And O'Neill is swinging at a slightly higher percentage of pitches outside of the zone (32.6 percent) than DeJong (31.5 percent.
They're swinging at nearly the same amount of pitches inside the zone (50 percent).
Compared to last season, DeJong has swung at a slightly higher percentage of balls and a slightly lower percentage of strikes.
O'Neill has swung at more of both.
More than anything I see O'Neill is just making a lot better and more forceful contact.
His hard-hit percentage is at 54.6 percent. A career-high.
DeJong's is at 35.5 percent, a five-percent drop from last season.
That overshadows O'Neil's higher strikeout rate than DeJong's.
