Stewart is a buy — his bat is earning every bit of the line.

His hard-hit rate has climbed steadily across the season to 41.6%, and the trajectory matters more than the raw edge over league average. The contact quality is the story: 90.5 mph average exit velocity and an 11.9% barrel rate against a league mark of 8.0%, on a sample big enough to trust. His expected wOBA is .343, .028 above league, and his actual wOBA of .339 sits right beside it — no luck is propping up the line. His strikeout rate is right at league average, so there is no batting-average hole waiting to open up. Nothing here needs regression to fix it, and his expected number is still trending the right way. Buy.
