Stewart is a buy — expected wOBA says the production is earned.

He is making contact at star level and the results match. His expected wOBA is .350, .035 above the league average of .315, with 629 plate appearances — well past the 160 needed for that number to be reliable. His actual wOBA is .349, so there is no luck inflating the line. The contact quality backs it up: a 12.8% barrel rate against a league average of 8.0%, over 431 batted balls, a sample far past the 60 it takes to trust barrels. That is the standout driver. His strikeout rate (21.3%) and walk rate (9.5%) are right around league, so there is no swing-and-miss risk to worry about. His expected wOBA has climbed steadily across the season — the bat is real and still improving. Buy.
