How is Marcus Semien performing?

Marcus Semien is a contact-first shortstop through 141 games with modest power conversion. His 18.3% barrel rate shows consistent hard contact, but a 5.8% home-run rate and .083 ISO reveal he's not translating those barrels into extra-base hits at typical rates. An 8.3% strikeout rate is disciplined, though a 15.3% whiff rate still creates gaps in consistency. With a 1.5% stolen-base rate, his offensive value depends on whether he can improve power output from his quality contact.
