Iowa junior Zach Ortwerth is ready to step up as the Hawkeyes prepare to host UMass. The native of St. Louis is the Hawkeyes starting tight end after Addison Ostrenga was lost for the season after suffering an Achilles injury in a loss at Iowa State.

Ortwerth says the key for the starting tight end is run blocking.

Ortwerth says he worked to improve his run blocking during preseason camp.
