A group of six pitchers that includes White Sox right-hander Hector Noesi has used a Kevlar padding insert in caps this season or in spring training that MLB has not approved, the manufacturer told ESPN's "Outside the Lines" on Sunday.
Rob Vito, CEO of Unequal Technologies, said Noesi and Yankees reliever Esmil Rogers have worn the company's "Dome" insert under official New Era caps in games this season. Four other pitchers he declined to name have also worn them in the last six weeks.
