Timpone is the first person to hold the CMO role at MLB since 2016, when then CMO Jacqueline Parkes departed for a role a ViacomCBS.
Timpone previously helped drive brand strategy for Marriott International, The Walt Disney Company and Universal Studios.
“As Major League Baseball continues to invest in its marketing resources, Karin brings outstanding experience and accomplishments with a track record as a digital pioneer and marketing leader of major global brands,” said Chris Marinak, MLB’s chief operations and strategy officer, and Timpone’s new boss.
