A rough week for Lucas Giolito got even worse Tuesday night after a rough start at Citi Field.

The Chicago White Sox right-hander announced on social media last week that he and his wife, Ariana Dubelko, have mutually agreed to end their marriage after more than four years together.

In his first start since the announcement, he allowed five runs in the first inning against the New York Mets as part of a tough outing.

He walked Brandon Nimmo to start the inning and scored on Tommy Pham’s double. Two batters later, Pete Alonso hit a sacrifice fly to make it 2–0. After striking out Jeff McNeil, he allowed back-to-back home runs to rookies Francisco Álvarez and Brett Baty that made it a five-run frame for New York.

Francisco Lindor added an RBI double in the second inning, and the nine-hitter DJ Stewart hit a solo home run in the fourth. Giolito was tagged out after allowing two more men to reach base, one of whom scored. In all, he threw 100 pitches in just 3.2 innings, racking up eight won on six hits and five walks.

Giolito, 28, made the announcement in a lengthy Instagram post during the Home run derby.

«After careful consideration and discussions, we have chosen to go our separate ways while maintaining the bond we have fostered over the years,» Giolito wrote. «While our decision to end our marriage is undoubtedly significant, each of us is committed to maintaining our friendship and supporting each other as we enter this new phase of our respective lives.»
