PITTSBURGH — The Dodgers have had an illness running through their clubhouse lately.

And on Wednesday, it forced an alteration in their pitching plans.

While Shohei Ohtani was in the Dodgers’ lineup as designated hitter for their game against the Pittsburgh Pirates, the two-way star was scratched from his scheduled pitching start at PNC Park after feeling “under the weather” the past few days, according to manager Dave Roberts.

“When you’re sick and potentially dehydrated, the tax of pitching in a game wasn’t worth it,” Roberts said.

Instead, Emmet Sheehan will take the mound for Wednesday’s game, while Ohtani’s next pitching appearance will be pushed to “sometime this weekend” against the Baltimore Orioles.

“Just to give him a few more days to recover,” Roberts said.

Ohtani’s sickness certainly didn’t seem to hamper him at the plate Tuesday, when he had two doubles and a career-high 120 mph exit velocity on a solo home run –– his 46th of the season and 100th as a Dodger.

However, Roberts said Ohtani’s pregame catch play on Tuesday was cut short, and that the risk of overexerting the reigning National League MVP by having him make a full-length start Wednesday wasn’t worth it.

“The toll of taking four or five at-bats versus pitching five innings, there’s no comparison,” Roberts said.

Ohtani’s symptoms have included chest and sinus “stuff” as well as “a deep cough,” Roberts added.

Several other Dodgers players have dealt with similar issues recently. Max Muncy was so sick last week, the team sent him home to rest and delayed the start of his minor-league rehab assignment to this week.

“We’re trying to manage it,” Roberts said. “But there are guys that are just not feeling great right now.”
