San Francisco Giantsmanager Bruce Bochy will remain in a Miami area hospital overnight after "feeling ill," the team said.
The Giants did not offer any further explanation for Bochy's hospitalization, but said he is at University of Miami Hospital and is expected to return to the team on Tuesday.
The team will open a three-game series at Miami with bench coach Ron Wotus serving as manager in Bochy's place Monday.
San Francisco holds a one-game lead in the NL West and is just 6-15 since the All-Star break.
