CINCINNATI (AP) — White Sox designated hitter Eloy Jiménez was hospitalized on Saturday due to abdominal pain.

“He had some abdominal pain last night and it intensified throughout the night,” White Sox manager Pedro Grifol said. “This morning we took him to the hospital for further evaluation and he’s still there. We should know something shortly.”

The White Sox released an update on Twitter on Jimenez’s condition after their 5-3 loss to the Cincinnati Reds Saturday, saying the star slugger underwent an appendectomy at Cincinnati’s Good Samaritan Hospital and is expected to be discharged Saturday night.

The team also said Jimenez will return to Chicago, where his expected recovery time will be about 4-6 weeks.

Jiménez is on a season-high eight-game hitting streak after going 1 for 4 with a single and two strikeouts in Friday night’s 5-4 win over the Cincinnati Reds. He went 3 for 5 with a homer and three RBIs on Thursday.

“Any time you have to go in with abdominal pain, it is scary,” Grifol said. “I talked to him this morning, and he said it hurt when he moves. It intensified a little bit, so we’re erring on the side of caution to see what it is.”

The White Sox (11-23) have won four of their last six games after a poor April. Yasmani Grandal filled in at designated hitter on Saturday, with Seby Zavala catching.
