Segura hit the dirt in pain but stayed in the game for two more innings before exiting. The Brewers said he'd suffered a bruised left thigh, and he will be reevaluated before Monday's afternoon game against the Cubs at Wrigley Field.
"I don't think it's all right," Segura said. "I think it was a little dirty. … He was across the base and when he slid, he brought his knee up and across."
Brewers manager Ron Roenicke had a different view of Parra's slide.
"Fine," Roenicke said. "He's going in there thinking he has to break up two. By the time he gets that close to Seggy, he doesn't know that [Betancourt] bobbles that ball. I thought it was fine."
Segura, off to a 9-for-20 start to his first full Major League season, said "I don't know yet" when asked if he believed he'd be able to play in the Cubs' home opener on Monday.
The Brewers could ill afford another player's absence. They placed third baseman Aramis Ramirez on the disabled list Saturday with a sprained left knee, and left fielder Ryan Braun missed all three games of the weekend series against Arizona because of a stiff neck. Braun appeared in the on-deck circle Sunday, but was unable to bat in the bottom of the 11th inning with two outs, a runner at third base and the Brewers trailing by a run.
In addition, the Brewers are already playing a man short on the bench, because they opted to start the season with 13 pitchers. That confluence of circumstances prompted Roenicke to handle Segura with caution.
"It tightened up some, and I thought it was better, looking at tomorrow and the next few days, getting him out of there instead of trying to keep him in that game and sacrificing the next few days," Roenicke said.
