CHICAGO -- With outfielder Trevor Crowe on the 15-day disabled list after spraining his right shoulder on Thursday, the Astros called up outfielder/first baseman Marc Krauss from Triple-A Oklahoma City on Friday.
Krauss, a left-handed hitter, was batting .277 with nine home runs and 35 RBIs in 65 games for Oklahoma City this season.
"He's done a tremendous job," Astros manager Bo Porter said. "He did a tremendous job in Spring Training. He can play both corner outfield positions, he can play first base and he'll be able to DH some as well. It's a great opportunity to see what he can do here.
"He has really good strike-zone discipline. He's put together really good at-bats. He pinch-hit and went into the games late in Spring Training. He always seemed to come through in a big situation with a big RBI. He's an athletic kid. He can run. So we look forward to having him here, and hopefully, he can help us win some ballgames."
Krauss, 25, arrived Friday morning. This is his first stint in the Major Leagues.
To make room for Krauss, who will wear No. 59, on the 40-man roster, the Astros designated right-hander Ross Seaton for assignment.
Wrigley a special place for Porter, who played for Cubs
CHICAGO -- Friday's game against the Cubs was a homecoming for Astros manager Bo Porter, who was managing his first game at Wrigley Field.
"Wrigley will always be very special for me," said Porter, who was hired in September. "I got my first Major League hit here. It was the team I was drafted by and the team I made my Major League debut with. It'll always be a special place for me."
Porter was selected by Chicago in the 40th round of the 1993 First-Year Player Draft and played for the Cubs during the 1999 season. He collected his first hit against the Reds on Sept. 7.
Porter's time with the Cubs was brief (24 games), but it was long enough for him to develop an appreciation of Wrigley.
"One of the things I love about Chicago is the day games," he said. "You actually get to have a family life. You can sit down and have dinner with your family. That's one of the reasons we made this a family trip, because of the day games."
All three games of the series are day games, which changes the normal routine of the players.
"You have to be disciplined," Porter said. "That's what it comes down to. You know you have three day games. These guys are professionals. They'll get their rest."
