But, really, he probably already has all the knowledge he needs for the Saturday afternoon game at Camden Yards.
Jimenez, who is 2-5 with a 4.50 ERA in nine starts this year, will face the Cleveland Indians, the team he spent the previous 2 1/2 seasons with before joining the Orioles as a free agent this winter.
"I am going to take it like it is just another team, but I know it is not," said Jimenez, who was 26-30 with a 4.45 ERA in 74 career starts for the Indians from 2011-2013. "Almost all of them are ex-teammates I know, and I got along well with all of them."
Jimenez said he wasn't really looking ahead to his first game against the Indians — he never pitched against them when he was with the Colorado Rockies — until he saw the schedule for this week.
"Now that I know I am pitching on Saturday, I was like, 'Oh it's the Indians,' " he said. "But it is going to be fun."
He said he expects he will mingle with some of his old teammates Thursday and Friday, before trying to shut them down Saturday.
"I am probably going to go see them, because I got along with all of them well," he said. "We are cool."
Although he said he would have liked to return to the Indians when he became a free agent, Jimenez had a pretty good idea that they weren't going to spend the money needed to retain him despite his 13-9 record and 3.30 ERA last season.
"Baseball is a beautiful game, but it is a business, too," said Jimenez, who signed a four-year, $50 million deal with the Orioles. "They have a lot of young arms there, and they didn't feel they had a reason to have to spend so much money [on me]. They have a lot of young arms and they trust them."
