"We're real happy to have Jonathan coming on board," said team co-owner Mark Moore. "He has a lot of experience in these cars, and he's really hungry. I watched him all last year and never saw him go backwards. That's the mark of someone with real ability and talent. Our hope is to do a good job for him and win some races with him.
Klein, a 19-year-old from Long Grove, Ill., finished second in the Indy Pro Series, as a rookie missing the championship by four points. He'll make his debut with the team at the Indy Pro Series Grand Prix of St. Petersburg doubleheader on March 31-April 1.
"For a while it was looking pretty grim for the year," said Klein, who will share the entry with team co-owner Tom Wood, who will contest the oval events. "It was getting down to the wire. I'm really glad that I was able to put a deal together with Tom Wood and Team Moore Racing.
"Bobby (Wilson) showed last year that the cars last year were up to par, so there's no doubt in my mind that we're going to be competitive. We're going to be the competition to beat."
Though Klein will only be running a partial schedule, he expects to run up front, race hard and 'not worry about the championship."
"I can be like Wade Cunningham last year," he said. "I only need to worry about winning races week in and week out. Last year, we never finished out of top 5 on road courses – we showed well. I hope to improve on that. I'm glad to be back in the series. Look to have as many wins as possible."
