Lone Star Series was not conceived until , four years after interleague play began. It was only logical to have the Rangers and Astros matched together since they are the only MLB teams representing Texas. Since both played in two different divisions (AL West and NL Central, respectively), Major League Baseball had to rectify the oversight even though interleague play would not be rotated from division to division on a yearly basis until 2002. There has only been one rainout in the history of the Lone Star Series. A game scheduled for Sunday June 30, 2002, at Rangers Ballpark in Arlington was postponed due to rain and rescheduled for Monday, September 2. The Rangers won the last game of the year against the Astros, 7–2, in front of a crowd of 24,468, but the Astros won the Silver Boot regardless of the outcome of the game. On July 1, , Rangers outfielder Gary Matthews Jr. stole a home run from Astro Mike Lamb (a former Ranger) in what was considered one of the greatest catches of the decade according to MLB Network. At that time according to Lamb and Mark Teixeira, the Rangers-Astros "rivalry" was more for the fans in Texas than like a bitter rivalry (e.g. Windy City Series). Beginning in 2008, the Lone Star Series saw for the first time two African-American managers go head-to-head against one another, the Astros' Cecil Cooper and the Rangers' Ron Washington. This situation lasted for two years. On February 6, 2008, Nolan Ryan became the Rangers' team president after being the special assistant to general manager, scouting players, and holding pitching camps with the Astros for the previous three seasons. On August 18, 2009, the Rangers acquired Iván Rodríguez in a trade from the Houston Astros to help them down the stretch for the purpose of achieving their first playoff appearance in ten years. It was Rodriguez's second stint with Texas. The team had a winning season but did not qualify for the postseason. On September 14, 2010, the Astros' Triple-A affiliate, the Round Rock Express, announced that they would become the Rangers' new minor league affiliate. This change left the Astros without a Triple-A team and the Rangers' old Triple-A team, the Oklahoma City RedHawks, without a parent club. On September 20, 2010, the Astros made the RedHawks their own affiliate. These changes went into effect for the 2011 season. 2013–present:
