one hundred runs in a season for the first time when he scored both runs in a 7–2 loss to Toronto on September 28. He finished the year with a .276 batting average and 172 hits. He struggled defensively, though, as he led the major leagues with a career-high 30 errors, and Red Sox fans soon began booing him after he only batted .228 in April. Rentería batted only .231 in the 2005 ALDS as the Red Sox would lose the division series to the Chicago White Sox in just three games. The Red Sox were also disappointed with his performance, and on December 8 he was traded to the Atlanta Braves for prospect Andy Marte. Atlanta Braves (2006–2007) Rentería started 2006 with a 23-game hitting streak (counting the final game of 2005, it was 24 games). The 23-game streak in 2006 was the second longest that year and the longest to open the season since Ron LeFlore started 1976 with a thirty-game streak. He missed nine games after straining his rib cage on April 15 against San Diego, but he was not placed on the disabled list. On May 8, he had four hits and hit two home runs for the first time since 2003 in a 13–12 win over the Cubs. On July 3, he hit his one hundredth career home run off Anthony Reyes in a 6–3 victory over St. Louis. He was selected to the 2006 All-Star Game after he batted .318 with nine home runs in the first half of the season. On August 17, he had his first hit in 24 at-bats in a 5–0 win over the Washington Nationals. He finished the year with a .293 batting average, fourteen home runs, and seventy RBI. His defense also flourished, as he only committed thirteen errors. On Opening Day (April 2) in 2007, Rentería hit two home runs (including the game-winning one in the tenth) in a 5–3 victory over Philadelphia. He became the third Atlanta Brave to hit two home runs on Opening Day, joining Fred McGriff and Joe Torre. From April 20 to May 12, he had an eighteen-game hitting streak, which was the longest by a Brave in 2007. During the streak, he had four hits for the twentieth time in his career on April 27 in a 9–7 victory over Colorado. On May 15, he hit two home runs in a
