Question: What year did the Los Angeles Clippers and Memphis Grizzlies face off, resulting in the Los Angeles Clippers to lose their first-round series in six games?

<P0-S0> The 2012–13 Los Angeles Clippers season was the 43rd season of the franchise in the National Basketball Association (NBA), their 35th season in Southern California, and their 29th season in Los Angeles. <P0-S1>  During the offseason, the Clippers signed seven-time all-star Grant Hill and re-acquired Lamar Odom from the Dallas Mavericks. <P0-S2>  They improved on their 40–26 record from the previous season to finish 56–26, and they won their first Pacific Division title in franchise history. <P0-S3>  The title was clinched after defeating the Los Angeles Lakers on April 7, which also completed a season sweep of their crosstown rivals, 4–0. <P0-S4>  The franchise had not swept the Lakers since 1974–75, when the Clippers were the Buffalo Braves. <P0-S5>  It was also the first time in 20 years since 1992–93 that the Clippers won the season series against the Lakers. <P0-S6>  Although this was enough to net them home-court advantage in a playoff series for the first time in franchise history, they lost their first-round series to the Memphis Grizzlies in six games. <P0-S7>  Following the season, Hill and Odom both retired and Chauncey Billups re-signed as a free agent with the Detroit Pistons. <SEP> <P1-S0> The Memphis Grizzlies are an American professional basketball team based in Memphis, Tennessee. <P1-S1>  The Grizzlies compete in the National Basketball Association (NBA) as a member team of the league's Western Conference Southwest Division. <P1-S2>  The Grizzlies play their home games at FedExForum. <P1-S3>  The team is owned by Robert Pera. <P1-S4>  The Grizzlies are currently the only team in the major professional North American sports leagues based in the city of Memphis. <SEP> <P2-S0> Darius Aaron Morris (born January 3, 1991) is an American professional basketball player for the Rio Grande Valley Vipers of the NBA G League. <P2-S1>  Morris was selected as the 41st pick in the 2011 NBA draft by the Los Angeles Lakers and plays the point guard position. <P2-S2>  He has also played for the Brooklyn Nets, Philadelphia 76ers, Los Angeles Clippers and Memphis Grizzlies of the NBA as well as the Los Angeles D-Fenders and Rio Grande Valley Vipers of the NBA D-League. <P2-S3>  With the Vipers, he established a D-League playoff single-game assists record in 2014. <SEP> <P3-S0> The Lakers–Clippers rivalry is a National Basketball Association (NBA) rivalry between the Los Angeles Lakers and Los Angeles Clippers. <P3-S1>  The two Pacific Division teams both play their home games at Staples Center in Los Angeles, inspiring their matchups to sometimes be called the "Hallway Series". <P3-S2>  The Lakers relocated from Minneapolis in 1960, while the Clippers moved from San Diego in 1984. <P3-S3>  Los Angeles fans have historically favored the Lakers. <P3-S4>  But the Clippers have sold out every home game at Staples Center since Feb. 2011 and entered the 2016–17 season with the sixth-longest active sellout streak in the NBA. <P3-S5>  The Lakers have won 11 of their 16 NBA championships since moving to Los Angeles. <P3-S6>  Meanwhile, the Clippers have made the playoffs only nine times since 1984 and were long considered the laughingstock of the NBA; in the history of the franchise, they have never advanced past the second round of the playoffs. <P3-S7>  Some contended that the term "rivalry" was inaccurate until the Clippers became more successful. <P3-S8>  For the first time in 20 years, the Clippers won the season series against the Lakers in 2012–13. <P3-S9>  This was the first of five straight season series victories for the Clippers, which included season sweeps in both 2014-15 and 2015-16. <P3-S10>  With the Clippers' 3-1 series win in 2016-17, the Lakers have now won the season series just four times in the past 13 seasons, with five Clippers wins, four Lakers wins, and four ties. <P3-S11>  The Lakers hold a 99–47 advantage in the all-time series against the Clippers. <P3-S12>  The two teams have never met in the playoffs.
