Passage: Culberson was signed by the Dodgers in November 2015 and invited to spring training, where he impressed new Dodgers manager Dave Roberts. After an injury to Howie Kendrick opened a spot for him, Culberson made the Dodgers 2016 Opening Day roster. He was designated for assignment in July and optioned to the Oklahoma City Dodgers, then recalled a month later. Culberson ended the big club's final home game of the season with a walk-off home run against former Rockies teammate Boone Logan, clinching the Dodgers' fourth consecutive National League West division title. He played in 34 games for Los Angeles, hitting .284 and in 70 games for Oklahoma City, hitting .260. He had no hits in seven at-bats with two strikeouts in the 2016 National League Division Series. He was outrighted to the minors and removed from the 40-man roster on December 9, 2016. He was assigned to Oklahoma City to begin the season. He remained in the minors for the conclusion of the AAA season, hitting .250 in 108 games and returned to the majors with the Dodgers on September 4. In 15 games for the Dodgers, he hit .154 with two hits in 13 at-bats. When starting shortstop Corey Seager was left off of the 2017 NLCS roster because of a back injury, Culberson was added to the post-season roster. He appeared in all five games of the series, with five hits in 11 at-bats for a .455 average. In the 2017 World Series, Culberson had three hits in five at-bats, including his first career post-season home run, which he hit off Chris Devenski of the Houston Astros in the 11th inning of Game Two.

Passage: The Poles are the most numerous of the West Slavs and occupy what some believe to be the original homeland of the Slavic peoples. While other groups migrated, the Polanie remained in situ along the Vistula, from the river's sources to its estuary at the Baltic Sea. There is no other European nation centred to such an extent on one river. The establishment of a Polish state is often identified with the adoption of Christianity by Mieszko I in 966 CE (see Baptism of Poland), when the state covered territory similar to that of present-day Poland. In 1025 CE, Poland became a kingdom. In 1569, Poland cemented a long association with the Grand Duchy of Lithuania by signing the Union of Lublin, forming the Polish–Lithuanian Commonwealth. The Polish–Lithuanian Commonwealth was one of the largest and most populous countries in 16th- and 17th-century Europe.
