Question: Which other Dodger player who was intentionally walked in their debut played professional baseball for the shortest period of time? Passage:Bellinger started in left field in his major league debut on April 25, 2017, against the San Francisco Giants, and had one hit in three at-bats, with an intentional walk. He was just the third Dodgers player in history to be intentionally walked in his debut (Chico Fernandez, Dick Nen). Bellinger's first major league hit was an infield single off Neil Ramirez in the ninth inning of the same game. Bellinger hit his first major league home run on April 29 off Zach Eflin of the Philadelphia Phillies and followed that by hitting a second home run in the same game, this one off Hector Neris. He was just the third Dodgers player with a twohome-run game among his first five starts, joining Charlie Gilbert (1940) and Yasiel Puig (2013). He hit his first grand slam on May 6, off Miguel Diaz of the San Diego Padres, as part of a career-high five RBI day. He was the first Dodgers player to hit five home runs within his first 11 games. Bellinger was named the National League Player of the Week for the first week of May. With nine home runs in May, Bellinger moved into a three-way tie with Joc Pederson (May 2015) and James Loney (September 2007) for most home runs by a Dodgers rookie in a calendar month. He was named the National League Rookie of the Month for May.

Passage:A part of the Province of East Prussia until after World War I, in 1920 Nemirseta was with the Klaipeda Region (Memelland) separated from Germany according to the Treaty of Versailles. It was put under administration of the League of Nations and controlled by French forces, until the 1923 Klaipeda Revolt, after which it was annexed by Lithuania.

The secret protocol of the MolotovRibbentrop Pact allocated it to the German sphere of influence.
