2013-14: Bartosak signed a three-year entry-level contract with the Kings in March 2014. He made his pro hockey debut with Los Angeles AHL affiliate Manchester on his 21st birthday — stopping 7 of 8 shots but being charged with the loss in relief of Jean-Francois Berube in 22 minutes of action in a 7-5 loss to Portland on March 29th — after joining the Monarchs following his third WHL season. Bartosak won all three of his starts for Manchester, finishing 3-1 with a 1.75 goals against and .941 save percentage. The Monarchs finished first in the Atlantic Division but were defeated by Norfolk in four games in a best-of-five first round playoff series. Bartosak did not appear in any playoff games.

2014-15: Bartosak attended training camp with the Kings before being assigned to AHL affiliate Manchester. Backing up starter Jean Francois Berube for the Calder Cup champion Monarchs in his first pro season, he was 13-8-5 with three shutouts in 28 regular season games and had a 2.23 goals against and .919 save percentage.

Bartosak returned to the Czech Republic, playing in 10 Extraliga games for HC Vitkovice and two games with second division club HC Sumperk. He was 6-4 with a 3.04 goals against and .894 save percentage with HC Vitkovice and was 0-2 with a 2.44 goals against and .915 save percentage with HC Sumperk.
Bartosak possesses game-stealing athleticism coupled with solid reads. He is an average-sized goaltender but plays bigger than his size and can be difficult to beat when he is focused. A shoulder injury hampered him in his first junior season with Red Deer but he has shown no lingering effects.
Bartosak returned to the Czech Republic in 2015-16 after being suspended by the Kings and his professional future in the organization is uncertain at this point. Already a long shot prospect as a late-round pick in an organization with a top goalie like Jonathan Quick and some very good depth, his legal issues have added to his challenge. Bartosak has some significant ability and is still maturing physically and refining the various elements of his game but his problems cloud things..
