In December 2015, Pačėsas signed on as the head coach of Lietuvos rytas. He helped Rytas win the King Mindaugas Cup, but suffered a disastrous 3rd-place finish in the LKL after losing to Neptūnas in the semifinals. In June 2016, he extended his contract for one more year. The 2016-2017 season was even more disastrous, as the team struggled in the LKL and failed to qualify to the Eurocup playoffs. In February 2017, Pačėsas resigned, and left Lietuvos rytas.
Note: The EuroLeague is not the only competition in which the team played during the season. He also coached in domestic competition, and regional competition if applicable.
