The Blue Jays opened June with a three-game series against the Washington Nationals. The first game of the series was rained out and rescheduled as a doubleheader for the following day. In the first game of the doubleheader, Toronto was shut out for the first time in the 2015 season, losing 2–0. The team rebounded from their shutout and defeated the Nationals 7–3 in the second game, aided by Kevin Pillar's first career multi-home run game. In the rubber match, Toronto beat Washington, 8–0, and won their first series on the road since taking two of three from the Baltimore Orioles in early April. Mark Buehrle recorded his league-leading third complete game, and earned his first shutout of the season. He also pitched his second consecutive complete game, the first time he had done so in over a decade.
