In his third game, he hit a lead-off home run against the Washington Nationals, as well as one against the New York Mets in his fourth game. Oeltjen hit his three home runs in his first 20 at bats. He also came one hit shy of the cycle in a four hit game on 11 August. The four hits meant that he became the fifth player in the "expansion era" since 1961 to have twelve hits in the first five major league games played.
