March/April On March 31, the Orioles won their 2014 regular season opener against the
Boston Red Sox, but then proceeded to lose their next four games. After a full week and a 4–2 loss to the
New York Yankees, the Orioles were in last place in the
American League East and 3 games below .500. Orioles All-Star 3rd baseman
Manny Machado, still recovering from off-season surgery, did not play in any games for the Orioles during the month of April; but Orioles catcher
Matt Wieters got off to an uncharacteristically fast start hitting .338 with 4 home runs and 15 RBIs. The Orioles finished the month with 11 wins and 12 losses.
May Tommy Hunter started the season as the Orioles closer and was successful in 11 of his 12 save opportunities, but he blew 2 consecutive saves on May 10 and 13 and then was placed on the 15-day disabled list. On May 11, the Orioles placed catcher Matt Wieters on the disabled list. Wieters was hitting over .300 and would ultimately be lost to the team for the entire season. The Orioles finished May with 15 wins and 15 losses but moved up to 3rd place in the American League East. The one bright spot in an otherwise mediocre April–May was the torrid hitting of new Oriole
Nelson Cruz; by May 31 Cruz led all of MLB with a staggering 20 home runs and 51 runs batted in.
June On June 6, the Orioles lost to the
Oakland Athletics, 4–3 in 11 innings, dropping them 6 1/2 games out of first place. It would be the farthest out of first that the Orioles would be all season.
Utility player Steve Pearce, who had appeared in only 3 games for the Orioles in April, batted .361 in June with 5 home runs and 13 RBI's. The Birds finished the month with 16 wins and 12 losses, trailing the first-place Blue Jays by one game. and the Orioles led the American League East by 1.5 games. Orioles 3rd baseman Machado injured his right knee on an awkward swing against the New York Yankees on August 11. After going on the
disabled list and trying to rest his knee, he decided to have his knee surgically repaired thus ending his season. Oriole shortstop
J. J. Hardy batted .322 for the month with 5 homeruns and 18 RBI's. First baseman
Chris Davis filled in for Machado at third and hit 7 homeruns with 17 rbi's for the month. The Orioles ended the month of August with four consecutive wins; increasing their lead in the American League East to 9 full games over the second place Yankees.
September The Orioles started the month with a 6–4 loss to the Minnesota Twins but still maintained an 8 1/2 game lead over the second place Yankees. On September 7, the Orioles beat the
Tampa Bay Rays 7–5; Nelson Cruz went 4-for-5 with two home runs and 7 RBIs. On September 12, Orioles' first baseman Chris Davis was suspended for 25 games for testing positive for
amphetamine. Davis claimed he tested positive due to the use of adderall—for which he previous had a "therapeutic use exemption" but did not have for the 2014 season. On Tuesday, September 16, the Orioles clinched the American League East championship by beating the second place Toronto Blue Jays 8–2. The Orioles had not won an American League East title since 1997 and Tuesday marked the first time since 1969 that the Orioles won a division title in front of their fans at home. Steve Pearce, who had replaced Chris Davis at first base, blasted a three-run homerun off Toronto right-hander
Drew Hutchison to give the Orioles a 3–1 lead in the first inning. Oriole right-hander Ubaldo Jiménez, who hadn't been in the starting rotation for a month, picked up the win. The Orioles 401 walks were also the fewest walks as the modern Orioles and their 44 stolen bases were their fewest since 1961.
