In 59 seasons in Baltimore, the Orioles have started with 19 wins or more in their first 28 games only six times -- 1969, 1970, 1992, 1997, 2005 and, now, 2012.

The Orioles ran their current winning streak to five games following Sunday's 17-inning victory over the Boston Red Sox. Now, they face a tough nine-game homestand with the two-time defending American League champion Texas Rangers, Tampa Bay Rays and New York Yankees coming to Camden Yards.

Twice in history -- in back-to-back years in 1969 and 1970, in fact -- the Orioles were 20-8 through 28 games. In 1992, 1997 and 2005, the Orioles had the same record as this season -- 19-9.

A look at how those five teams performed after the 28th game:

1969 (20-8): The Orioles fell to 20-9 after losing, 1-0, to the Chicago White Sox at Memorial Stadium in the 29th game of the year. Catcher Elrod Hendricks collected two of the Orioles' five hits in the defeat. After 35 games in 1969, the Orioles were 23-12.

1970 (20-8): Third baseman Brooks Robinson and second baseman Chico Salmon hit back-to-back RBI singles in the bottom of the eighth inning to lift the Orioles to a 4-2 win over the White Sox in the second game of a doubleheader at Memorial Stadium, pushing the team to 21-8 through 29 games. The Orioles were 25-10 through 35 games that season.

1992 (19-9): White Sox first baseman Frank Thomas hit a solo home run in the top of the 10th inning off relief pitcher Gregg Olson at Camden Yards, dropping the Orioles to 19-10 after a 4-3 loss in their 29th contest of the year. The Orioles had a 24-11 record after 35 games in the first season in the new ballpark.

1997 (19-9): Right fielder Eric Davis was 4-for-4 with a solo home run, and the Orioles scored six times in the bottom of the seventh inning for a come-from-behind victory, 8-4, over the Anaheim Angels at Camden Yards. The Orioles, who improved to 20-9 with the win, were 24-11 after 35 games that season.

2005 (19-9): Bruce Chen improved his record to 4-1 after only giving up two unearned runs in seven innings as the Orioles beat the Royals, 5-3, at Camden Yards to improve to 20-9 after their 29th game. The Orioles were 22-13 after 35 games that season.
