Here are some of the statistical storylines the broadcast crew of Jon Sciambi, Aaron Boone and Mark Mulder likely will be talking about starting at 7 p.m. ET on ESPN2.
The Orioles had the fourth-youngest Opening Day roster in baseball, with an average age of 28 years, 136 days, whereas the Yankees had the fifth-oldest at 30 years, 31 days. The Texas Rangers had the youngest roster (27 years, 333 days), and the San Francisco Giants had the oldest at 31 years, 100 days.
Yankees lack offensive punch
The Yankees are hitting .233 as a team through their first six games, their lowest batting average through six games since they hit .220 in 2004.
This year’s start follows two seasons of notably weak offense from the Yankees. In 2014, they had their fewest runs (633) and walks (452) and their lowest on-base percentage (.307) since the 1990 season, when they were 67-95. Their .414 win percentage in 1990 is the fourth-worst in team history and the team’s worst in the live ball era.
Looking at American League rankings the last two seasons, the Yankees are 11th in home runs, 12th in runs per game and OBP, 13th in batting and 14th in slugging percentage.
The Yankees have the last two postseasons, the first time they’ve missed consecutive postseasons since they missed the playoffs from 1982 to 1993.
Pineda contributes in limited action
Michael Pineda (0-0) is scheduled to make his second start of the season. He was traded to the Yankees in January 2012 by the Seattle Mariners. Pineda had just finished his rookie season with the Mariners at age 22 and was ninth on Keith Law’s preseason top 100 prospects lists entering 2012.
A shoulder injury in 2012 prevented him from making his debut for the Yankees until 2014. Despite missing three months with a different shoulder injury, he was one of the team’s most valuable pitchers last season. His wins above replacement (2.7) ranked third among Yankees pitchers last season.
Pineda made two starts against the Orioles last season, and he did his best work against them. He allowed one run in 12 innings, had a 12-1 strikeout-to-walk ratio and induced a miss percentage of 27.3 percent.
Orioles are chasers
In the Orioles, Pineda will face a team that expanded the strike zone like few others in 2013 and 2014.
Over the last two seasons, the Orioles had a chase percentage of 30.1 percent, fourth in the major leagues. The Colorado Rockies had the highest chase percentage during the last two seasons, 31.5 percent.
The Orioles last season won their first division championship since 1997 and are seeking to win consecutive division titles for the first time since 1973-74.
But the Orioles were swept in the ALCS last season by the Kansas City Royals, becoming the fifth team to be swept in the ALCS since it moved to a best-of-seven format in 1985. Each of the previous four teams missed the postseason the next year.
Orioles dig the long ball
Last season, 47.8 percent of the Orioles’ runs came via the home run, the third-highest of any team in the last five seasons.
Since the start of 2011, no team in baseball has hit more home runs than the Orioles (839), and the gap between first and second (Yankees, 767) is wider than the gap between second and fifth (Brewers, 697).
