Not only have they been unable to earn the sweep, they have been blown out in three of four of those series finales. In contests in which they could earn a sweep, Baltimore has suffered losses of 11-2, 11-3, 19-6 and 8-5.
The Orioles will be in the same position Wednesday as they go for their first three-game sweep of the year against the Toronto Blue Jays.
Earning the sweep won't be easy, however, especially with Toronto ace Roy Halladay set to try for his ninth win of the season. Halladay leads the Majors with eight wins this season, and he has thrown 75 innings, recording a 2.52 ERA.
Halladay faced the Orioles just once this season, throwing eight innings and striking out six in an 8-4 win on May 1.
"I think he's the best pitcher in baseball," third baseman Melvin Mora said. "He knows how to get the lefties out, which is hard for a right-handed pitcher, so when you go out there and face a guy like him, you have to take your hat off and battle with him."
Arguably the Orioles' strongest weapon will be their recent offensive consistency.
The Orioles have scored in seven different innings over the first two games in the series, including putting up seven runs on 14 hits in the victory Tuesday.
As for the reason? Well, it's simple.
"Guys are getting good pitches, and we're not swinging at the bad ones," outfielder Nick Markakis said. "When you get those good ones, you start driving the ball, and it's a good thing to see. We won the series, so we're going to come out and try to win the last one today."Pitching matchup
BAL: LHP Rich Hill (1-0, 3.18 ERA)
Hill provided another solid outing in his second start of the season, proving that he's over the sore left elbow that delayed the start of his season. The lefty made just one mistake -- a two-run home run by Ryan Zimmerman -- and left in the midst of a sixth-inning jam. The Orioles will keep sending the southpaw out there every fifth day, and his presence means even more after the release of Adam Eaton. TOR: RHP Roy Halladay (8-1, 2.52 ERA)
Halladay took a no-decision against the Braves on Friday, ending a remarkable run of 26 consecutive starts with a decision. Over that streak, which dated back to last June 30, Halladay went 20-6 with a 2.57 ERA and five complete games. Against Atlanta, Doc logged seven shutout innings, scattering five hits with six strikeouts and one walk. Over his past six turns, Halladay has gone 5-0 with a 1.76 ERA, compiling 37 strikeouts and just six walks over 46 innings. He has lowered his ERA in each of his past five starts and has turned in at least seven innings in each of his 10 outings this season. In his career against the Orioles, Halladay has gone 19-4 with a 2.88 ERA. Tidbits
