The Orioles will send their hottest pitcher – left-hander Brian Matusz – to the mound tonight with the opportunity to sweep the Red Sox at Fenway Park.

Yes, Matusz, who entered the season possessing the longest personal losing streak in baseball, seems to have things figured out of late.

Matusz (5-5), who is going for his fifth win in his past six starts, is 4-1 with a 2.78 ERA and he's coming off his best outing of the season, a season-high 7 1/3-inning start at Tampa Bay in which he allowed just two hits and one run while striking out seven. His outing Saturday was his longest in nearly 22 months, when he threw eight innings against the Rangers on Aug. 19, 2010.

The 25-year-old left-hander is also using his pitches effectively. Despite issuing three walks Saturday, he didn't labor deep into counts, allowing his 97 pitches get him into the eighth inning.
