The pitching staff was again at the forefront, with four Terps combining to allow just one earned run in the two games combined.
David Carroll (2-0) pitched a complete-game two-hitter in game one, while Sander Beck (1-0), Charlie Haslup and Will Bouey held Manhattan (1-6) to just one run in game two.
Only twice since 1924 have the Terps had a better start than this season: in 1967 they opened 12-1 and in 1968 they were 10-1.
Through nine games, Maryland has now held its opponents to a run or less on seven occasions. Manhattan came into the series hitting .331 as a team, but has gone just 11-for-78 (.141) in three games against the Terrapins.
Carroll set the tone, holding the Jaspers without a hit over the final four innings in the 7-inning game one victory. The senior struck out six, retired the side in order in the fourth, fifth and sixth innings, and threw just 85 pitches in the complete game.
Manhattan scored an unearned run in the first inning, but Maryland knotted it at 1-1 in the second when K.J. Hockadays triple to right field drove in Michael Montville. Alfredo Rodriguez followed with a single through the left side to plate Hockaday, and after Rodriguez stole second and third, Jordan Hagel drove him in with a single to left-center field for a 3-1 Terrapin advantage.
The Terps added another run in the fourth without a hit, using three hit batsmen and a walk to force in the games final run. That was more than enough for Carroll, who gave Maryland its first 7-inning complete game since April 21, 1999.
In game two, Hagel gave Maryland an early lead it wouldnt relinquish with a two-run homer in the first inning. The junior went 4-for-5 with three runs and three RBIs in the game.
Beck, meanwhile, was in control after allowing a run in the second. In his first start of the season, the senior allowed just one hit after the second inning before exiting after five. Haslup then allowed just one hit in two innings and Bouey, a freshman making his Maryland debut, pitched two perfect innings with a pair of strikeouts.
Maryland scored a single run in the third and put the game out of reach in the fourth with four more runs. Hagel and Tim Kiene both had RBI doubles as part of the rally.
The Terps go for the four-game sweep Sunday at 1 p.m. RHP Brett Harman (1-0, 0.00) will take on Manhattan RHP Mike Giordano (0-0, 1.50).
