Parkville's Patrick Elliott and Colin Fowble combined to pitch a three-hitter, and the Knights rapped 10 hits during a 10-3 victory over host Lansdowne Thursday.
Elliott, a senior right-hander, improved to 2-0 by striking out seven batters and allowing two hits and one earned run in five innings.
Parkville center-fielder Darien Williams was 2-for-3 with a double, and two RBIs. Teammate Ben Loundsbury, a catcher, had two RBIs and went 1-for-3.
Parkville (4-3) played close to mistake-free baseball. Knights coach Joe Mirable said that was the key to beating the Vikings.
"We didn't have a bad inning," Mirable said. "I was impressed. It always seems like we have that one shaky inning in every game that kills us. Today, we managed to limit the damage."
Lansdowne continued to struggle and suffered its third blowout loss in dropping to 1-3.
The Vikings committed four errors, which led to four unearned runs.
"We just can't seem to stop the problem with errors," Lansdowne coach Matt Kohel said. "That's the way the season has gone. In our losses, the errors have really hurt us. Instead of giving up one run, we give four or five."
Lansdowne's problems started in the top of the first inning as Parkville scored two runs on pitcher Jesse Tayman, who took the loss and gave up three runs (two earned) on four hits in three innings.
Williams led off with a single to center field and when he attempted to steal second base, catcher Brandon DaGrava's throw went into center field. David Miller misplayed the ball, which allowed Williams to score. Dariel Torres' bloop single to center scored Makani Samios-Uy to account for the other run.
The Vikings responded with a run in the bottom of the first to trim the lead to 2-1.
DaGrava and Joe D'Urso had back-to-back infield singles to start things off. After Mike Trietley struck out, Brian Voyce hit a grounder to shortstop Samios-Uy, who threw to Fowble for the out at second, but the relay throw was wide of first, which allowed D'Urso to score.
Parkville scored a run in the second on Williams' RBI double and pushed across two more in the fourth on Loundsbury's two-run single to make it 5-1.
The Vikings closed to 6-3 in the fifth when D'Urso scored on a wild pitch, but Parkville took advantage of some more Vikings' miscues in the sixth and added four runs.
Kohel watched Josh Janey come home on an error and Christopher Hoesch score on a wild pitch.
"We can't stop the bleeding," Kohel said of his team's mistakes.
