Jordan Westburg hit a three-run homer among four hits with a career-best five RBIs and Dean Kremer pitched seven sharp innings to give the Baltimore Orioles a 12-0 win over the Houston Astros on Sunday.

Kremer (9-9) allowed just three singles and struck out seven. Grant Wolfram and Corbin Martin finished the six-hitter.

The Astros were shut out for the second time this series after Brandon Young came within four outs of a perfect game in Baltimore’s 7-0 win Friday night.

Westburg hit an opposite-field shot to right-center off Shawn Dubin in the fifth to make it 5-0. He added RBI singles in the seventh and eighth. His four hits matched a career high.

Houston starter Cristian Javier (1-1) left with an illness after allowing one run in three innings. The Astros used five relievers before outfielder Chas McCormick threw a scoreless ninth in his second pitching appearance this week.

The bases were loaded in the third when Jesús Sánchez robbed Gunnar Henderson of a grand slam with a leaping catch into the seats in right field. Jeremiah Jackson scored on the sacrifice fly to make it 1-0.

Sánchez robbed another homer in the seventh with two on when he reached into the seats to snag a fly ball hit by Samuel Basallo, who was making his major league debut. Basallo, the Orioles’ top prospect, drove in two runs with a single in Baltimore’s five-run eighth.

Key moment

There was a brief delay in the top of the eighth when a fan jumped onto the field and ran around before being tackled by security, handcuffed and escorted off the field.

Key stat

Dubin has allowed 11 hits and 11 runs over 2 2/3 innings in his last three appearances.
