BALTIMORE — Samuel Basallo hit an RBI single in the 11th inning that was initially ruled a foul ball to give the Baltimore Orioles a 3-2 walk-off win over the Pittsburgh Pirates on Tuesday night.

Basallo’s popup to left grazed off the glove of left fielder Tommy Pham, landed on the chalk in the outfield grass, and was ruled foul. After a review, it was ruled a hit to drive in Gunnar Henderson for the Orioles’ third straight walk-off win.

Dietrich Enns (3-2) threw two innings with no hits and one strikeout in extra innings. Kyle Bradish struck out six, allowing four hits and one run in his third start since returning from Tommy John surgery on Aug. 26.

Jeremiah Jackson gave the Orioles a 2-1 lead with a solo homer in the sixth, but Pham hit a solo homer in the top of the ninth to make it 2-all.

Jackson was 2 for 3 for his 10th multihit game since making his MLB debut on Aug. 1.

Jackson Holliday also had two hits, scoring the first Orioles run in the first inning.

Dauri Moreta (1-1) surrendered two hits and a walk in the 11th, and allowed the walk-off hit. Pirates starter Mike Burrows threw four innings with two hits, one run, and six strikeouts.

The Orioles are 6-1 in September, and improved to 20-54 when their opponent scores first.

Key stat
