Ryan Mountcastle came off the bench to go 2-for-2 with a two-run homer and Dean Kremer pitched 5 2/3 strong innings to lead the Baltimore Orioles to a 7-3 victory over the visiting Los Angeles Angels on Tuesday.

Mountcastle, who also doubled, pinch hit for designated hitter Ryan O'Hearn after the latter

hit a solo homer in his only at-bat of the game in the second inning. Jorge Mateo went 1-for-3 with two RBIs for the Orioles.

Kremer (5-1) allowed three runs on six hits with four strikeouts and no walks before turning it over to the bullpen, which allowed just two hits over the final 3 1/3 innings.

Matt Thaiss and Gio Urshela each had two hits and Mickey Moniak hit a solo home run for the Angels, who lost for the fifth time in their past seven games.

After Moniak delivered Kremer's fifth pitch of the game over the right-center-field fence to give the Angels a 1-0 lead, O'Hearn tied things up with his first homer of the season.

The Orioles, who snapped a two-game losing streak, took the lead for good with a three-run fourth inning.

Terrin Vavra's single to right scored Gunnar Henderson, who had doubled, for a 2-1 advantage. After Vavra took second on Chase Silseth's wild pitch, he crossed the plate on Mateo's single to right, knocking Silseth out of the game and bringing on reliever Tucker Davidson.

Mountcastle -- pinch-hitting for O'Hearn -- moved Mateo to third with a double to left before Mateo crossed the plate on Cedric Mullins' groundout.

Silseth (0-1) -- a reliever making his first start of the season -- allowed four runs on six hits with five strikeouts and a walk in 3 1/3 innings.

The Angels pulled to within 4-2 in the fifth when Zach Neto's single to center scored Urshela.

After Los Angeles trimmed the Orioles' advantage to 4-3 in the top of the sixth on Urshela's RBI single, the Orioles extended the lead to 7-3 in the bottom of the inning.

Mateo's sacrifice fly scored Adam Frazier, who was hit by a pitch and advanced to third on pinch hitter Ryan McKenna's double that deflected off Davidson and into left field.

Andrew Wantz relieved Davidson and gave up Mountcastle's two-run homer to make it 7-3.

Shohei Ohtani went 0-for-4 with a strikeout for Los Angeles a night after going 4-for-5 with a three-run homer, a triple, three runs and a walk in the Angels' 9-5 win on Monday.
