HOUSTON (Interstat) — Peter Lambert pitched seven shutout innings and Braden Shewmake and Christian Walker each homered as the Houston Astros defeated the Los Angeles Dodgers 2-1 on Tuesday night at Daikin Park before a crowd of 37,008.

The game, which lasted 2 hours, 15 minutes, gave the Astros their second win in three games and improved their record to 15-22. The Dodgers, who had won the series opener 8-3 on Monday, fell to 22-14.

Lambert allowed only three hits, struck out four and walked none in his second consecutive strong outing. After taking a loss at Baltimore on April 30 in which he gave up two runs in 4 1/3 innings, the right-hander threw six scoreless innings in a win at Cleveland on April 22. On Tuesday, he retired the first eight batters before Andy Pages singled in the second inning, and he never allowed a runner past second base until the eighth.

Shohei Ohtani, the Dodgers starter, matched Lambert with seven innings of his own, allowing four hits and two runs while striking out eight. Ohtani did not walk a batter but surrendered solo home runs to Walker in the second inning and Shewmake in the third.

Walker’s homer, his ninth of the season, came on a fly ball to left field with one out in the bottom of the second and tied the game 1-1. Shewmake’s homer, his second, went to left with one out in the third and gave the Astros a 2-1 lead.

The Dodgers’ only run came in the eighth inning. Pinch-hitter Alex Call led off with a double to left field off Bryan King, who had taken over for Lambert. After Freddie Freeman struck out and Will Smith flied out, Kyle Tucker singled sharply to right field, scoring Call. Tucker was stranded when Teoscar Hernandez grounded out.

King then retired the Dodgers in order in the ninth, striking out Santiago Espinal and getting Miguel Rojas on a popup to first base to earn his third save of the season.

The Dodgers outhit the Astros 6-4, with Pages collecting three singles and Tucker driving in the only run. Freeman doubled in the first inning but was left on base. The Dodgers had opportunities in the fourth when Pages and Alex Freeland walked to load the bases with two outs, but Rojas grounded into a forceout. They also put two runners on in the second, but Rojas lined out to end the inning.

The Astros’ defense turned a key double play in the seventh inning. With one out and Freeland on first after a walk, Rojas grounded to second baseman Jose Altuve, who started a 4-6-3 double play to end the inning.

Lambert retired the side in order in the first, third, fifth and sixth innings. He worked around a leadoff single in the second and a leadoff double in the eighth, when he was replaced after Call’s double.

Ohtani struck out the side in the first inning and fanned at least one batter in each of the first six innings. He allowed a single to Nick Allen in the fifth and a single to Shewmake in the same inning, but Altuve struck out to end that threat. Ohtani departed after throwing 98 pitches.

The Astros, who had lost six of their previous seven games, bounced back after Monday’s defeat. The Dodgers were coming off a 4-1 win at St. Louis on Sunday and had won five of their previous six games before Tuesday.

The two teams wrap up their two-game series Wednesday night at Daikin Park. The Dodgers then return home to host the Atlanta Braves for a three-game series starting Friday, followed by four games against the San Francisco Giants. The Astros travel to Cincinnati for a three-game set beginning Friday, then return home to host the Seattle Mariners for four games and the Texas Rangers for three.
