HOUSTON — Ronel Blanco pitched seven strong innings and Chas McCormick homered twice to lead the Houston Astros to a 5-1 win over the Baltimore Orioles on Saturday.
Yordan Alvarez added a two-run shot to help Houston extend its winning streak to four games.
Blanco (8-2), who threw seven hitless innings in his last start, allowed four hits and a run with three strikeouts for his third straight win.
''He keeps doing it,'' manager Joe Espada said. ''I'm not surprised. Whenever we need a big start to pick our team up, he shows up and does what he's been doing all year.''
Alvarez put the Astros on top with his 16th homer, which came off Corbin Burnes (8-3) in the third, and McCormick made it 4-1 in the fifth. McCormick got his fifth career multihomer game when he connected again in the eighth.
The game was a relief for McCormick, who is hitting .225 this season and had just one homer entering Saturday's game.
''I needed a game like today,'' he said. ''It felt good. I've just been working hard and obviously I know I've been struggling, but I hope I can keep this momentum going forward.''
Burnes allowed five hits, including a season-high two homers and a season-most four runs in seven innings to snap his career-best streak of 10 consecutive quality starts. He was 5-0 in seven starts since a loss at Washington on May 7.
