HOUSTON -- The Astros' lineup got two right-handed reinforcements back from injury on Friday against the A's in shortstop Ronny Cedeno and third baseman Matt Dominguez.
Cedeno has missed the last eight games -- mostly due to sinus issues that flared up when the team was in Pittsburgh last weekend. He hit ninth in the Houston order on Friday and started at shortstop in the Astros' 6-5 loss to the A's.
Cedeno said he lost weight and felt dizzy from the sinus problems. Houston manager Bo Porter said the 30-year-old also experienced some vomiting.
"I was extremely anxious to get him back," Porter said. "When you're dehydrated and dizzy, that can stay with you for a few days, even after the medicine and treatment wears off. So I wanted to see Ronny move around and be 100 percent for a few days before we brought him back."
The Astros exclusively faced right-handed starting pitchers against the Royals, and Cedeno is hitting just .103 against righties this season. He had a healthy .464 average off southpaws entering Friday.
Cedeno went 1-for-3 in the loss, lining a hit off A's starter Tommy Milone to continue a two-out rally in the fifth inning and later scoring on a Jose Altuve single.
Dominguez missed Wednesday's 3-1 win against Kansas City with a sore left quadriceps, but Porter said the third baseman could have played, if necessary.
"It was a planned two days rest," Porter said. "We gave him that day, because we had Thursday off and wanted to help him heal faster, give him a game to regroup and recover. He's healthy and ready to go."
Dominguez hit a solo home run Friday to ignite a five-run fifth inning and now has five home runs in his last 11 games.
"I'll just keep getting treatment and it's something I can keep playing through and it's not a big deal," he said. "It's just tight. It might not go away right away, but I'll continue treatment and eventually it will go away."
