Peña (knee), Correa (illness) out of Astros' lineup

SEATTLE -- Astros shortstop Jeremy Peña, who left Saturday’s game in the fourth inning with right posterior knee tightness, was out of the lineup for Sunday’s game against the Mariners, along with starting third baseman Carlos Correa, who’s still dealing with a lingering illness from last week in Colorado.

Astros manager Joe Espada said Peña was undergoing some imaging Sunday to determine the extent of the injury. Correa missed games against the Rockies on Tuesday and Wednesday with an illness but was in the lineup Friday and Saturday in Seattle.

Isaac Paredes started at third base on Sunday, with Nick Allen at shortstop.

Peña said following Saturday’s 8-7 loss that he felt the back of his knee tighten up while advancing from first to second base on a fly ball off the bat of Yordan Alvarez. He went to third on a single and was removed for a pinch-runner.

“It’s still a little bit tight,” Peña said. “But like I said, I don’t think it’s something too bad. Just stay on top of things and we’ll have a better understanding of what it is tomorrow after we get some imaging done.”

Peña admitted he felt the knee tightness “a little bit” during Friday’s series opener, but it went away.

“I didn’t tell anyone, which I probably should have,” he said. “I woke up today feeling pretty good and went into the game feeling really good, and then it tightened up on me. I think it’s best to stay on top of it.”

Coming off a career season, Peña is off to a slow start this year because of health. He fractured the ring finger on his right hand during an exhibition game while playing for the Dominican Republic’s World Baseball Classic team in March, which took him out of the tournament.

Peña began the season on the Astros’ active roster but didn’t begin starting every day at shortstop until a week ago. Peña went 1-for-3 on Saturday and is slashing .256/.304/.349 with no homers in 10 games this year. Correa is slashing .294/.368/.412 with one homer and nine RBIs.
