Kent, the Astros’ homer run and RBI leader this season, left Thursday’s game in the fifth inning with a sore right quad.
His status for Friday’s game is unknown.
The Astros didn’t have any trouble completing the sweep of the Baltimore Orioles, posting an 11-1 victory. Houston, which went 5-7 against the American League last season, outscored the Orioles 28-11 in the series.
Ensberg, a part-time third baseman, went 3-for-4 to extend his hitting streak to seven games. He is batting .625 (10-for-16) with four homers and 12 RBIs.
The Devil Rays come in having lost two of three to the Cubs, including Thursday’s 8-1 decision.
Aubrey Huff drove in the lone run for Tampa Bay, which lost for the eighth time in its last 11. Huff finished 2-for-4, extending his hitting streak to seven games.
Rocco Baldelli, Tampa’s leading hitter, was given the day off.
Friday’s game will mark the return of Julio Lugo to Houston. The second baseman was released May 6 after being charged with misdemeanor assault on his wife. The Devil Rays signed him on May 15.
“I’m going to go there to play and whatever happens, happens,” said Lugo, who is batting .246 (16-for-65) with four RBIs for the Devil Rays. “I got along with the guys real well. It’s going to be hard to be on the visiting side.”
