Houston manager Dusty Baker announced early on Friday a contingency plan for his weekend rotation, with right-hander Chase De Jong in line to start Saturday in the event the Astros clinched a postseason berth on Friday night against the Texas Rangers at Globe Life Field.

The Astros (29-29) failed in their bid to secure the final American League postseason bid on their own accord, falling 5-4 in 10 innings after closer Ryan Pressly surrendered a game-tying solo homer to Rangers first baseman Ronald Guzman with two outs and two strikes in the ninth.

"We were so close to clinching it," Baker said. "He (retired) the first two hitters and was 0-2 (on Guzman) ... sheesh, that hurts. There's nothing we can do now. We've got to come back (Saturday) and play hard."
