Anthony Rizzo felt better the day after a first-base collision that the Cubs know could have been so much worse.

Rizzo joked that he felt like a gymnast after going airborne and tumbling up the first-base line on Tuesday night at Minute Maid Park. Houston's Brett Wallace jumped into Rizzo trying to catch a high throw, and manager Dale Sveum said the Cubs have ruled out any head or leg injuries from the fall.

Rizzo took some swings in the cage on Wednesday and could be available to pinch-hit against the Astros – and back in the lineup by Friday. The same goes for outfielder Brett Jackson, who's been sidelined with a bruised right knee since running into the wall and making a highlight-reel catch last week in Pittsburgh.
