The sight of Anthony Rizzo lying motionless on the ground had to be unsettling. This is a player the Cubs have built their future around. Rizzo survived a nasty collision at first base on Tuesday night at Minute Maid Park, leaving a 1-0 loss to the Astros in the third inning with soreness around his right shoulder/upper back. Rizzo bounced a ball toward Houston second baseman Jimmy Paredes and ran hard down the line. Paredes made a high throw to first baseman Brett Wallace, who leaped and swept his left leg right toward Rizzo. The two players got tangled up as Rizzo – who's listed at 6-foot-3, 220 pounds and built like a linebacker – planted his left leg and flipped through the air almost to the edge of the outfield grass.
