Nick Johnson, the Yanks’ own version of Mr. Glass, became the first casualty of Spring Training last week when his back tightened after he caught his cleat on the turf in the batting cage. While many in the media were up in the arms over the Yanks’ reliance on the fragile lefty, Nick and the Yanks insisted he was fine. The team opted to take it slowly so that the DH would be feeling strong, and he probably could have played had it been the regular season. This morning, we learn via Joe Auriemma that Nick took 50 swings in cage, is feelin’ good just like he knew he would and plans to play Monday. And exhale.
