 Christian Walker swings and misses at a slider. One and two. He picked a great day to come to the ballpark just as a fan. It is a glorious afternoon here on the north side of Chicago. Sunny, 76 degrees. Not a cloud in the sky. A light breeze blowing from right to left. The pitch. Walker fouls it back off the screen. Count remains one and two. Johnny Vincent. So Johnny and I grew up in the same neighborhood in Chicago.
