The Rangers drafted Glen Cook in the 24th round of the 1981 draft. By 1985 he had made the Major Leagues with a nine game stint late that year. In 1986 he would be back with Oklahoma City, just as he is pictured on card number 146 of the 1987 ProCards set.
Glen spent the entire 1987 season at Triple A. He would appear in 31 games. All of his appearances would be in relief and he would toss a total of 57 innings. He ended the season with a 4.53 ERA and a 1.335 WHIP. That in spite of striking out 36 while walking 23.
1987 would be the end of the line for Glen. After seven seasons in the Rangers' system and only one stint in the Bigs he hung up the spikes.
