He appeared in ten games during spring training where he walked three, struck out 13, and gave up three runs over 10⅔ innings. He was sent to Charlotte to start the season, and has struck out 11 and walked one batter without giving up a run in six innings.
Overall for his major league career, Putnam has appeared in 15 games for the Indians, Rockies, and Cubs over the past three seasons. Putnam's career ERA is 8.53 but with a more palatable FIP of 3.85. While only giving up one walk in the majors over 12⅔ innings, he's given up 22 hits.
Veal leaves the Sox after a second season of early control issues. He has walked seven and given up six hits over six innings this season. He has an ERA of 7.50 and a FIP of 5.06.
Adding Putnam and removing Veal keeps the 40-man roster steady at 39.
