OK this is getting a bit absurd. Kyle Gibson might have better stuff than Walters. He might be a bigger part of the future. He might be Superman in disguise but there were legitimate reasons to call up Walters instead. This was pointed out in another thread by Seth Stohs: Gibson's odd starts: 35.2IP, 4ER, 0.50ERA, 17H, 32K Gibson's even starts: 17IP, 17ER, 9.00ERA, 29H, 14K He was absolutely dominant in his odd starts but in his even starts he was dominated. The odd start Gibson screams, "promote me!!!" where as the even start Gibson screams, "I need help!!!". It is not unreasonable for the Twins to wait to see which Gibson is the real Gibson. On the other hand Walters had put together 6 straight starts with >6IP and a 2.06ERA. He had been pitching great.
