StreetJL, apparently doing some research for this week's Farmstros Five caught the fact that Leandro Cespedes started tonight for Round Rock. Sergio Perez was scheduled to be on the hill. The Express game notes indicate that Cespedes is just up for a spot start in Perez's place. Jordan Lyles is pitching tonight for Corpus, but the way he has been getting knocked around recently AAA might not be in his best interest at the moment. Doug Arguello is lined up to pitch tomorrow, so he would have been on short rest if he had been called up. My guess is that if Perez is out for more any more starts, a more permanent replacement will be brought up from Corpus Christi or brought in as a free agent signing.
NOTE: I got word from Larry Little with the Express that Cespedes is heading back to Lancaster Tuesday.
