When outfielder Scott Hairston arrived in the clubhouse at Tucson Electric Park this morning he was summoned to manager Bob Melvin’s office. This was an all too familiar trek for Hairston as he had made that same walk each of the three previous years during this week only to be told that he would not be making the trip with the Diamondbacks to Phoenix and he would be sent to the minors to work on some aspect of his game. That news would always be followed by a pep talk where he would be told how he should keep his head up and not let this news get him down. He was still a highly valued part of the organization and that with hard work he would be given a chance to make the team. Scott would be told that over the course of the season things happen and if he would stay prepared he could find himself playing for the Diamondbacks during the year. All those things are meant to put a young player’s mind at ease and minimize the disappointment they feel when they didn’t make the team. On paper it all sounds good but in practice it’s never easy. So it was understandable that Hairston was nervous making that familiar trip into the office where the door would be closed and news delivered. This year was different. Melvin didn’t greet him with a stern face but instead was all smiles. For the first time in his career Scott Hairston would begin the season on the opening day roster for a Major League baseball team.
