The Pirates will have a decision to make later this month on whether they will be buyers or sellers at the trade deadline. They are currently eight games under .500, and ten games back from the Wild Card race, with a lot of teams in front of them. So it makes sense to sell, and to give time to the younger players the rest of the season after they sell.
If the Pirates are going to get back to winning, they can't entirely rely on internal options. They're going to need some outside help. But right now they have too many holes to focus on outside help at specific positions, and as a small market team, they can't bring in outside help to patch all of those holes.
