It's hard to say whether the Pirates will be buyers or sellers at the trade deadline this year. They came close to getting back to .500 last night, before the bullpen fell apart late in the game. That's almost a microcosm of their season, as they've been a streaky team in either direction, getting off to a great start, then seeing a big drop recently that led to them going below .500 for the first time this season.
They've also been an organization that hasn't had a clear direction at the trade deadline in recent years, both buying and selling at the last two trade deadlines when they were on the fringe of contending.
