Pittsburgh Pirates: Buyers

Why: At 54-36, the Pirates are nine games over .500 for the first time since 1992. The team is a game ahead of the Reds for the NL Central Division lead.

Who do they need: Earlier this season, the offense was on pace to be historically bad. It has improved a little, but its .299 wOBA is tied for 25th in the majors. 

The team could use help at shortstop, where Clint Barmes and Josh Harrison have been terrible. There’s not a huge market for middle infielders, so the team probably won’t get an impact player.

With the demotion of Jose Tabata, the Pirates could use some help in the outfield. They are expected to call up 23-year-out prospect Starling Marte, who should help. But left fielder Alex Presley has also struggled this season, so the team should still be looking for a corner outfielder. 

The team could also use help in the bullpen. Joel Hanranhan’s numbers look solid, but he’s struggled with his control this season. The Pirates 0.9 bullpen WAR puts ranks them 22nd in the majors.

Who can they deal: Pitcher Erik Bedard has been a big part of the Pirates' resurgence, but he’s always an injury concern. The team probably won’t part with him, but he can’t be counted on down the stretch. 

The Pirates really don’t have much else to offer. They can try and get rid of Rod Barajas or Casey McGehee, but there’s not going to be a big market for them. The team has some great, young prospects in the minors -- like Jameson Taillon and Gerrit Cole -- but shouldn’t trade them away for a shot at the playoffs this season.

Who is available: There’s not likely to be many middle infielders available, but the team could go after Marco Scutaro if the Rockies decide to sell. 

Carlos Quentin could be a nice upgrade in a corner outfield slot, but the Pirates will have a lot of competition for him. The Padres are also looking to sell Huston Street, who would be a nice addition to the bullpen.

Verdict: The Pirates are surprise contenders this season. While they should try and make a run for it, they need to be cautious not to give up too many assets.
