Earlier this week, the Pirates claimed left-handed reliever Buddy Boshers off waivers from the Houston Astros. If Boshers were to be called up right now, he would be the only left-hander the Pirates would have in the bullpen (I'm not counting Felipe Vazquez in this article, since he is only going to be used at the end of the game). They had Steven Brault in the big leagues, but he was sent down a few days earlier, leaving an all right-handed group.
The Pirates added a reliever at the trade deadline, but it was right-hander Keone Kela. That filled a need for another late inning reliever, but didn't add the big lefty that fans wanted.
