Brewers beat-writer Adam McCalvy reported today that Chris Narveson will be working out of the bullpen temporarily because of two scheduled off-days over the next five games. But is this really temporary?
It has been well-documented that the Milwaukee Brewers lack a lefty reliever out of the bullpen and have been linked to numerous potential waiver-wire trades that could fill that void. However, with Narveson in the pen, it may not be necessary to make that trade. So how would the Brewers manage the last month of the season with only four starters?
September call-ups are just around the corner. The Brewers will likely not expand their roster extensively given their recent success—they hold a 10-game lead over the Cardinals in the NL Central.
However, Wily Peralta, Milwaukee's top pitching prospect, was recently promoted to AAA-Nashville and has been absolutely dominant. Through his first three starts, he holds a 2-0 record with a 1.80 ERA and 24 strikeouts.
Furthermore, Ron Roenicke is already relatively familiar with Peralta's talents. He was a candidate to replace Greinke early on in the season while recovering from a broken rib. While it may be a risk to give starts to a rookie during a pennant race, Peralta could prove to be an upgrade over Narveson in the rotation, and the Brewers would have a lefty relief option out of the bullpen without having to make a trade.
Over the next several games, I suspect Doug Melvin and Ron Roenicke will be paying close attention to how Narveson pitches out of the pen, and if Wily Peralta will continue to miss bats in the minors.
