The Cubs have started discussing a two-year contract extension with John Grabow, according to ESPN.com's Bruce Levine. The lefty, who is scheduled to hit free agency after the season, would be a setup man to Carlos Marmol and occasional closer in the Chicago 'pen.
Grabow has allowed just 55 hits in 66 innings this year with the Pirates and Cubs. He has 53 strikeouts, but has walked 39 along the way. If the extensions to Trever Miller and Ryan Franklin are any indication of the market for relievers, Grabow, who made $2.3MM this year, could be in line for about $4MM over the course of the next two years.
