Cubs Notes: Guerrier, Arrieta, Strop, Offseason

Here's the latest from Wrigleyville….

• Matt Guerrier will be sidelined for the next 6-8 months after undergoing flexor mass surgery on his throwing arm today, MLB.com's Carrie Muskat reports.  Guerrier posted a 2.13 ERA in 12 2/3 IP for the Cubs after being acquired from the Dodgers in July.  The 35-year-old righty will be a free agent this winter and has said he would like to re-sign with the Cubs.  Given his injury situation, one would think Guerrier will be limited to a minor league deal this offseason.
• The Scott Feldman trade is looking like a win for the Cubs thus far, ESPN Chicago's Bruce Levine notes, as Jake Arrieta and Pedro Strop have both pitched well since coming to Chicago.  Arrieta allowed two hits over seven shutout innings in today's 7-0 Cubs win over the Cardinals, dropping Arrieta's ERA to 0.69 in two starts with his new club.  Strop, meanwhile, has a 2.41 ERA and 21 strikeouts in 18 2/3 innings as a Cub.
• In a live chat with Cubs fans, ESPN's Jesse Rogers predicts a relatively quiet winter for the Cubs, with "more turnover in pitching than anywhere else," though he doesn't think the Cubs will make a big splash for someone like David Price.  Rogers thinks outfielders Nate Schierholtz and David DeJesus will both stick with the team until at least the middle of next season
