Cubs Notes: Feldman, Draft, Marmol, Stewart, Jackson

The Cubs are 12-20 on the season, good for the second-worst record in the National League.  On the plus side, four of their five starting pitchers have performed well, and the team has shown surprising power in the early going.  The latest on the North Siders:

• Scott Feldman is a name to keep in mind leading up to the trade deadline and in free agency after the season, writes ESPN's Buster Olney, after the 30-year-old pitched seven strong innings to defeat his former Rangers teammates last night.  Feldman has a 2.70 ERA through his first six starts, but should his peripheral stats remain steady, SIERA suggests something around 4.30 would be a better bet moving forward. 
• The Cubs have not missed a start from college righties Mark Appel or Jonathan Gray, but they have expanded their search beyond those two, GM Jed Hoyer told Jim Bowden on MLB Network Radio on Sirius XM yesterday.  The Cubs draft second overall next month, and despite Hoyer's lip service, they're widely expected to take Appel or Gray after the Astros pick.
• Asked by reporters why reliever Carlos Marmol continues to get chances, Hoyer instead offered that Marmol has been "ridden hard by a number of managers here" as an explanation for the former closer's struggles (via Jesse Rogers of ESPNChicago.com).  Given his $9.8MM guaranteed salary, the Cubs are presumably reluctant to release Marmol.
• Asked whether $52MM man Edwin Jackson is a candidate for the bullpen when Matt Garza returns, Hoyer ducked the question, noting that surplus starting pitching "always seems to take care of itself and we're a ways away from having to deal with that kind of issue."  Rogers feels that allowing Jackson to stay in the rotation due to his contract, at the expense of a better-performing starter, sends a poor message to the team.  I wonder, though, what kind of message would be sent to future free agents if the Cubs make a large four-year commitment to a pitcher and demote him to the bullpen after fewer than ten starts.  Regarding Hoyer's comment, the Cubs are really only two healthy weeks away from having to deal with the rotation surplus, as Garza should be ready to return after two more rehab starts.
• "An apparent lack of commitment" is behind Ian Stewart taking his allowed 72 hours to report to the Cubs' Triple-A Iowa team on his optional assignment, since Stewart had already been playing with the club on his rehab assignment, opines Rogers.  Stewart, earning $2MM this year, recently finished rehabbing a left quad injury.  UPDATE: Stewart did report back with Iowa yesterday, tweets Rogers.
• Padres third baseman Chase Headley "would be perfect for the Cubs," suggests Ken Rosenthal of FOX Sports.  The Cubs have three premium position player prospects in Javier Baez, Albert Almora, and Jorge Soler, and for me it's difficult to picture a Headley trade without one of them and equally difficult to imagine Hoyer and Theo Epstein parting with one during a non-contending season.
