• Instead of adding another outfielder, the Cubs activated reliever Shawn Camp from the disabled list Saturday, which leaves them a little short-handed as far as position players go.
Sveum said there would be no change in the immediate future.
"Right now, it's coming in handy having that extra guy," Sveum said.
• Alfonso Soriano was visibly upset after Sunday's loss to the Mets in which Marmol blew a three-run lead in the ninth.
"For the position players in that clubhouse as well as some of our starting pitchers, a lot of our starting pitchers, it's been frustrating to beat a lot of teams and have games won after seven innings -- whatever our record is after the seventh inning -- and have a run differential of where we are," Sveum said. "It wears on you after a while as a player."
The Cubs have 21 losses in games in which they have had a lead.
• Left-handed pitcher Rob Zastryzny, the Cubs' second-round pick in the First-Year Player Draft, has apparently signed with the team. Zastryzny tweeted Monday: "Officially part of the Chicago Cubs organization. Thanks for all the support and I can't wait to start the journey. #Cubs"
The Cubs have yet to confirm any Draft signings.
