The Chicgo Cubs have determined they aren’t going to get the required blockbuster package for righty Jeff Samardzija, writes Jon Heyman of CBS Sports, so they’ll make a third attempt to extend him this winter. Should that fail, “a trade will become much more likely.”

Samardzija, 28, has a 3.75 ERA, 9.1 K/9, 3.4 BB/9, 0.94 HR/9, and 48.5% groundball rate in 144 innings this year. Those are solid numbers, and he has the repertoire of an ace, but so far Samardzija’s control hasn’t taken a leap forward as it appeared earlier this season (in fact, it’s been worse than last year). The Cubs control Samardzija for two more years after 2013.
