Both young starters are being mentioned as possible selections for the All-Star Game on July 16 at Citi Field in New York. The All-Star teams will be announced on Saturday.
"The coaches have a lot to do with it," Sveum said. "For what Wood has gone through from spring training last year and getting him to understand about his arm side command. For him being able to consistently do that and what (he has done with special coaching assistant) Mike Borzello with the game reports, never varying from it. (The coaching staff) all have a lot to do with it but the biggest thing is about the adjustments (Wood) has made."
Chris Bosio, in his second season as Cubs pitching coach, takes some pride in the growth of both young starters.
"They both are deserving of strong consideration," Bosio said. "Both have pitched well and both have been on some tough ends of no-decisions. They have lowered their walks per game since last year. I think these pitchers have performed like All-Stars. It would not surprise me if either one made it although the competition is steep in our league."
The numbers support both pitchers' cases. Samardzija, who is 5-7 with a 3.36 ERA and 1.20 WHIP, has been among the leaders in innings pitched and strikeouts all season. Wood, who is 5-6 with a 2.69 ERA and a 0.98 WHIP, has 16 quality starts in 17 outings, the most in the major leagues.
As a team the Cubs have 52 quality starts and have a 25-10 record with 17 no-decisions.
