There will be many more sessions between the two. Marquis inked a three-year, $21 million deal on Dec. 19 and is hoping to regain the form of 2003 when he was 15-7 with a 3.71 ERA.
"I knew I wasn't too far off," Marquis said of his 2006 campaign. "I was trying to bottle up seven innings of work into one batter sometimes. Numbers don't always reflect the kind of pitcher you are, but you don't want to be known as the guy with the high ERA."
Marquis said he was just a hair off in his mechanics, and Rothschild helped tweak a few things.
"It was nothing more than to get my mind right," Marquis said. "It feels back to a natural movement, where I don't have to think about it much. That was where I was fighting to get back to the last three, four months of the season.
"I feel very positive about it, and I'm looking forward to picking up the ball again and throwing."
Cubs general manager Jim Hendry, who has spent close to $300 million on free agents this offseason, took some media and fan heat for spending $21 million on Marquis, but he said the money was justified.
"He was going to get $20 million-$21 million from three or four other different parties," Hendry said. "Certainly over a three-year look back, Jason's statistics and wins validate that type of a salary.
"He had a bad couple of months, and he'll be the first to admit it. But we feel he is capable of winning 14 or 15 a year, giving us some innings and lowering that ERA."
