After spending the first three or so weeks on the job holding meetings and getting acquainted with the team's player development and baseball operations staff, Preller shifted to meeting with many of the club's scouts, both to seek their input and to get to know them.
He's also physically visited three Minor League affiliates -- Class A Lake Elsinore, Double-A San Antonio and Triple-A El Paso. There's a chance he could see Class A Fort Wayne in the playoffs, he said.
Now, his attention is mostly fixated on watching how the big league club performs over the final 25 regular-season games, as a whole and individually.
"From the big league side, continue to see the guys come out and play with energy and compete and play winning baseball," Preller said. "That's the biggest thing. I think a lot of the guys have played well for the last few weeks, the last month, you'd like to see them finish that out and finish the second half strong."
The Padres entered Wednesday's game with a 66-71 record having gone 18-11 since the start of August with a roster that could look far different by Opening Day 2015.
Preller said that he's curious to see how some of the new roster additions perform this month to see if they potentially fit into the team's plans in 2015 and beyond.
"Some of the newcomers, [see if] can they break in, be part of the club in the last month and set themselves up for next spring and get in a spot where they can compete to make the team," Preller said. "And for guys like Tyson Ross and Ian Kennedy, you want to see them finish strong."
