"I've started to keep more of that stuff as I get older. You never know how much longer you're going to get to play. So that's kind of cool for the kids to hang on to or whatever you want to do with them."
At 33 and coming off winning last year's National League batting title, Morneau doesn't look anywhere near the end. He went 1-for-13 with a double in the Rockies' three-game, season-opening sweep at Milwaukee, but his approach was solid and his outs were increasingly hard.
"He lined out about four times in that series, and [on Friday] comes off the bench and hits the ball opposite field," Rockies manager Walt Weiss said.
Wilin Rosario started at first base against Cubs lefty Travis Wood. Weiss went to Morneau against Friday callup Brian Schlitter -- against whom Morneau was 2-for-2 with a double. He added a homer to the left-field gap on an 0-1 fastball, which gave the Rockies a 4-1 lead.
"He's one of those guys I'd seen," Morneau said. "Sometimes when you pinch-hit or come in like that, late in the game, it's sometimes better. You go up there with a simple approach. You don't really have enough time for your mind to get in the way."
