"With more experience, you learn to handle the adversity better, and you learn to have a different perspective when it comes to takeaways from at-bats," Jackson said. "In years past, I certainly put a little more weight on what the result was at the end of the day and what my numbers were at the end of spring, [instead of] 'how am I feeling, how am I improving because of this at-bat.'"
Jackson started the spring 1-for-11 before his two hits in the late innings on Saturday. But he also had four walks -- which he believes are indicative of how well he is seeing the ball.
"A lot of what plate appearances are in Spring Training are to iron out timing, to see the ball better and to work on your approach," Jackson said. "It's not always about the results. There's something to take away from a strikeout, there's something to take away from a hit, there's something to take away from a walk. I think I've been very productive with the way I've looked at at-bats."
Jackson, the Cubs' first-round pick in 2009, is hopeful to earn a spot on the big league roster coming out of camp, but he understands there's only so much he can control.
"Personally, I'm preparing myself for every opportunity that's presented," Jackson said. "Yesterday I got the opportunity."
