Every time Daniel Nava starts at first base, he is presented with a fresh learning opportunity, each ending with him feeling more comfortable and confident than the last.
Nava didn’t play the position as a professional until spring training this year. On Sunday night against the Yankees, Nava made his seventh start at first base, and 15th appearance overall.
“I’m feeling more comfortable,” Nava said. “If I’ve been playing first every day of the season until now, I’d be like, ‘Yeah, I’m great.’ But since it’s been sporadic, the more I play, the more I would feel comfortable. I’m still far more comfortable than the very first spring training game, but I still know I have a ways to go in order to be where I’d like to be.” Full story for BostonGlobe.com subscribers.
