Colorado finished 1-5 on the trip to Arizona and San Francisco, but in the five games he played, Iannetta hit .412 (7-for-17) with a home run, two RBIs and a pair of walks.
Moved one spot higher to the No. 7 hole in the lineup Sunday, Iannetta notched a pair of singles, his second two-hit game of the road trip. His batting average, now at .230, has jumped 55 points since May 1.
"I've felt comfortable the entire time. A lot of it was just figuring out how aggressive I needed to be in the eight-hole," said Iannetta, who hit seventh in the lineup for Monday's series opener against the Mets. "Once I started getting that under control, things started slowing down a little bit."
Iannetta has made several mechanical adjustments at the plate. He has focused on moving his hands into position during his startup. The result has been a softer landing of the front foot, which allows Iannetta to better cover the strike zone.
"When he's doing that and he's separating, he's behind the ball and he's in a real good position to hit," Rockies manager Jim Tracy said. "That's why you've seen him be more successful here as of late than he was in the earlier part of the season."
