When the Rockies open Salt River Fields for workouts in two weeks, DJ LeMahieu will be there when the key turns in the lock. The Rockies’ vacancy sign at second base screams opportunity, and he’s determined not to miss a rep.

“I will be standing right there,” said LeMahieu, a Michigan native, who lives just 10 minutes from the Rockies’ spring training facility in Scottsdale, Ariz.

“To hear that a team really wants you is exciting. Colorado is a great place to play and hit.”

The Rockies’ winter isn’t over. They are still searching for infield help and continue to engage in trade talks with Atlanta for Martin Prado. Colorado has offered outfielder Seth Smith, who’s likely to be dealt before spring training, and an additional player, but the Braves haven’t budged. Smith drew interest from Seattle, but there is no fit, and the Rockies continue to talk with Oakland about a deal involving the outfielder.

Just 22, LeMahieu provides an intriguing infield option either as insurance or in a broader role. He was acquired on the final day of the winter meetings, the supporting actor in a trade of fallen prospects Ian Stewart and Tyler Colvin. LeMahieu is the type of player who grows on teammates: fundamentally sound and committed. He’s in the second-base mix that includes Chris Nelson and Jonathan Herrera.

“He’s real quiet, a no-nonsense guy who will work daily and do whatever it takes to win,” Cubs infielder Jeff Baker said Tuesday. “He gets it.”

LeMahieu doesn’t look the part of a second baseman, standing 6-foot-4 and weighing 205 pounds. If teamed with Troy Tulowitzki, the Rockies could turn double plays or play zone defense.

“I grew up as a shortstop, and I am getting comfortable at second,” LeMahieu said. “Obviously, Tulo is a bigger guy. He’s somebody I can really learn from.”

LeMahieu forged a reputation as a contact hitter in the minor leagues, batting .317 with a .353 on-base percentage in 1,132 at-bats. He hit .250 with the Cubs in a 37-game cameo last season.

“I have always prided myself on having a good average, and not striking out,” LeMahieu said. “I think by being a little more selective my power numbers will come and maybe a few of those doubles will start going out of the park.”

Footnote: The Rockies will use a new road jersey this season, expected to eschew pinstripes for solid gray.
