The Pirates are being patient with right fielder Gregory Polanco, who has struggled in his second season in the big leagues. He's currently in a 7 for 57 slump that has him batting .234 heading into today's series opener with Detroit.

PITTSBURGH (AP) — A year ago, Gregory Polanco was the next big thing. When the Pittsburgh Pirates outfielder was called up to the big leagues last June, his arrival was viewed as a coronation.

On a team desperate for power, the impossibly raw kid with the seemingly effortless swing appeared to be the jolt the Pirates needed.

After an initial splash, Polanco plateaued and then plunged. The same player who hit .288 in his first month as a major leaguer last June is in the midst of a 7 for 57 dip that has him batting just .234 heading into Tuesday’s game at Detroit.

“I knew it was going to be hard,” Polanco said. “I know I just have to keep working, keep grinding, keep learning.”

The lessons are coming at a furious pace for the whole world to see. While Pittsburgh sent Polanco briefly back to Triple-A Indianapolis last August, there are no plans for another stint in the minors, at least not yet.

“We still fully see the good guy that he can become,” general manager Neal Huntington said. “He’s battling through it. He’s staying strong mentally, which is really encouraging. He still shows flashes of it, which is really encouraging. Now it’s about maturing and being able to do that on a consistent basis.”

Even Huntington acknowledges Polanco may have been “rushed” to the majors last summer, an emergency call-up when Neil Walker was hit by appendicitis. Things came so easily during those heady first few weeks, then expectations rose. Now they’re nowhere close to being met.

As he enters his second calendar year in the majors, every step forward is met with a step back. For every leaping grab, there’s a ragged route to the ball that turns opposing outs into hits. For every stolen base, an instance when his baseball IQ proves very much a work in progress.

Last Friday against Atlanta, Polanco was on first when Chris Stewart hit a ball deep into the hole at shortstop. Andrelton Simmons’ throw to first was late. Polanco turned around second and kept chugging to third. One problem: teammate Jordy Mercer was already there, holding up when the ball didn’t leave the infield. Polanco was tagged out in a rundown to end the inning. The Pirates pulled it out in 10 innings, but Hurdle saw another teachable moment.

“We don’t stick our head in the sand,” Hurdle said. “Winning can be a deodorant. I’ve been in situations where things are overlooked when you win, and then they’re overcooked when you don’t. Not so here.”

Polanco’s confidence remains intact. Ask him if he feels more like a big leaguer now than he did during his blistering start as a rookie and the polite, soft-spoken Dominican nods.

“I feel like I can play here,” he said.

So do the Pirates, who continue to give Polanco opportunities to hit his way out of his latest slump even though they have other options.

“I do see growth,” Hurdle said. “I love the layer of toughness he’s going to have to add to get through this, the mental and the physical.”

Part of Polanco’s problem is the adjustment pitchers have made now that there is ample tape on his lengthy lefty swing. He’s consistently falling behind in counts. Those jabs too often turn into groundballs. That’s not what Polanco or the Pirates had in mind for a player with the tools to be a gap-to-gap hitter with an occasional homer mixed in.

“You see some really good swings and you see some swings that look predetermined, that look anxious, that look like a guy that is trying to get seven hits in one at bat,” Huntington said. “I hope he feels the support we have for him as an organization. We also have expectations.”
