Snippets of what BA wrote on Puello (they mentioned the Biogenesis case but didn't go farther than one sentence): Just a few years ago, right fielder Cesar Puello stood as one of the organization’s brightest prospects at any position. His intriguing combination of physicality, speed and arm strength contributed to a No. 3 ranking among Mets farmhands entering the 2011 season. So while trouble turning his tools into production, managing the strike zone and staying healthy caused him to slide to the fringes of the prospect radar, the 22-year-old Puello has enjoyed a stunning resurgence at Double-A Binghamton this season, finally making good on the power potential that led to him being so highly touted. ------------- Puello advanced to Double-A to begin the 2013 season, and with his April performance he showed signs of improvement when compared with his previous two years. He hit .280/.357/.420 in 15 games—though he didn’t hit a home run—but then something seemed to click for Puello the following month. On May 3, he hit a home run off Harrisburg lefthander Ian Krol. He went three days before hitting another one off Trenton righthander Jose Ramirez. The day after that, Puello blasted two home runs off Trenton lefty Nik Turley. So began Puello’s prodigious hot streak. Since that first homer, he has hit .341/.404/.659 with 15 homers and 46 RBIs in 47 games. Puello had another two-homer game on June 6, again against the Thunder. As of July 2—six years to the day since he signed as an amateur—Puello leads the Eastern League with 15 home runs and a .602 slugging percentage. The homers haven’t been chip shots, either. One, hit off Altoona lefty Nate Baker, was drilled to dead center so hard that it was over the batter’s eye before the center fielder made it to the warning track. ------------------------------- New Approach, New Mechanics While Puello finally is tapping into the power that his sturdy frame affords him, those numbers don’t quite tell the whole story. His walk rate hasn’t dramatically increased this season, but according to his Binghamton coaches, Puello’s plate discipline, working in concert with mechanical adjustments and improvements, have keyed his resurgence. Binghamton manager Pedro Lopez said Puello has been more selective in terms of what he swings at and has refined his perception of the strike zone, picking pitches he can consistently drive rather than falling behind in the count and having to settle for less-desirable offerings. ‘The plate discipline, for me, it’s the No. 1 thing,†Lopez said. “In the past, he would get himself out . . . He would swing at way too many pitches over his head, down and away and stuff, and that didn’t allow him to get good pitches to hit. I mean, no pitcher would throw him a strike if he would keep swinging at those pitches.†But now that Puello has refined his idea of the strike zone and has cut down on helping pitchers out, his coaches have seen him drive both fastballs and offspeed pitches out of the park and into the gaps. Binghamton hitting coach Luis Natera said Puello has raised the pre-swing position of his hands this year to above his head, and the action of driving his hands down through the strike zone has helped Puello get more backspin on the ball and drive it farther. Natera also said Puello has made adjustments to draw more power from his lower half. “Power is the last thing to come,†Natera said. “You have to be a hitter first, and then you let it go. And right now, I think he’s a better hitter.†------------------------------- If Puello has a second half to match the first, then the Mets could have first-division-caliber corner outfielder on their hands. The man at the top, general manager Sandy Alderson, has taken notice. “He’s always been a five-tool guy, a five-tool projection, but not necessarily five-tool performer,†Alderson told Mike Francesca of New York’s WFAN on June 10. “This year he’s put it all together and has been phenomenal over the last couple of weeks.†Later
