Toolsy Pirates outfield prospect Gregory Polanco ought to be the next top prospect to win a promotion, MLB.com's Jim Callis writes. MLB.com ranked Polanco the No. 13 prospect in baseball heading into the season, and he's done nothing to diminish his reputation since then, hitting .439/.475/.667 in 61 plate appearances so far for Triple-A Indianapolis. "He's done a little bit of everything," says Pirates assistant GM Kyle Stark. "It's been fun to watch. The exciting thing about him is he's extremely driven and has very good feel for making adjustments, so it allows him to keep getting better." Here are more notes from around the National League.
- MLB.com's Jonathan Mayo, meanwhile, argues for Archie Bradley of the Diamondbacks to be the next top prospect to reach the big leagues. Bradley, who raced through the Class A+ and Double-A levels last season, has a 3.31 ERA with 12 strikeouts and six walks in 16 1/3 innings for Triple-A Reno. Mayo suggests that it's not impossible that Bradley's impact on the Diamondbacks could be similar to Jose Fernandez's impact on the Marlins last year.
- With Ike Davis heading to the Pirates veteran Bobby Abreu could be making his way back to the big leagues with the Mets, Tim Rohan of the New York Times writes. In March, the Mets signed Abreu to a minor-league deal, suggesting to him that they might promote him to serve as a lefty pinch-hitter once they figured out what they would do with Davis and Lucas Duda. For now, Abreu is hitting .412/.487/.529 in his first 39 plate appearances for Triple-A Las Vegas.
