Flores delivered on some of his promise this season as he shifted to third base. The 21-year-old mastered the Florida State League to earn a promotion to Double-A Binghamton in the second half. He batted a composite .300/.349/.479 in 493 at-bats and established career highs for homers (18), slugging, OPS (.827) and walks (38).
Best Pitcher: Righthander Zack Wheeler joined the organization last July as the prized prospect acquired from the Giants for Carlos Beltran, and the 22-year-old lived up to his billing by dominating at Double-A and reaching Triple-A Buffalo in August. Between the two stops he struck out 148 and walked 59 in 149 innings and went 12-8, 3.26 in 25 starts.
Wheeler ranked as the No. 10 prospect in the game at midseason, and at times he toyed with Eastern League hitters, wielding a fastball that touches the upper 90s and a wipeout slider. He indicated an improved feel for his changeup during the summer.
Keep An Eye On: Team officials raved about 21-year-old righthander Rafael Montero's propensity for throwing strikes all season long. And why not? He mastered the two Class A levels, going 11-5, 2.36 in 20 starts with 110 strikeouts and just 19 walks in 122 innings. He notched a 5-to-1 strikeout-to-walk ratio with St. Lucie.
Montero commands a low-90s fastball with a breaking ball and changeup that showed improvement this season, team officials said. Because of his lean, 6-foot stature, many believe he may wind up in the bullpen down the road, but he's a member of a group of Mets pop-up pitching prospects, such as righthanders Jake DeGrom, Cory Mazzoni, Domingo Tapia and Gabriel Ynoa, who have helped improve the system's standing.
• The list of September callups included the following prospects from Triple-A: second baseman Jordany Valdespin, third baseman Zach Lutz and righthanders Jeurys Familia, Collin McHugh, Jenrry Mejia and Elvin Ramirez.
• Center fielder Matt den Dekker batted .274/.321/.458 with 17 homers at the highest levels of the system but didn't earn a callup because the Mets did not yet want to add him to the 40-man roster.
