SS Andres Gimenez (No. 55), 1B Peter Alonso (No. 58), OF Jarred Kelenic (No. 62), and RHP Justin Dunn (No. 89) all moved up on MLB.com's new Top 100 prospects list.
Gimenez was No. 60, Alonso No. 65. Kelenic No. 69, and Dunn No. 100 on the midseason list.
In the middle of the season, Baseball America's new farm system rankings had the Mets as the No. 19 overall system in baseball, up from No. 27 before the season.
During the season, the Mets' farm system got a boost from a breakout season from Alonso (Triple-A Las Vegas), a rebound season from Dunn (Double-A Binghamton), rapid advancement by Gimenez (Double-A), a return from injury by LHP Anthony Kay, and a strong campaign from LHP David Peterson.
In the lower levels of the minors, the team got strong production from 18-year-old SS/3B Mark Vientos and 17-year-old INF Ronny Mauricio.
The Mets also bolstered their system by selecting Kelenic No. 6 in June's Draft, and trading for RHP Franklyn Kilome (Double-A), RHP Bobby Wahl, and 3B Will Toffey.
But the cream of the system remains Gimenez, Alonso, Kelenic, and Dunn. Here's the gist on them, and when we can expect their Mets debut...
Andres Gimenez (ETA 2020)
The 19-year-old Gimenez excelled for High-A St. Lucie, hitting 282/.348/.432 with four triples, four homers, 20 doubles, and 28 stolen bases in 85 games before being promoted to Double-A Binghamton, where he was the second-youngest player in the league. Once there, he hit .277/.344/.358 with nine doubles, one triple, and 10 steals in 37 games.
"The way Gimenez moves his body, the rhythm, the timing and the feel for the barrel, didn't come overnight," Josh Norris wrote during the season for Baseball America. "It was forged over a decade and a half, since he was a very young boy in Venezuela. If he looks like a veteran on the field, that's because it's the truth."
Peter Alonso (ETA 2019)
Alonso, 23, crushed Double-A pitching to the tune of a .314/.440/.573 line with 15 homers in 67 games before being promoted to Triple-A, where he hit .260/.355/.585 with 21 homers in 65 games.
"Alonso combines elite exit velocities with strong plate discipline to produce huge righthanded power," Matt Eddy wrote for Baseball America on July 21, while ranking Alonso the Mets' second-best prospect (behind Gimenez). "The 2016 second-rounder has done nothing but mash since turning pro and has hit his way to Triple-A in short order. Alonso profiles as a middle-of-the-order masher and below-average defensive first baseman who will supply substantial value with his bat."
Jarred Kelenic (ETA 2021)
Kelenic, 19, hit .286/.371/.468 with six homers, six triples, 10 doubles, and 15 steals in 56 games split between the rookie level Gulf Coast League and Kingsport.
"He's universally considered one of the best pure hitters in the (Draft) class, with good feel for the strike zone and a mechanically-sound swing that he repeats well," John Sickels wrote for Minor League Ball shortly before Kelenic was drafted. "His hitting skills are quite polished, especially for a cold-weather bat."
Justin Dunn (ETA late 2019)
Dunn, 22, had a 4.22 ERA and 1.36 WHIP with 105 strikeouts in 89.2 innings (15 starts) after his promotion to Double-A Binghamton. Before being promoted, Dunn -- the Mets' first round pick in 2016 who is having a huge comeback season -- had a 2.36 ERA and 1.27 WHIP in nine starts for High-A St. Lucie.
"Dunn shows feel for three pitches and throws from an effortless delivery, making his 93-94 mph fastball and hard-breaking slider play up," Josh Norris wrote in his latest writeup at Baseball America. "Improved fastball command and manipulation as well as enhanced feel for his changeup have made him tougher on lefthanders and more effective overall."
