"Our perception of the value in this instance was greater than the value at the end of July," Alderson explained on Tuesday. "We very definitely feel this was a better package for us than we could have obtained in July."
Hererra is on pace to make his big-league debut in 2016, MiLB.com's Jonathan Mayo told MLB Network late Tuesday afternoon.
According to Mayo, Herrera will probably slot in around number 10 on the team's top 10 prospect list next season.
"They're getting a pretty good middle infield prospect," Mayo said. "He's shown an ability to hit for average. He's got a little pop. He runs pretty well. He should be able to stay at second base and provide some pretty good offense both with his legs and bat."
Mayo believes Herrera needs to work on pitch recognition and plate disciple, which could help expedite his path to the big leagues.
I talked with one rival player development person, who has watched Herrera, and he was pretty excited for the Mets to be getting this kid. He told me Herrera has flaws. He needs to hit the ball the other way more, he doesn't have a great arm (which is why he moved to second from shortstop), he must hit better against righties, and he needs to let the game slow down a bit. However, I was told Herrera has a lot of upside and is the type of infield prospect the Mets are sorely lacking. He's small, but packs the potential for a 20 HR, 20 stolen bases for a second base.
In the end, Alderson is left with Travis d'Arnaud, Noah Syndergaard and Herrera (by way of Buck), Wuilmer Becerra and a PTBNL in return for R.A. Dickey (with Josh Thole and Mike Nickeas), which is not a bad haul for a 38-year-old knuckleballer who is 10-12 with a 4.39 ERA this season. Hopefully these players -- Bucerra is just 18 -- turn in to productive big leaguers sooner than later...
