Finally we have some real data to work with in the early part of the minor league season. While everyone is focused on what’s going on at the major league level, there is a lot happening at the secondary levels that should be highlighted. Today we will look at Double-A hitters and pitchers that are getting off to hot starts and whether they have a chance to reach the majors anytime this year.

Eastern League

Jorge Alfaro, Reading Phillies (Philadelphia)

As one of the main pieces coming back to the Phillies in the deal that sent Cole Hamels to Texas, Alfaro has some expectations to live up to. He was a Baseball America Top 100 prospect in 2014 and 2015, but fell off the list headed into the 2016 season. He’s shown power in the past—Alfaro hit 17 home runs between High-A and Double-A in 2014—but that number fell to five in 213 plate appearances. He is, without question, the Phillies’ catcher of the future and the team would love to see him regain that power stroke. He is 9-for-18 with five RBIs over his first four games for Reading, though he has not hit a home run. If Alfaro can continue his hot hitting, he will jump to Triple-A and has an outside shot to receive a late season call to Philadelphia.

David Dahl, Hartford Yard Goats (Colorado)

Over his first seven games, Dahl has clubbed four home runs while driving in seven at Double-A Hartford. He is one of the top prospects in the Rockies’ organization and in due time, his power is going to play quite well at Coors Field. Outside of the impressive power, Dahl is off to a relatively quiet start in the batting average and on-base departments. He is just 6-for-25 (.240) to start the season with 12 strikeouts. Dahl has decent speed and developing power and could be a 20/20 player at the major league level if everything pans out. He should be in Triple-A by June and will likely get a late season call-up, especially if the Rockies move players prior to the trade deadline.

Aaron Wilkerson, Portland Sea Dogs (Boston)

It’s been a hot start to the 2016 season for the 27-year-old Wilkerson. He has meddled in the Red Sox organization over the last two years after playing in the Independent League in his early-to-mid 20s. Wilkerson has shown the ability to strike hitters out (9.5 K/9) throughout his minor league career while also keep his walks (2.4 BB/9) in check. Let’s me be clear—Wilkerson is not a prospect, but that doesn’t always mean a player can’t find success. If the Red Sox were to need a spot starter down the line, they will likely give Wilkerson a long look.

Southern League

Chesny Young, Tennessee Smokies (Chicago Cubs)

It’s early in the season, but Young is back to his hitting ways batting .350 with two homers over his first 20 at-bats. Since being drafted in the 14th round of the 2014 Amateur Draft, Young has hit over .315 at every minor league level he’s reached where he appeared in more that two games. Over 779 minor league plate appearances, Chesny has walked 75 times while striking out just 84 times. Not only does he make great contact, but also he’s also versatile in the field. Chesny played every position except pitcher at High-A Myrtle Beach last season and type of flexibility could be his ticket to the majors in the future.

Guillermo Heredia, Jackson Generals (Seattle)

The Mariners picked up a Cuban player during the offseason, though it wasn’t high profile because Heredia was exempt from the international bonus pools. He hasn’t played since 2014, so it is encouraging to see him hit .455 over his first 22 at-bats at Double-A Jackson. He’s known for his defense and decent speed, but Seattle is hoping he can bring something to the table with his bat. Given his years in the Cuban National Series, he could ascend through the Mariners’ minor league system quickly and could be a September call-up.

Edwin Diaz, Jackson Generals (Seattle)

Diaz was drafted in 2012 by the Mariners and has worked exclusively as a starter. He has a 16-to-1 K/BB ratio over two starts at Double-A this season and has given up just two runs over 11 innings pitched. He doesn’t have the top prospect tag attached to him, but given his strikeout ability; he could wind up being a number three or four starter in the majors. Much like the aforementioned Wilkerson, Diaz is a candidate to make a spot start at some point this year if the need arises. Even if he doesn’t reach the majors this season, Diaz will likely be ready to help the big league club in 2017.

Texas League

Alex Bregman, Corpus Christi Hooks, Houston

The second overall pick in last year’s Amateur Draft began the season at Double-A and has gotten off to a raucous start. Over his first six games, Bregman is batting .333 with three home runs and five RBIs. In 66 games at Low-A and High-A last season, Bregman hit a combined four home runs, so the immediate increase in power is something watch going forward. Bregman is already 22 years old quite polished, but he’s still likely to spend the majority of the year in the minors.

Raul Mondesi, Northwest Arkansas Naturals (Kansas City)

It appears that Mondesi is finally filling out his frame as he has hit two home runs over his first six games at Double-A. Mondesi has been known for his speed coming up through the minors and he’s not disappointing in that category either with four steals on the year. The 20-year-old spent most the 2015 season in Double-A, so his stay this season will likely be short. Much like several other players mentioned, he could receive a late season call-up.

Alec Mills, Northwest Arkansas Natural (Kansas City)

During the early part of his career, Mills split between being a starter and a reliever. He’s made the full transition into being a starter and fared quite well at High-A Wilmington last season as he posted a 3.02 ERA and an 8.8 K/9 over 21 starts. He’s picked up right where he left off in this season in Double-A with a 0.82 ERA and 16 strikeouts in his first 11 innings. Mills is a member of the Royals’ 40-man roster, though it’s likely that he won’t see the majors this season.
