MLB: Minor League 2016 All-Stars, Pitchers
As the World Series is underway to close out the MLB season, it’s good to look back at the play for the season. Who were the best in the minor leagues in 2016?
This is the in-depth effort of Benjamin Chase as he pours over thousands and thousands of innings of MiLB.tv coverage, reviewing as many minor leaguers that he can get his eyes on. Today’s post will feature the best pitching performances in 2016 in the minor leagues.
Ben scoured the minors, reviewing the stats, taking into consideration the league context and park context as well, not just raw numbers. Some preference will be given to guys who performed at advanced minor leagues if the numbers are close in general.
For hitters, a player needed to have 300 plate appearances total in the minor leagues to be considered for this list. Performance at the major league level was not taken into consideration at all. By no means is this intended as a comprehensive list of all excellent performers at each position, but just a list of the guys that I considered for the top spot.
Before we head into the list, a disclaimer – this is not a list of the best prospects, so if a guy who is a top 10 rated player on national lists didn’t have the stats that someone else did, he won’t be here. Numbers are the only thing that matter to getting on the list. The only time outside factors mattered was in selecting the final representative at each position, when factors like ballpark, league, age, and other factors were considered.
This list will have five starters and four relievers highlighted, but plenty of “honorable mentions” as well!
Starting Pitchers
Brock Stewart, RHP, Los Angeles Dodgers, A+/AA/AAA, 24 years old
Stats: 121 innings, 1.79 ERA, 0.88 WHIP, 19/129 BB/K ratio
Coming into the season, there wasn’t a whole lot of expectation for Stewart. He was originally a sixth round selection in 2014 as a “senior sign” selection from Illinois State University, so many felt that Stewart would be roster filler.
Stewart returned to high-A Rancho Cucamonga to start 2016, and after posting a 5.43 ERA in 2015 at the level, Stewart came out and dominated in two starts before being quickly promoted to AA, where he didn’t seem phased at all.
After posting a 0.82 ERA and 1.37 ERA in the Cal League and Texas League, both hitters’ leagues, a promotion to Oklahoma City in the Pacific Coast League looked like a possible issue, but Stewart just kept roasting, posting a 2.49 ERA in nine PCL starts.
He did shuffle a bit in the major leagues in seven appearances, five of them starts, but Stewart did have a tremendous minor league season, being recently selected as the pitcher of the year through MiLB.com.
Stewart will likely start at AAA to start 2017, and his control will be the key to his success. He walked just 4.1 percent of hitters in the minor leagues, but in the major leagues, part of his struggles was a 9.5 percent walk rate, over double that minor league rate. That forced Stewart into grooving some pitches to get strikes, and those pitches got pounded by big league hitters.
Next: Pirate Ace
Tyler Glasnow, RHP, Pittsburgh Pirates, AA/AAA, 22 years old
Stats: 116 2/3 innings, 1.93 ERA, 1.17 WHIP, 68/144 BB/K ratio
Glasnow is a guy that certainly intimidates the moment he steps off the team bus, standing 6’8″ and fairly well built, listed at 225 pounds and possibly even 15+ pounds more with all good weight.
His height allows him a unique downward plane on his hard fastball, and he has a wicked breaking ball to go with it. However, like many guys at his height, Glasnow can have issues with repeating his delivery, leading to some command issues.
The Pirates snagged Glasnow in the fifth round of the 2012 draft, and he’s been nothing but impressive ever since, with only injuries slowing him down. In fact, he’s not even had a partial season at any stop that he posted above a 3.75 ERA until he got to the majors this season.
His regular season ERA totals have been 1.88, 2.10, 2.18, 1.74, 2.39, and then 1.93 this season. Add in a strikeout rate of nearly 1/3 of all hitters he faces at 32.1 percent, and Glasnow definitely has the makings of a future ace.
He did have some struggles with his walk rate in the major leagues, though he did still have similar high strikeout rates, striking out 24 in 23 1/3 major league innings.
Glasnow is likely going to be at the back of the Pirate rotation in 2017 due to not exceeding 125 innings in any season in his career and needing to ease into a heavier workload, but he has all the makings of a future front line guy.

Honorable Mentions
These are a few guys who did not make the innings requirement that I had, but had tremendous seasons:
Yadier Alvarez, RHP, Los Angeles Dodgers, Rookie/A, 59 1/3 IP, 2.12 ERA, 1.03 WHIP, 21/81 BB/K
Alec Hansen, RHP, Chicago White Sox, Rookie/A, 54 2/3 IP, 1.32 ERA, 0.81 WHIP, 20/81 BB/K
Michael Kopech, RHP, Boston Red Sox, A-/A+, 56 1/3 IP, 2.08 ERA, 1.10 WHIP, 33/86 BB/K
Chris Paddack, RHP, Miami Marlins/San Diego Padres, A, 42 1/3 IP, 0.85 ERA, 0.59 WHIP, 5/71 BB/K
Sixto Sanchez, RHP, Philadelphia Phillies, Rookie, 54 IP, 0.50 ERA, 0.76 WHIP, 8/44 BB/K
Next: First Reliever
Relief Pitchers
Jonathan Holder, RHP, New York Yankees, A+/AA/AAA, 23 years old
Stats: 65 1/3 IP, 1.65 ERA, 0.66 WHIP, 7/101 BB/K ratio
Holder was drafted in the sixth round out of Mississippi State, and as a starter many thought that Holder would be more of an org filler with a heavy fastball that sits in the low 90s that he can spot exceptionally well and a looping curve being his primary pitches.
After good results in his first two seasons in the system, the Yankees moved Holder into the bullpen this season, and the results were flat-out dynamic. Holder was ridiculously difficult for hitters to adjust to coming from the bullpen in the minors.
He worked his way from high-A all the way to the major leagues this season. He struggled with his control with the Yankees, which was the primary issue for him in the big leagues, but his excellent control allowed his stuff to play up all season long.
He may not have major velocity, but he could be a guy that works in the middle of a bullpen well and even fits at the back end of a bullpen in the right situation. There are some excellent relievers who have lived on lesser velocity and pinpoint control, like Mark Melancon, so there is a path to success for Holder for sure.
Next: Padres Dominator
Kyle McGrath, LHP, San Diego Padres, A+/AA/AAA, 23 years old
Stats: 67 2/3 IP, 0.93 ERA, 0.75 WHIP, 10/78 BB/K ratio
The ultimate in late-round draft production, McGrath was a 36th round selection in 2014 out of a very good baseball program at the University of Louisville. He was used as a reliever in college, and the Padres kept him in that role.
McGrath spent all but one game with low-A in 2015, but he pitched well, and his control was the biggest notable thing about his performance. He struggled in college with his control, but keeping the ball in the zone allowed his stuff to definitely play up.
In 2016, he took things to a different level. He pitched in the Cal League, Texas League, and made one appearance in the Pacific Coast League, all hitters’ leagues, yet he put up numbers that were ridiculous all season.
McGrath does not have an elite fastball, rarely touching 90 MPH, but he adds in a hard-breaking slider and a change with excellent movement. Both the change and slider work well arm side low in the zone.
Due to his excellent slider, solid control, and the example of Andrew Miller this postseason, McGrath is getting stretched out some in the Arizona Fall League this winter with a stated intent to use him for multiple innings out of the bullpen (not moving him to the rotation). That could make him even more of a weapon for the Padres going forward.
Most likely McGrath will be in AAA to start 2017, but with his ability to work multiple innings from the left side, he could certainly earn a spot in the bullpen out of spring training in the major leagues or move quickly up to San Diego.
Next: Tiger Closer
Joe Jimenez, Detroit Tigers, A+/AA/AAA, 21 years old
Stats: 53 2/3 IP, 1.51 ERA, 0.80 WHIP, 17/78 BB/K ratio
Jimenez was signed as a power arm out of the Puerto Rico Baseball Academy by the Tigers, and he’s been tremendous in the bullpen ever since. He’s moved his way into their future closer role, and he’s currently considered as highly thought-of as a closer prospect since perhaps when Craig Kimbrel was coming through the Atlanta Braves system.
Jimenez has an elite fastball that can not just touch triple digits, but also has excellent movement low in the zone. He adds in an excellent slider to go along with the fastball, and while he’s struggled at time to control the slider, he has still had success ever since signing with the Tigers.
Many were surprised that the Tigers left Jimenez in the minor leagues for September rather than calling him up as he moved from high-A through AAA with success at each level.
As long as Jimenez keeps the ball low in the zone, he does an excellent job of keeping the ball in the park and getting plenty of weak contact by those who do make contact off of him. Overall, though, his strikeout rate has been 13 K/9 throughout his minor league career.
It’s very probable that Jimenez starts in the Detroit bullpen in 2017, and his role will have a lot to do with whether the team brings back Francisco Rodriguez on a $6M option for 2017, which would be quite affordable. K-Rod could be a solid mentor for Jimenez to ease him into the majors, much like Troy Percival did for K-Rod when he came up.
Next: Astro Journeyman
James Hoyt, RHP, Houston Astros, AAA, 29 years old
Stats: 55 IP, 1.64 ERA, 0.87 WHIP, 19/93 BB/K ratio
One of the more fun things about baseball is the variety of ways that players come into the league. Hoyt is the best example of that. He was pitching in independent ball (and even the Mexican League) when the Atlanta Braves signed him before the 2013 season.
He came in as a 26-year-old reliever into the Braves system, and he showed some excellent skills in 2013 and 2014 before being part of the trade that also brought catcher Evan Gattis to Houston.
Hoyt leans heavily on his hard slider, which has tremendous plane coming from his 6’6″ frame, generating a ton of swing and miss. His fastball is only in the low-90s, though he does get excellent movement low in the zone from the pitch. He also mixes in a cutter and a change as well.
One of the interesting things with Hoyt has been his use of multiple arm angles to help with his effectiveness. This has not affected his control, but he can fall in love with one arm angle if he has success for a time.
Hoyt did make his major league debut with Houston this season, and he had some success with the big league club. He should be a contender for a spot in the Astros bullpen in 2017.
