Mark Prior, Jason Marquis, Jayson Nix, Brian Jordan. These names make up an esteemed class of MLB draftees who have made a profound impact on the game after they were selected with the last pick of the first round of their respective drafts. After being drafted in that same slot last season, outfielder Brian Miller took a huge leap towards joining that group.
Reading up on Brian Miller's background you might learn that after going undrafted he made the North Carolina Tarheels as a true walk on. However, as Miller tells us, it wasn't exactly like that.
Despite not having to go through a formal try out though, Miller still had to prove himself worthy of cracking one of the nation's best baseball programs. That would happen a little later that summer when he was amongst nearly 50 players trying to crack a 25-man roster.
Miller made the team as the Tarheels' starting center fielder and proceeded to hit .288/.375/.326 as a freshman. He stole 10 bags in 12 attempts and was second on the team in K/BB% with a lowly 0.84 marker (16/19). A native of Raleigh, North Carolina, Miller often spent time on the other side of the fence at Boshamer Stadium, dreaming of pulling on the Carolina blue and white. Now, that dream was a pleasant reality, even if not in the way Miller envisioned it.
After his solid rookie campaign, Miller took his talents to the Coastal Plain League where he placed second in BA (.389) and led the league in OBP (.476) via its most hits (77) and also racked up a league-most 38 steals. He parlayed that to his sophomore year at UNC, where he absolutely exploded, hitting .345/.440/.469. His batting average ranked amongst the top 15 in the ACC, his 21 steals (in 26 chances) ranked fourth in the conference and his 56 runs scored ranked 10th. The 19-year-old continued to exhibit excellent plate vision, posting a 0.85 K/BB, a nearly identical mark to that of his rookie year and in almost 100 more ABs. During that breakout year, Miller started to become acclimated with the close-knit fabric that binds that UNC Baseball program together. According to Miller, it was a major catalyst in his success.
After a .327/.369/.387 showcase in the 2016 Cape Cod League, Miller's comfortability and compatibility with the UNC program continued to show true in his junior season last year when he hit .343/.422/.502. The biggest addition to his game here was a surplus of power as he slammed seven homers after managing just two in his first two seasons at the collegiate level. Once again, the emphatically patient Miller walked more than he struck out (38/35 BB/K), and he continued to be a menace on the basepaths where he added another 24 steals in 30 chances. He appeared on multiple ACC leaderboards including BA (11th), total bases (136, 9th), steals (2nd), hits (93, 2nd) and runs (61, 5th). All of it came in 271 ABs, most in the league. Miller was a key contributor to the Tarheels' 23-7 record, their division title and their #11 ranking in the nation. Indeed, Miller and the rest of his UNC teammates did big things that year, but if you ask any of them, including Brian, they will tell you they weren't the least bit surprised in themselves. According to Miller, the team is accustomed to success and counts on it day in and day out. According to Miller, this attitude had a profound impact on his career.
Enter Draft day 2017. Miller, by way of his five-tool type junior year, entered projected to go off the board in the second round only to hear the Marlins, with their competitive balance pick, call his name in the first round, 36th overall. Yes, the same Brian Miller that went unrecruited out of high school had become a first round draft pick. However, while he admits it was exciting hearing his name get called so early in the draft, Miller says his draft stock wasn't really a concern while he was playing for UNC. Instead, Miller had his sights set on making his friends and family proud.
Upon being selected, the Marlins forwent sending Miller to short season Batavia and instead sent him to full season A in Greensboro. This was music to Miller's ears as it was a short 80 mile trek from his home in Greensboro and an even shorter 50 mile hike from Chapel Hill, meaning he would continue to be surrounded by his friends and family and could keep reaping the benefits of his college coaches' expertise.
Feeding off the in-person support of his family and friends, Miller, despite being over a year younger than the average South Atlantic League player, started his big league career by slashing .322/.385/.416. He tore up the basepaths, stealing 21 bags in 27 attempts and scored 42 runs, quickly solidifying himself as the Grasshoppers' leadoff hitter. Though he admits there was a noticeable leap in the opposition's skill level that he had to adjust accordingly, Miller credits the successful start to his big league career to the time he spent facing some of baseball's top rising stars in the ACC such as fellow 2017 first rounder Brendan McKay (Tampa Bay) and 2016 second rounder Connor Jones (St Louis) and picking the brains of his star rotational teammates, Astros' 2017 first rounder Jacob Bukauskas who owned a 3.06 K/BB at UNC and Cardinals' 2016 third rounder Zac Gallen who posted a 3.67 K/BB in Tarheel blue.
A contact-or-bust singles swinger, Miller uses his plus-plus jets to collect extra bases. He exhibits fantastic plate vision and patience via a knowledge of the strike zone well beyond his years, allowing him to work at least deep and usually favorable counts. Miller's swing is one of the quickest in Miami's system. Using his excellent vision, he is able to wait out the break of a pitch and follow it all the way to the back of the glove. When he engages, Miller's swing flashes through the zone straight and narrow. His split stance allows him to step both in and out to his contact point and allows him to barrel up virtually any pitch on either side of the zone. All of that sounds and is great. But if you ask Miller himself, his mechanics are so soundly second-nature that he isn't concerned with them. Instead, he approaches his at-bats with a very simple, refined attitude.
Where Miller wants to do the most of his offensive damage and where he believes he can disrupt the game most advantageously is on the bathpaths.
Miller uses that same speed to cover ridiculous ground in the outfield, making him one of the best range defenders in the system, rivaling the likes of teammate Aaron Knapp and former/future teammate Corey Bird. If the Marlins' current system is rich with one thing it's speedy, top of the order outfielders. However, due to left-handedness, his pre-pro pedigree and his untenable patience and the fantastic beginning to his career, Miller may have the highest leg up on all of them. While the recently turned 22-year-old only competed in 57 games worth of affiliated action last year and while he will have to prove that he can endure a full season's worth of games, due to his coming virtually out of nowhere, turning into a first round draft pick, skipping short season ball and becoming one of the Greensboro Grasshoppers' most valuable players, Brian Miller earns our Minor League Player of the Year Award. We expect this will be the first of many times you hear his name this coming year. He should start the season in Greensboro (after a possible spring training invite) but with continued success, could move up to A+ Jupiter by the midseason mark.
