CLEVELAND -- Development is the primary goal for the prospects who take the field in the Arizona Fall League each year. Winning is just a bonus.
A handful of the Indians' top prospects were fortunate enough to experience the latter with Surprise, which won the AFL championship with a victory over Mesa on Saturday. More important to Cleveland was the fact that this select class of players -- headed by outfield prospect Tyler Naquin, the club's fifth-ranked prospect, according to MLB.com -- concentrated on development in specific areas.
"We want our guys to be focused on really pushing the envelope to find out how good they can be," said Ross Atkins, the Indians' vice president of player development. "The Arizona Fall League is very much a development league. It just has the elite talent in it. And it isn't just the industry's elite talent, this is our elite talent."
The goals are tailored to the individual. The tasks can range from working on a specific pitch, trying to pick up on pitcher tendencies, pushing things defensively to learn limits or a variety of other concepts.
For Naquin -- Cleveland's first-round pick (15th overall) in the 2012 First-Year Player Draft -- there were three main goals. The Indians wanted the outfielder to continue his work on a change to his hitting mechanics, focus on stealing bases and gain even more experience in center field.
From the moment the Indians drafted Naquin, the outfielder has been on board with trying to identify ways to improve his game.
"He's extremely tough and extremely open-minded," Atkins said. "I would say, relative to thinking about improving, thinking about the big picture, having a vision for himself, he's elite in that realm."
In 27 games for Surprise this fall, the 22-year-old Naquin hit .339 (39-for-115) with a .400 on-base percentage and a .417 slugging percentage. The lefty-swinging outfielder mixed in one home run, four doubles, one triple, four stolen bases, 11 walks, 18 RBIs and 22 runs in AFL play.
It was a continuation of a solid 2013 season for Naquin, who posted a .269/.334/.405 slash line in 126 games between stints with Class A Advanced Carolina and Double-A Akron. Along the way, he produced 10 homers, 30 doubles, six triples, 15 stolen bases, 46 walks, 48 RBIs and 78 runs in his first full Minor League season. Naquin also had 11 assists from the outfield this year.
About midway through the season, Naquin took on some changes to his swing, which he continued to implement during his stay in the AFL.
"It took a vision and it took a lot of courage and it took conviction," Atkins said. "He had all those things, and it wasn't something that we went to him and said, 'You have to do this.' On the contrary, it was him being a student."
Naquin, who was more upright in his stance when the 2013 season began, lowered his hands and focused on using his lower half more in both his setup and swing. The outfielder's overall numbers dipped in the season's second half, but such changes take time and Cleveland has been encouraged by the results, especially in the AFL. Naquin has shown improvement with consistent hard contact and strike-zone discipline.
"The adjustment he's made allows him to see the ball longer," Atkins said. "It really was a significant adjustment for him, and he's obviously having success with it."
Here is a glance at the other Indians prospects who took part in the Arizona Fall League:
