When Baseball America names its 2013 Minor League Player of the Year on Wednesday, Byron Buxton’s dream season is expected to reach another plateau.

According to a person familiar with the process, the Twins’ megaprospect is a “good bet” to receive the honor. A second source agreed with that assessment but would not confirm Buxton’s selection, citing the publication’s insistence on delaying the announcement until Wednesday.

This would mark just the second time in the award’s 33-year history that a Twins prospect would be honored. Franchise catcher Joe Mauer was selected in 2003, his third professional season.

Other strong candidates include Twins Double-A third baseman Miguel Sano, Triple-A outfielder George Springer (Houston Astros), Double-A right-hander Archie Bradley (Arizona Diamondbacks), Class A third baseman Joey Gallo (Texas Rangers), Double-A shortstop Javier Baez (Chicago Cubs) and Class A right-hander C.J. Edwards (Cubs).

Sano, Springer, Gallo and Baez each hit 35 or more home runs, while Bradley and Edwards each posted sub-2.00 earned-run averages. However, Buxton achieved his stunning level of production at age 19 during his first full season of professional baseball.

The multiskilled center fielder overwhelmed the Midwest League before earning a June 23 promotion to the Florida State League.

In 68 games with Class A Cedar Rapids, Buxton hit .341 with 33 extra-base hits, 32 stolen bases and a combined on-base/slugging percentage of .990, helping the Kernels win the first-half title.

The Baxley, Ga., product recently was named Midwest League Most Valuable Player in a vote of league managers, edging out Houston Astros shortstop prospect Carlos Correa, taken one spot ahead of Buxton atop the 2012 amateur draft. Correa spent the full season with Class A Quad Cities.

Buxton, the Twins’ highest draft choice since Mauer in 2001, received a $6 million signing bonus as the No. 2 overall pick.

In 57 regular-season games with high-A Fort Myers, Buxton hit .326 with 16 extra-base hits, 23 stolen bases and an .887 OPS. Though slowed in early August by an injured right big toe, Buxton rallied to hit .402 in August, his highest average for any month.

Florida State League managers voted him Topps Player of the Month for August.

Overall this season, in 488 at-bats, Buxton hit .334 with 19 doubles, 18 triples, 12 home runs, 77 runs batted in, 76 walks, and 55 stolen bases in 74 attempts (.743 success rate).

Buxton began the year ranked No. 10 on Baseball America’s Top 100 Prospects list, but by midseason he had ascended to the top spot. He joined Sano at the All-Star Futures Game in July and will head to the Arizona Fall League at the start of October for seven weeks of competition against the game’s most advanced prospects.

Sano, who led the Twins organization with 35 home runs, was a Minor League Player of the Year finalist. He hit a combined .280 with 30 doubles and five triples, but struggled to a .236 batting average at Double-A New Britain after being promoted June 9.

The 20-year-old third baseman from the Dominican Republic was rated Baseball America’s No. 3 overall prospect at midseason.

Buxton and Sano recently were profiled in Sports Illustrated. They even shared a small corner of the cover.

Recent winners of the Baseball America honor include Tampa Bay Rays outfielder Wil Myers (2012), Los Angeles Angels outfielder Mike Trout (2011), Atlanta Braves outfielder Jason Heyward (2009) and Baltimore Orioles catcher Matt Wieters (2008).

Ex-Twins outfielder Delmon Young won the award in 2005 while a Rays prospect.
