The 24-year-old with the slight frame slashed .318/.363/.534/.897 last season -- all career highs -- and cleared the 30-homer mark for the first time in his career. He finished four steals shy of being a 30-30 player, a mark he's likely to threaten in 2017. Betts collected many accolades as a result -- second in the MVP voting, a first-time All-Star, a Gold Glove and a Silver Slugger. The forecasts for Betts had him hitting for power, but 31 homers was not in the tarot cards. Unlike his previous season, there were no down periods; Betts hit .266 in April and warmed up as the weather did, hitting .368 in July and .378 in August. It was during those warm-weather months that manager John Farrell dropped him from leadoff to third and fourth in the order, where his bat drove in 39 runs in 48 games. The Red Sox will miss David Ortiz, but Betts has emerged as an unlikely middle-of-the-order presence.

Former Boston general manager Ben Cherington made some roster additions that cost him his job, but his best personnel move is the one he never made. Amid pressure to trade Betts for Phillies starting pitcher Cole Hamels, Cherington held his ground and it paid off for Boston. Betts has become one of the more dynamic players in MLB. In mid-June, Betts was hitting .234 with a .659 OPS. From that point on, he hit .329 with a .925 OPS. Betts evolved as a dangerous leadoff hitter who added a power element to his game, finishing third on the team with 18 homers and third with 77 RBI. The 22-year-old’s added power was the result of a change in approach that had him swinging at more pitches, though that cost him some on-base ability (.341 OBP). Betts has an elite power/speed combo with good defense at a premium position. He will continue to hit leadoff and may move to right field if Jackie Bradley remains with the team.

Betts appeared at three levels in 2014, eventually finishing the season as a regular outfielder in Boston. He had two stints in Boston and it looked like he wasn't ready for the show in each. It appeared the Red Sox may have rushed him, particularly defensively as Betts had little on-the-job training after moving from second base to outfield. There's still some work to do in the field, but the offense he showed at every level of the minor leagues eventually played at the major league level. Betts hit .317/.388/.462 (.849 OPS) in 116 plate appearances in September. Betts is probably the best option on the team to hit leadoff, a spot of trouble for the Red Sox last season until Brock Holt stabilized it. Look for Betts to get a ton of work in the outfield in spring training to the point where Boston feels comfortable taking him north to play on the grass at Fenway Park.

Betts, a fifth-round draft pick in 2011, was the organization's breakout prospect in 2013. He began the year at Low-A Greenville, initially struggled but maintained a good plate approach and kept his on-base percentage up. He eventually found his groove and had a 19-game hitting streak as well as a 33-game on-base streak. Betts hit 15 homers, had 81 walks and stole 38 bases in stops at Greenville and High-A Salem. With a good swing and the ability to work counts it's easy to see why the Red Sox like him. With Dustin Pedroia presumably the second baseman in Boston for years to come, Betts may eventually switch positions -- he played shortstop in high school. But that decision won't be made until later. The Red Sox like to challenge their prospects, so we might see Betts begin the season against older competition at Double-A Portland.

Betts, a fifth-round draft pick out of high school in 2011, went professional after committing to play for the University of Tennessee. He's an athletic infielder with an ability to impact games with his legs. He stole 20 bags in 71 games for Short-Season Lowell in 2012. Betts has a nice swing that should produce line drives as he learns to manage the strike zone and improve his pitch recognition. He projects very little power potential, but could develop as a gap-to-gap hitter. Presently, Betts gets his bat on the ball, but it's not always solid contact. He'll be pressed to improve his good-contact rate in his first year of full-season ball at Low-A Greenville.
