Players who helped themselves the most during 2017 spring training

With the Cardinals moving Matt Carpenter to first base, Adams was without a position going into spring training. However, he didn't sulk this offseason, losing a significant amount of weight and now hitting .294-4-7 this spring.

With Alex Dickerson fighting back issues, the San Diego outfield is wide open. Blash is taking full advantage, hitting .257-5-13 in 18 games. He's likely at least won himself a roster spot.

Boyd has all but locked up Detroit's fifth starter spot. The former top prospect has a 3.24 ERA in 16.2 innings and is still yet to allow a free pass.

If there was any doubt Broxton was Milwaukee's center fielder coming into the year, he's erased those doubts this spring. He's having a monster spring, hitting .395-3-10 in 14 games.

After struggling last season and being moved to the bullpen, Corbin has likely locked up Arizona's fifth starter spot with a good spring. He has a 3.44 ERA in five starts, including 17 strikeouts in 18.1 innings.

Demoted to the minors early last season, DeShields never produced like he did in 2015. He seems back this spring, hitting .289 with seven stolen bases. DeShields could be back as a useful backup outfielder.

Frazier entered spring training as Pittsburgh's likely utilityman after his strong showing late last season. What he's done this spring could give him even more playing time. Frazier is hitting .450 with four walks and only one strikeout, leading all batters in batting average this spring.

As poorly as Gibson pitched last season (5.07 ERA), the questions started to linger coming into the spring. He's quieted any doubt of a rotation spot with a 2.08 ERA in five starts.

Glover might have jumped Shawn Kelley for the Nats' closer job with a dominant spring. He's allowed only one run in eight innings with 11 strikeouts.

Fighting for a spot as a regular, Haniger has all but sealed it with his strong spring. He's hit .404-2-8 through 15 games played.

A veteran starter who didn't even appear in the majors last season, Kendrick could have a rotation spot to start the year in Boston between David Price's elbow issues and Drew Pomeranz's mechanical issues. He has a 1.96 ERA in 23 innings.

A top pitching prospect acquired from the Nationals for Adam Eaton, Lopez has been solid this spring. He has a 3.72 ERA in 19.1 innings with only five walks, likely securing a spot in Chicago's rotation.

Mancini's chance at a roster spot took a hit after the Orioles signed Pedro Alvarez this spring, but he's still doing his best to make the decision difficult. He's hitting .304-2-8 through 21 games.

Charlie Tilson was expected to be Chicago's center fielder, but an injury has opened up the door for other players. May had just a .662 OPS at Triple-A Charlotte last season, but his .349 batting average this spring has put him in the lead for Chicago's center field job.

Mejia could have a role as a swingman for the Twins with his spring. He has a 1.88 ERA in 14.1 innings, along with 14 strikeouts.

Mitchell has taken full advantage of his opportunity with openings in the Yankees' rotation. He has a 3.77 ERA and 12 strikeouts in 14.1 innings.

Brett Lawrie was released by the White Sox, and top prospect Yoan Moncada very well might be forcing himself onto the team. He's hitting .317-3-13 in 17 games this spring.

A former top prospect as a starter, Montero is pitching in relief after years of shoulder issues. The transition is working thus far, as Montero has a 2.70 ERA in 13.1 innings with 20 strikeouts. He's getting close to securing a bullpen spot.

The fifth starter spot was Morton's to lose after signing with Houston in the offseason. He's secured the spot with a 1.38 ERA in four starts, also showing the increased velocity that he did early last season in Philadelphia before suffering a torn hamstring.

The signing of Brandon Moss eliminated O'Brien's opportunity for the DH role, but he's done more than enough to make the Royals. The former catcher still features epic power and is hitting .333-6-13 this spring.

Park looked like a major bust after signing with the Twins last season, but he's clearly outplaying DH competitor Kennys Vargas this spring. The power hitter is slugging .818 with a 1.280 OPS.

2016 wasn't a great year for Reed, who struggled in his MLB debut, but he's started to get in tune this spring. He's hitting .306-4-11 with nine walks in 21 games. Unfortunately, Houston doesn't have a spot for Reed now with Yuli Gurriel expected to play first base.

Romano had a breakout year at Double-A Pensacola last season with a 3.52 ERA in 27 starts. With injuries to Homer Bailey and Anthony DeSclafani, Romano could be forcing Cincinnati's hand this spring with his incredible spring. He has a 1.17 ERA in 15.1 innings with 19 strikeouts.

After struggling late last season, there were real questions about Wacha's role heading into the season. He's won a rotation spot after posting a 2.65 ERA in five starts over 17 innings.

Coming off ankle surgery, no one has looked better than Walker this spring. He has a 3.57 ERA in five starts with a 25/2 strikeout-to-walk ratio in 17.2 innings. While he already had a rotation spot locked, Walker has likely moved himself up in Arizona's rotation.
