Most surprising and disappointing players of the 2016 MLB season

Ramos has struggled to stay healthy for much of his career and hit rock bottom in 2015 when he batted only .229-15-68 in 128 games. Following offseason LASIK surgery, Ramos is having a clear breakout in 2016, hitting .304-21-78 in 123 games.

D'Arnaud has been injury-prone, to say the least, during his MLB career. He had more injury issues this season and was relegated to backup catcher down the stretch for the Mets. With consecutive seasons of less than 300 at-bats due to injuries, d'Arnaud has a big season ahead to prove he can stay healthy in 2017.

It looked like Napoli's best days were behind him after his numbers declined the past two years. He revitalized his career in Cleveland this season, hitting more than 30 home runs for the first time after only hitting 18 in 2015.

Injuries have hindered Zimmerman since 2014 as he continues his steep decline. He hasn't been good for more than the occasional long ball this season, hitting only .214-14-42 through 387 at-bats. Despite three years and $46 million left on his contract, the Nats might have to look for an alternative this offseason.

There was no denying that Murphy was a solid player coming into this season, but few saw a potential MVP. He's been an incredible bargain for Washington after signing a three-year, $37.5 million contract during the offseason, hitting .348-25-102 through 520 at-bats.

It's not only Gordon's 80-game suspension for PEDs that has made him a disappointment. He actually has the lowest OPS among second basemen with at least 200 plate appearances at just .608, with a batting average that's down to .257 and only 11 extra-base hits through 269 at-bats.

Turner has been arguably the most valuable player in the Los Angeles lineup this season, hitting .271-27-81 through 498 at-bats. That's not bad for a player who started late after offseason knee surgery and had never hit more than 16 home runs in a season before 2016.

Coming off an awful first season in Boston, Sandoval showed up to spring training overweight and saw only six at-bats before his season ended with a shoulder injury. He has three pricey seasons left on his contract, and the Red Sox could decide to just cut their losses if he doesn't show up ready in the spring.

The Cardinals came into spring training with Jhonny Peralta and Jedd Gyorko as their shortstop options, and Diaz really wasn't on the radar after they exposed him to waivers last year. However, Diaz has been quite the surprise for the team, hitting .313-15-59 through 358 at-bats as their primary shortstop, when healthy.

Hitting .300 and showing solid defense last season, the Tigers thought they were set with Iglesias at shortstop. He's regressed severely at the plate this season, hitting only .246 through 418 at-bats with a .624 OPS.

Duvall reached minor league veteran status before this season but finally got a regular opportunity in the majors with the Reds. He's made the most of his shot, hitting 30 home runs and making the NL All-Star team.

Colorado traded Corey Dickerson after signing Parra to a three-year, $27.5 million contract during the offseason. He's been a bust, especially considering his Coors Field home, hitting just .255-6-36 in 337 at-bats and suffering injuries throughout the season. The Rockies could cut bait soon with several young outfielders on the cusp of the majors.

Bradley has turned himself from a bust to an elite center fielder this season, hitting .272-24-84 in 507 at-bats while playing elite defense. He looked lost at the plate through his first three seasons, but Bradley's athleticism has finally won out.

Gomez was terrible after being traded to Houston last season, but the team hoped he would rebound after resting in the offseason. Somehow he's been even worse in his walk year, eventually getting released by the Astros. He's played better since joining the Rangers but is still hitting only .211-9-41 in 360 at-bats overall this season.

We knew Trumbo had power, but it was unclear if he'd ever hit 30 home runs again after two down years. Apparently, moving to Camden Yards was all he needed to get on track. He's led the AL in home runs for much of the season, surpassing 40 home runs for the first time as he heads toward free agency.

Many hoped Puig would get on the right track with a new manager, but he now seems more lost than ever. He reportedly raised hell after getting demoted to Triple-A and has the lowest OPS of his career. The elite player we saw over his first two seasons is now a distant memory.

The sabermetric indicators showed that Hendricks could be an excellent pitcher before this season, but no one expected him to lead baseball in ERA. He has an excellent shot to win the NL Cy Young with a 2.03 ERA in 173 innings for the surging Cubs.

Shields' velocity continues to decline, and so do the results. After posting a disappointing 3.91 ERA last season, Shields had a 4.28 ERA in 11 starts with San Diego before getting traded to the White Sox. Since joining the AL, he's been the worst pitcher in baseball with a 7.30 ERA in 18 starts. He's allowed a whopping 28 home runs in 90 innings for Chicago.

Few knew who Guerra was prior to this season, but the former Independent League pitcher has turned into an ace for the Brewers. He has a sub-3.00 ERA in 20 starts for the team.

Gray's year has been forgettable, with a 5.74 ERA in 21 starts and arm issues that have likely ended his season. He's struggled with his control and saw his home run rate from last season double after finishing third in the AL Cy Young voting in 2015.

A pitcher with incredible stuff but no command before 2016, Sanchez has transformed into Toronto's ace. He's finally established his control and has a 3.17 ERA through 27 starts for the Blue Jays. The team has tried to lighten his workload late in the year with an eye toward his future.

Arizona acquired Miller from Atlanta in a trade that looked lopsided already, despite Miller's 3.02 ERA and All-Star appearance in 2015. Now it looks like one of the worst trades ever after Miller has posted an ERA above 7.00 through 17 starts this season.

Bedrosian's father, Steve, won the Cy Young in 1987 for the Phillies. Based on the younger Bedrosian's performance this season, he could also earn accolades during his career. The Angels reliever has been the team's best pitcher in the pen, with a 1.12 ERA in 45 appearances. His season ended early due to elbow surgery, but he will be ready in spring training and could have a shot at the closer role.

Rosenthal converted 14 saves but mostly looked lost this season, apparently pitching through arm issues. He had a 5.13 ERA and horrendous 7.3 walks per nine innings in 40 appearances before going on the DL.

Trevor Rosenthal's replacement at closer, Oh has been amazing in his first season in the majors. The Cardinals signed him to a relatively cheap two-year deal worth up to $11 million. He's produced a sub-2.00 ERA and is set to reach 100 strikeouts as an elite reliever.

Washington's closer just last season, Storen hasn't pitched well as a middle reliever this season. He has an ERA near 6.00 between Toronto and Seattle, getting traded to the Mariners in late July.
