Johnson's career will go down as a large what-if, an arm with a significant amount of both talent and ailments. The 32-year-old won an ERA title back in 2010 with the Marlins and had established himself as one of the league's best young pitchers, but an unrelenting series of injuries led to him throwing his final major league pitch in 2013. Now, after undergoing a third Tommy John surgery, Johnson is hanging up the cleats.
Andrus said that he's being careful while rehabbing his injury, but plans to be ready for the upcoming campaign. He also said that the groin ailment limited his ability to steal bases throughout 2016, so an increase in stolen base production may be in order for the 28-year-old shortstop.
The Reds have dangled Cozart's name in trade talks this offseason but haven't made any tangible progress. They still need to find a way to make room for both Jose Peraza and Dilson Herrera to play, but both Cozart and Brandon Phillips remain ahead of them respectively.
The terms of the agreement were not announced. Iglesias was once again a wizard on defense and well below-average hitter (73 wRC+) in 2016. His elite glove will keep him in the lineup most days, but there's not much value to extract from a fantasy perspective.
The 25-year-old middle infielder faces a job battle this spring, as he, Nick Ahmed, Brandon Drury and Ketel Marte will be competing for two starting spots. Owings is considered the favorite to start at shortstop in 2017, but his 86 wRC+ and subpar defense last season certainly opens the door for competition.
Terms of the agreement were not available. Bogaerts set a career high last season in home runs (21), steals (13), runs (115) and RBI (89). He should continue to be a five-category force at shortstop in 2017.
The Cuban shortstop took a step backward with the bat after two decent years in 2014 and 2015, hitting .236/.283/.311 in 2016. As usual, that light hitting was made up for by excellent defense at shortstop. This was Hechevarria's second round of arbitration, with him likely on track for free agency after the 2018 season.
Miller experienced a massive power spike in 2016, slugging a career-high .482 and 30 home runs. His reward will be a strong showing in his first round of arbitration.
His defense slipped in his age-25 season, but Gregorius made up for it to an extent with a significant power boost. Gregorius more than doubled his previous career high of nine home runs (established in 2015) while posting the best contact rate of his career. He'll make for a decent consolation prize for those who miss out on one of the young superstars at the shortstop position.
Mercer posted a .256/.328/.374 line well within career norms in 2016 and was rewarded with a raise of more than $2 million. He's on track to hit free agency before the 2019 season at the age of 32.
