The Diamondbacks agreed to a deal with veteran catcher Chris Iannetta and subsequently designated Graterol for assignment. The 27-year-old catcher has only appeared in nine major league games over his 10-year professional career. He doesn't figure to serve as anything more than organization catching depth wherever he lands.
Prior to being acquired by the Angels in December of 2016, Maldonado acted as the Brewers' back-up catcher for the better part of the past five seasons. Known more for his defensive prowess, the veteran catcher owns a career batting average of .217. He'll likely receive a fair amount of playing time for the Angels in 2017, but doesn't figure to provide much of an offensive impact.
Terms and length of the contract were not immediately reported. He has proven to be a solid defensive catcher over the years, but has been of very little use in fantasy leagues, as he has hovered around the Mendoza Line in each of the past two seasons and offers little power and doesn't even get on base at a solid clip anymore. Look for him to share time with Chris Herrmann behind the dish this year.
The terms of the agreement were not announced. He appears poised to open the year as the Diamondbacks' starting catcher. Despite his impressive play in limited time last season (117 wRC+ in 166 plate appearances), Herrmann does not project to hit enough to be valuable in most one-catcher formats. His 2016 season ended prematurely because of a broken hand, but he is expected to be ready to go for spring training.
Terms of the agreement were not made public. Leon is coming off what may go down as a career year, slashing .310/.369/.476 over 283 plate appearances. However, every projection system forecasts massive regression, and he will have to compete with Christian Vazquez and Blake Swihart for regular duty behind the dish.
Vogt's 2016 season didn't quite meet the standards of his previous two, posting lower numbers in all three slash statistics, but he still managed to make the All-Star Game and cement himself as a leader on the A's. This was the first round of arbitration for the 32-year-old.
Despite playing hurt for much of the year, Grandal still managed to post a career-high .477 slugging percentage. He hit at an elite level when healthy, slashing .287/.410/.622 in the months of June and July, but the problem with him going forward is that he often isn't healthy. That aside, he remains a power bat with top pitch-framing skills behind the plate, so he'll get a pay raise of almost $3 million in his second round of arbitration.
He struggled in a major way with San Diego in 2016, batting .186/.255/.328 with a strikeout rate north of 30 percent. That said, Norris, who turns 28 next month, still packs a power punch and he figures to serve as the primary option behind the dish in Washington -- that keeps him plenty relevant in two-catcher leagues.
Romine hit .242/.269/.382 in his stint as the Yankees' back-up catcher in 2016, first working behind Brian McCann then Gary Sanchez. This was his first round of arbitration. With Sanchez clearly not going anywhere, he figures to see a similar back-up role in his next season as well.
He is on track to enter the year as the Mets' No. 1 catcher, but on the heels of posting a 74 wRC+ with just four home runs and a .247 average in 276 plate appearances, his draft day price will be as low as ever. While a bounce back of sorts should be expected, d'Arnaud no longer looks like a high-upside option at the position.
