Gray, a first-round Draft pick in 2011, will earn $3.575 million, according to MLB Network's Jon Heyman -- a significant uptick from the $527,500 he earned in '16, during which he went 5-11 with career-worsts in ERA (5.69) and WHIP (1.496) over 117 innings.

Entering the 2016 season with monumental expectations, Gray was scratched from his Opening Day start due to food poisoning, and he later weathered two stints on the disabled list. The first was with an upper back strain and the latter with a strained right forearm in August, returning nearly eight weeks later to toss an inning of relief in a Sept. 28 game against the Angels.
Despite the setback, Gray -- an American League Cy Young Award finalist in '15 -- is still considered among the game's top pitchers. As such, and given his three years of club control remaining, Gray has been a speculated trade target the last two seasons, a stretch in which the A's have gone 137-187.
Vogt, 32, will enter his fifth season with Oakland and third as the everyday catcher. The veteran has slashed .256/.322/.424 with 32 homers and a team-best 127 RBIs and .746 OPS over the past two seasons.
Hendriks, 27, compiled a 3.76 ERA and 1.284 WHIP with 71 strikeouts and 14 walks over 64 2/3 innings in his first season with the A's. The Australian was acquired last November from the Blue Jays as part of the Jesse Chavez trade.
Davis, 29, is projected to earn $5 million in '17, per MLBTradeRumors.com.
