Gray followed up his successful first full MLB season in 2014 with a 2.73 ERA and 14 wins over 31 starts in 2015. Gray was one of the Cy Young favorites into September, but a few late season blow-ups pushed his ERA up more than a half point in the last month of the season. Gray did not rediscover his strikeouts from his initial big league debut (9.4 K/9 in 2013), but he did manage to cut his walks down from 3.0 BB/9 in 2014 to 2.6 in 2015. Gray supplements his average strikeout rate by limiting line drives with his 16.6-percent line drive rate — good for fourth best among all qualified starters in 2015. Gray now has two and a half fantastic seasons under his belt and while he will not get you the elite strikeouts of some of the top aces, he gets to pitch half his games in a spacious pitcher's park. It is possible that his struggles in September could push his ADP back a little bit as people may forget just how great he was for the first five months.

After a great half-season in 2013 followed by a gem against the Tigers in the ALDS, the hype was high for Gray heading into 2014 and all he did was live up to it. In his first full season, Gray won 14 games and put up a 3.08 ERA over 219 innings. His K/9 rate fell from 9.5 in 2013 to 7.5 in 2014, but that was somewhat expected with the large uptick in innings as the strikeouts really dropped off in the second half. Gray appeared to be tiring late in the year after entering August with an ERA of 2.65, but he seemed to find a second wind with a 2.25 ERA and nearly a strikeout per inning over his last five starts. Gray also added to his reputation as a fantastic big-game pitcher, throwing a complete game shutout gem on the final day of the regular season to get the A's into the playoffs. The sky appears to be the limit for Gray and he should be drafted even higher in 2015, especially since he gets to pitch half his games in a spacious home park.

Gray was the A's top pitching prospect coming into 2013, and he exceeded any and all expectations upon his call-up to the A's as a starter in August. He made 10 starts with the A's and won five games, while putting up a 2.85 ERA with a 9.2 K/9. He later capped off his season with an eight-inning shutout of the Tigers in Game 2 of the ALDS. Gray features a fastball that sits in the low 90s, but he also has an exceptional curveball that he uses to strike batters out. He has a rotation spot locked up in 2014, and his future appears to be quite sunny.

Gray was selected 18th overall in the 2011 draft out of Vanderbilt. In his first full season in the minors, Gray had some growing pains compiling a 4.26 ERA in 27 starts, all but one of which were in Double-A. He has a live fastball and also possesses a curveball that was ranked as the best in the 2011 draft. Gray's strikeout rate fell way off from his six-start debut in 2011 as he only struck out 5.9 K/9 in 2012. Going into last season, it was assumed that Gray would be in the A's rotation at some point in 2013, but it looks like more seasoning is in order. For his development, 2013 will be a big year for Gray to put some results together to show he was worthy of his first-round selection.

Gray was the A's first-round selection in the June draft and was immediately tasked with facing Double-A hitters following a collegiate career at Vanderbilt. His professional debut went well during a five-start stretch with Double-A Midland. He's not an imposing figure on the mound, but does a nice job of keeping the ball on the ground and figures to spend a good chunk of the season at Triple-A Sacramento after proving that he's solved Midland to begin the year.
