The 30-year-old received a major-league contract but will take a steep pay cut after making $8.8 million last season. Norris was clobbered to the tune of a 7.06 ERA in 18 appearances (11 starts) for the Orioles last season before being released, and then pitched exclusively out of the bullpen after signing with the Padres in August. It's uncertain what role he will take on with Atlanta, but it's at least possible he could return to the rotation for the rebuilding Braves.
The No. 2 overall pick in the 2011 draft, he is out of options and coming of a 2015 season plagued by shoulder issues, so it's not much of a surprise that the lefty went unclaimed on waivers. Hultzen will remain in the Mariners' organization at least through 2017, after which he can become a minor league free agent if he's not on the 40-man roster.
Griffin, who underwent Tommy John surgery in April of 2014, appeared in just four games for the A's minor-league affiliates this season, before finding the sidelines due to a shoulder strain. The 27-year-old did post multiple positive seasons with Oakland in 2012 and 2013, so it seems likely he could sign a minor league contract with another team provided he's healthy, but it's unlikely Griffin will provide much at the major-league level this season.
This probably won't directly improve anything other than the young pitcher's style, but there are reasons to be bullish on him heading into 2016. Much has been made about the Orioles mishandling the talented righty, but that won't be an option next year, as Gausman is basically a lock to be in the rotation all year. He averaged 95.2 mph on his fastball in 2015, and still has the overall repertoire to be at least a No. 3 starter.
Diamond recorded a 3.71 ERA and 1.37 WHIP with Triple-A Durham last season and has posted time with the Twins in 2011, 2012 and 2013. The 29-year-old is expected to provide some organizational depth, but he likely won't contribute much at the major league level.
Paxton threw seven simulated innings Monday and will do so again later this week before shutting down for spring training. Among his 13 starts in 2015, seven went at least six innings, while only three reached the seven-inning threshold, which the aforementioned regimen is attempting to remedy as a part of the Mariners' rotation.
Aumont once rated as a top-100 prospect and was included in a Clif Lee trade, but he has yet to do much in his 46 career major league appearances, and he did nil in the Blue Jays' organization after signing mid-2015. He will attempt to resurrect his career in a White Sox's organization that has previously revived previously-heralded arms.
Hellweg spent the 2015 season in the Brewers' minor league system and was his first year coming off of Tommy John surgery. He became a free agent this offseason and has decided to sign with San Diego, where he will try to climb his way through their minor leagues in 2016.
The 21-year-old signed for $2.6 million as a 17-year-old out of Mexico in 2010. He's struggled with his weight and registered a 5.44 ERA and 1.73 WHIP in 86 innings for High-A Bradenton in 2015. At 21, Heredia still has a chance to turn his career around but it might not be with Pittsburgh.
The strikeout rates have fallen as Stratton has moved up the ladder, dropping to 6.6 K/9 with the move to Triple-A Sacramento in 2015. Stratton was able to enjoy some success last season, regardless, posting a respectable 3.86 ERA and 1.31 WHIP over 17 starts for Sacramento. He figures to be a spot-start option for the big club in 2016.
