Pomeranz had already thrown a major-league-high 102 innings with the Padres before the Red Sox acquired the left-hander at the trade deadline. He made 13 starts after the trade, posting a 4.68 ERA while giving up 14 homers and averaging just 5.2 innings per start. Pomeranz had a nice seven-start stretch mixed in with his short outings and a bout of forearm soreness that bumped him from the rotation in late September. There was likely an element of dead arm late in the season, as he was reaching uncharted territory in innings pitched. He was evaluated after the season and everything came back clean. Pomeranz will be ready for spring training, and considering what the Red Sox gave up to get him, he should be given every opportunity to prove he belongs in the rotation. There is plenty of upside on a per-inning basis, but he may not go deep into games, and last season was the only time he has topped 150 innings in a season as a pro.

Pomeranz started the season in the rotation after winning a spot during the spring, but he headed to the disabled list after only eight starts. He only spent two weeks on the DL, but when he returned he was moved to the bullpen (he only started one more game the rest of the season) and even found his way in the closer mix earning two saves in August after the A's traded Tyler Clippard. For the second straight year, Pomeranz was better out of the bullpen and may have found himself a nice role going forward. The lefty had a 4.63 ERA in his 44.2 innings as a starter with a 7.3 K/9, but sparkled in his 41.1 relief innings with a 2.61 ERA and a 10.0 K/9. He was particularly nasty against lefties in 2015, allowing a paltry .438 OPS to lefties over 99 at-bats. The A's traded him to the Padres in the offseason and it's not clear if he'll stay in the bullpen or move to the rotation with the Padres, but he could provide fantasy value if he continues the success he's had as a reliever.

The A's acquired the former first-round pick from the Rockies for Brett Anderson in the offseason and he responded with a very solid season. Pomeranz started the year working out of the A's bullpen, but he was pressed into starting duty in May. He spent approximately six weeks in the rotation, allowing two runs or fewer in six of his eight starts, before breaking his right hand punching a chair after a poor outing against the Rangers. After the injury had healed, the A's had traded for a few starters and he spent the rest of the year starting in Sacramento, except for a couple of spot starts with the A's during the second half. Overall, Pomeranz put up a 2.58 ERA as a starter with a strong 8.6 K/9 rate. Pomeranz has a shot to win a job in the A's rotation to start the year, especially with Jarrod Parker and A.J. Griffin returning from Tommy John surgery and likely to be unavailable to begin the 2015 season.

The Rockies have given Pomeranz every opportunity to clamp down a permanent rotation spot in each of the past two seasons, but despite his top-notch pedigree, he’s failed to develop into a remotely capable big league starter. In fact, the 2013 season arguably represented a step back for Pomeranz, who was sub-replacement level in his eight appearances (four starts) with the Rockies, posting a 6.23 ERA and unsightly 7.9 BB/9 rate. Control issues have dogged the lefty as he’s advanced through the system, though he did negotiate the strike zone better in his four September appearances out of the bullpen. Seeking a more established veteran for the rotation, the Rockies traded Pomeranz to the A's in December for Brett Anderson, where it's expected that Pomeranz will attempt to secure the final spot in the Oakland rotation during spring training.

Pomeranz's rookie campaign was mostly forgettable, as the young lefty's inability to command his secondary pitches resulted in a 4.3 BB/9. When he did find the strike zone, Pomeranz was either not whiffing batters as often as anticipated (7.7 K/9) or getting taken yard (13.6% HR/FB rate). With the Rockies returning to a traditional five-man rotation with pitchers expected to be held between 90 and 100 pitches each outing, Pomeranz should at least get more innings and wins under his belt since high pitch counts usually chased him from games prematurely last season once the rotation moved to a roughly 75-pitch limit per start. Pomeranz's three-pitch repertoire arguably gives him the best pure stuff among the team's pitching staff, but he will need to demonstrate greater control to make good on his considerable potential, especially at a place like Coors Field.

Pomeranz was the centerpiece of the blockbuster deal that sent Ubaldo Jimenez to the Indians last season, and he managed to make four big league starts in September after opening the year at High-A Kinston. Considering that he finished his college career at Ole Miss as a polished left-hander with a low-to-mid-90s fastball, plus-curveball and change-up, the fast track shouldn't come as much of a surprise. Pomeranz projects as an eventual strikeout-per-inning starter, and at age 23 he could break spring training with a rotation spot for the Rockies. Even if the Rockies send him to Triple-A for additional seasoning, he'll likely be in the big leagues for good before the All-Star break.

The Indians selected Pomeranz fifth overall in the 2010 amateur draft, but he didn't sign until the August deadline and was unable to make a professional debut last season. He already has two very good offerings in a low-90s fastball and a knuckle-curve. His control is still a work in progress, but he has the ability to miss a lot of bats and develop into a potential No. 1 or No. 2 starter if he's able to polish up a third offering -- likely a changeup -- in his arsenal. Pomeranz may pitch as high as Double-A this season, and with reasonable progression could reach the Indians' rotation at some point in 2012.
