The 22-year-old started 22 games for High-A Bakersfield in the Mariners organization, posting a 4.01 ERA and a 9.6 K/9. Pike's strikeout ability is certainly intriguing, but his lack of control could keep him from advancing much farther in the organization.
Jenkins finished with seven more walks than strikeouts (26:33 K:BB) in 52 innings with the Braves in 2016, and was hit hard when he did put the ball in the strike zone (11 homers). His 5.88 ERA looks bad enough, but his FIP was almost a full run higher at 6.86. The right-hander also battled some ulnar nerve inflammation late in the year, which caused some numbness in his fingers. It's uncertain how he'll be deployed to begin 2017, but Jenkins seems destined to end up in the bullpen full time.
Sanchez has been putting in the extra work at the Jays' Dunedin complex. Through the workouts, the 24-year-old has reportedly improved his vertical jump, range of motion and power. Sanchez put in similar efforts last offseason, and that was rewarded with a career year in 2016 that ended with a seventh-place finish in the AL Cy Young voting.
The 25-year-old southpaw split time between the Phillies and Royals systems last year, failing to make much of an imprint in either organization. He posted a 2.11 ERA and 26:4 K:BB in 21.1 innings at Double-A for the Royals, but was left unprotected, suggesting that his upside is limited. The Tigers will need to keep him on the active roster all season, otherwise he will be subjected to waivers and offered back to the Royals. Look for him to work out of the bullpen in extremely low-leverage situations.
Covey has back-of-the-rotation upside, but he is not ready to turn over a big league lineup. The 25-year-old righty has just 29.1 innings of experience above High-A, and while his 1.84 ERA looks nice, he posted an ugly 26:17 K:BB in that span. The White Sox will need to keep him on the active roster all season, otherwise he will be exposed to waivers and offered back to the A's. An oblique injury ended his 2016 season in May, but he should be ready for the start of spring training. Look for Covey to be used occasionally as a mop-up man in 2017.
The right-hander had the procedure in early May, which may keep him out of the mix for a rotation spot in Oakland until the second half of 2017. Bassitt had some success in 2015 with the A's when he piled up 86 innings over 18 appearances (13 starts) and pitched to a 3.56 ERA, and the organizational need for arms capable of starting should keep the door open for him to remain a starter once he's healthy enough to get back on the mound.
To date, everything seems to be going as planned for Richards' recovery from a torn UCL, as he opted for stem-cell therapy instead of Tommy John surgery. Richards was one of several Angels pitchers to succumb to an arm injury in 2016, but Scioscia indicated that there won't be any revisions to the team's program during spring training.
Considering the Giants may have left Heston off the 40-man roster to accommodate Mark Melancon, it is not surprising that it only required a PTBNL for the Mariners to net the 28-year-old righty. Heston may be behind Nate Karns and Ariel Miranda in the pecking order for the fourth and fifth starter spots in Seattle, but he has a better chance of eventually joining that rotation than if he had remained in the Giants' system. He has a career 4.04 FIP, 1.37 WHIP and 148 strikeouts in 188 big league innings, mostly working as a starter. An oblique injury ended his 2016 season, but he should be recovered by the time spring training rolls around.
He had moments of brilliance after being promoted to the big leagues last year, particularly dominating the Braves in a couple starts. However, it remains to be seen whether Lopez is a starter or reliever long term. A 6-foot righty, Lopez he has a lot in common with Yordano Ventura, where an 80-grade fastball helps the rest of the repertoire play up, but shaky command could limit his effectiveness in the rotation. The White Sox will undoubtedly develop Lopez as a starter, making this a win for his dynasty league owners, as the Nationals may have been able to make better use of him in the bullpen. He could be a No. 3 or No. 4 starter who strikes out a batter per inning but posts a below-average WHIP. If that does not work out, he could be a legitimate ninth inning arm. Lucas Giolito and Dane Dunning were also a part of Chicago's haul.
Giolito's prospect star has faded slightly, as he entered 2016 as the top pitching prospect in the game, and is no longer a top-10 prospect for fantasy purposes. His fastball velocity and command both took a step back last season, as he averaged just 93.3 mph on his heater and posted an 11:12 K:BB in 21.1 innings in the majors. If his fastball velocity can rebound, which is possible, he still has the other ingredients to become a frontline starter, with a curveball that flashes plus-plus and a changeup that flashes above average. While he has Tommy John surgery on his resume, he also has the size (6-foot-6, 255 pounds) to eventually log 200-plus innings annually. For immediate fantasy purposes, this is a boon for Giolito's owners, as he did not have an obvious path into the Nationals' rotation, and should be a part of the White Sox's rotation in short order, possibly at the start of this season. He will also get to work with respected pitching coach Don Cooper. Reynaldo Lopez and Dane Dunning rounded out the return package for Chicago.
