He spent most of the year at Triple-A, and walked more batters than he struck out in 10.1 innings with the Rockies, resulting in his designation for assignment last week. The Cubs will take Brothers on as a low-cost reclamation project, but unless the lefty is able to cut down significantly on the free passes, he will have a tough time earning and maintaining a role with the big club in 2016.
Webster, who was DFA'd by the Diamondbacks in November, dealt with shoulder fatigue early in the 2015 season, but he was given an opportunity to make a few starts in June. However, he allowed 15 earned runs over four starts, earning a trip back to the minors before returning to the big league club as a bullpen option later in the year. The 25-year-old will join Pittsburgh's 40-man roster, which is now at capacity.
Pimentel appeared in eight games for the Rangers last season, putting together a 3.97 ERA and 1.24 WHIP in 11.1 innings. Including this season, the 25-year-old right-hander has appeared in the majors every season since 2013, but he's failed to record more than 20 appearances with each club -- thus limiting Pimentel's role to mere organizational depth with the Mets.
The Diamondbacks were able to avoid arbitration and sign Reynolds to another year. Reynolds was brought up to the majors at the end of August to pitch out of the bullpen, and will battle for a spot on the opening day roster.
Carpenter had a short stint with the Nationals cut short by a shoulder injury, which likely scared many teams away from offering him a 40-man spot, especially when his mediocre 3.68 ERA takes the reward away from the risk. His velocity also cratered in July while playing through inflammation in that shoulder. He'll need to show his old stuff in spring training before anyone is ready to give him his old set-up role.
While Okert took a step back with his control in 2015, issuing 29 walks in 61.1 innings, he showed the Giants enough to warrant protection from the Rule 5 draft. He struck batters out at a 10.1 K/9 clip and posted a 1.26 ERA in 10 appearances in August.
Viewed by some as a top-50 overall prospect a few short years ago, Crick has only further regressed with his control issues, allowing a total of 127 walks over the last two seasons with Double-A Richmond. He was moved to the bullpen full-time in July, and he has the swing-and-miss stuff to ultimately succeed, but Crick must limit the walks before he gets a major-league opportunity.
The 25-year-old missed the cut out of camp, and battled shoulder fatigue in the early months of the season, but he got a chance in June when Josh Collmenter was bounced from the rotation. Webster did not fare well, allowing 15 earned runs in four starts, and later served primarily in a bullpen role after another stint in the minors. His 40-man spot was needed to protect a prospect from the Rule 5 draft.
The move was for Rule 5 protection, but Barrett could be contributing out of Arizona's bullpen sometime in 2016, possibly in semi-high leverage spots, given the fact that he has been a closer at most of his stops in the minor leagues.
Johnson may be the closest to the big leagues of the Cubs' noteworthy pitching prospects. However, this move was primarily for Rule 5 protection. Look for Johnson to spend most of 2016 at Triple-A, and possibly slot into the big league rotation if there is a need in the second half.
