Wilson spent the offseason making an adjustment to his delivery, which now includes a lower leg kick when he finishes his pitches, Carrie Muskat of MLB.com reports. "[Wilson] made an adjustment and the adjustment that he made, he understands the importance of strike throwing in his delivery," manager Joe Maddon said. "In a perverse way, it was not good but he figured something out mechanically or physically that I think long term will benefit him."

EDGE Analysis

Wilson helped stabilize a porous Tigers bullpen in the first half of last season, displacing Francisco Rodriguez as closer in early May and registering a 2.68 ERA, 13 saves and a 55:16 K:BB in 40.1 innings over 42 appearances before being dealt to the Cubs on July 31. The lefty moved down a few rungs in the comparatively deeper Cubs bullpen and was never able to find his footing with his new team. He posted a 5.09 ERA in 23 outings with Chicago, which resulted in him being left off the team's NLCS roster. The poor finish to last season will likely result in Wilson settling for middle-relief work to begin the upcoming campaign, but if the offseason adjustment helps the 30-year-old rediscover the form he previously displayed with the Tigers, he could ultimately settle into a more prominent setup role.

Wilson agreed to a one-year, $4.25 million deal with the Cubs on Friday, avoiding arbitration, Gordon Wittenmyer of the Chicago Sun-Times reports.

EDGE Analysis

This is Wilson's final year of arbitration before he hits the open market next winter. He notched a 2.68 ERA, 55 strikeouts and 13 saves in 40.1 innings with the Tigers before he was traded to Chicago last summer, but was surprisingly much less successful in the National League. Wilson sported a 5.09 ERA in 17.2 innings with the Cubs, and was not reliable in high-leverage spots. His past success as a closer means that he could someday get save chances again, but he figures to enter this season behind Brandon Morrow, Carl Edwards, Pedro Strop and possibly Steve Cishek in the bullpen hierarchy.

Wilson is not on the NLCS roster for the series against the Dodgers.

EDGE Analysis

Wilson only pitched once during the NLDS against Washington, recording two outs during Wednesday's Game 4 loss. He was replaced on the active roster by Hector Rondon, but could rejoin the 25-man for the World Series were the Cubs to advance.

Wilson is dealing with a sore neck, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

He says the neck issues did not contribute to his struggles Tuesday (two walks, zero outs). It is unclear when Wilson will next pitch out of the bullpen, but the Cubs will want to make sure he is right heading into the postseason.

Wilson pitched 1.1 perfect innings in Saturday's loss to the Brewers and struck out three.

EDGE Analysis

It's been a rough go for Wilson since coming over to the Cubs before the July 31 trade deadline, and he's been particularly bad this month with an 11.57 ERA over 4.2 innings even after Saturday's strong outing. The Cubs could really benefit from Wilson establishing himself as a trusted left-handed reliever, but time is running out on the regular season and it's hard to see the team being too patient if Wilson struggles in the postseason.

Wilson is aiming to pitch better and prove himself capable of a high-leverage role as the postseason approaches, Steve Greenberg of The Chicago Sun-Times reports.

EDGE Analysis

Wilson has mainly struggled with the Cubs since coming over before the July 31 trade deadline, as he's posted a 6.23 ERA and 2.15 WHIP in 13 innings with his new team. But manager Joe Maddon noted that Wilson could still play a key role for the team late in games. "Man, he could be the linchpin of a lot of this stuff right here," Maddon said. "If we get this guy right, that could make a big difference down the stretch run and hopefully into the playoffs."

Wilson struck out all three batters he faced in Thursday's win over the Braves.

EDGE Analysis

Wilson came on in the ninth inning with the Cubs up 6-2 and he mowed down the Braves on 22 pitches (16 strikes). Wilson struggled out of the gate with his new team, but he hasn't allowed a run over his last six appearances (5.2 innings) and he looks like he'll be a key contributor to the Cubs bullpen as they make a push for the playoffs.

Wilson (4-4) recorded the win Sunday against the Blue Jays by retiring a single hitter. He walked two batters as well.

EDGE Analysis

Wilson came on in the top of the 10th with two out and runners on second and third. He promptly walked two straight batters, which scored a run to make it 5-3 Toronto, before retiring the final batter on a fly to center. Though he wasn't overly effective, Wilson grabbed the win when the Cubs scored three runs in the bottom of the inning. Overall, Wilson has a weak 6.35 ERA and 3.18 WHIP in eight games (5.2 innings) with his new team.

Wilson recorded a blown save, his first with the Cubs, in Thursday's loss to the Diamondbacks. He allowed two inherited runners to score in an inning of work.

EDGE Analysis

Wilson wasn't tagged with any earned runs, but he wasn't overly effective in this one. After Carl Edwards walked the first two batters of the inning, Wilson was summoned to face Brandon Drury, who promptly singled to load the bases. Jake Lamb followed with another single to score two runs. Wilson was able to escape without further damage, however. He hasn't been great so far with his new team, as he allowed a run on two walks and a hit in his debut Wednesday, and the Cubs are hoping for better results moving forward.

Wilson has been traded to the Cubs along with Alex Avila in exchange for Jeimer Candelario, Isaac Paredes and either a player-to-be-named-later or cash, Lynn Henning reports.

EDGE Analysis

Wilson goes to a team that won't use him as a closer, at least not for this year. But the Cubs still can give him plenty of high-leverage outings and have him potentially close in 2018 and beyond.
