Brian Duensing isn't the marquee pitcher Cubs fans were hoping their team would sign on the morning of Jan. 17, but he is one of the heroes they need.
Duensing is back in the Cubs' bullpen for the next two years at a discount of $7 million. It's a raise for him — he made $2 million in 2017 — but he left a lot of money on the table, joining players like Ben Zobrist who signed for less.
The veteran lefty was somebody the Cubs' "Geek Squad" and scouting department targeted last winter and made a priority to sign a year ago.
That worked out awfully well, as the 34-year-old Duensing put up the best season of his life with a 2.74 ERA, 1.22 WHIP and struck out a career-high 8.8 batters per nine innings.
Even Duensing himself was surprised by the strikeout totals:
"A lot of swings and misses — I don't know what that's about, to be honest," Duensing said back in August when he joined the Cubs Talk Podcast. "I really don't know what's going on there. Just things are working really well right now and hopefully they continue."
Duensing's success didn't quite continue on a linear path from there, as he followed up a stellar August (1.93 ERA) with a 4.82 ERA and 1.82 WHIP in September while striking out only six batters in 9.1 innings.
That poor last month was part of the reason why Duensing fell out of Joe Maddon's circle of trust entering the postseason, and while the veteran southpaw put up a 1.69 ERA and allowed just five baserunners in 5.1 innings, he didn't pitch often in high-leverage situations in October.
As for where Duensing fits in the Cubs bullpen in 2018 and 2019, he provides another reliable arm and helps work toward the front office's goal of getting more strike-throwers in a bullpen that struggled in that department in 2017.
Duensing walked just 18 batters in 62.1 innings and was not a part of the overall problem that saw the Cubs' bullpen post one of the worst BB/9 rates in Major League Baseball.
Of Duensing's 68 appearances in 2017, 15 of them went for more than three outs. While he wasn't a true long-relief option like Mike Montgomery, the former Minnesota Twin does have a background as a starter and can help eat up innings if a Cubs starter is knocked out early or the other bullpen arms need a rest.
He also provides another left-handed option for the 'pen with Justin Wilson a major question mark after his struggles in Chicago and Montgomery currently slotted in as a starter and expected to serve in a swingman capacity for parts of 2018. Reliable left-handed relievers are in short supply in the majors, and the Cubs are investing as much capital as they can in their bullpen.
Duensing probably isn't a guy that would fill in at closer at all if Brandon Morrow is injured or ineffective — Duensing has just two career saves — but he's another glue guy to a bullpen that looks like this:
Carl Edwards Jr.
Another arm — whether that's Montgomery or somebody else — should slot in there by the end of spring training as the Cubs are expected to roll with eight arms in their bullpen for much of the season.
The big question with Duensing is how he'll be used in October, assuming the Cubs make it there again. Maddon's bullpen usage in the postseason has been oft-questioned, but he clearly saw something in Duensing that made him lose trust on the game's biggest stage.
Does that happen again in 2018?
