The Cubs have had four different closers over the last three seasons.
Beyond Aroldis Chapman, Wade Davis, Brandon Morrow and Hector Rondon, they've had a handful of other pitchers who could be "the guy" if an injury befell the back end of the team's bullpen — guys like Carl Edwards Jr. or Koji Uehara or Steve Cishek or even Justin Wilson.
Somehow, Pedro Strop always seems to get overlooked.
The 32-year-old veteran has been one of the more underrated relievers in the game since he came over as "the other guy" in the Jake Arrieta trade with the Baltimore Orioles in July 2013.
After two shutout innings Saturday in St. Louis — a ballpark and a team that has haunted him in the past (7.04 ERA, 1.76 WHIP at Busch Stadium, even after Saturday's outing) — Strop now has a 1.93 ERA and 1.07 WHIP on the 2018 campaign.
Overall, he's 16-18 with a 2.68 ERA, 1.03 WHIP and 332 strikeouts in 285.2 innings in a Cubs uniform. He has never finished a year in Chicago with an ERA above 2.91.
Since the start of the 2014 season (his first full year with the Cubs), Strop ranks 21st in baseball in ERA among relievers, just behind guys like Cody Allen and Kelvin Herrera and coming in ahead of pitchers like Roberto Osuna, David Robertson and Greg Holland. In that same span, he ranks 13th in baseball in appearances (278), more than stud relievers Kenley Jansen and Andrew Miller.
This year, Maddon is using Strop more than ever, as he's on pace for 71 innings, which would represent a career high.
Even despite the consistency and regular season numbers, Strop still found himself outside Joe Maddon's Circle of Trust during the 2016 playoff run. However, that was more due to a knee injury that sidelined him to end that regular season, leading to a bit of rust entering October.
Pitching in a Cubs uniform on the postseason over the last three years, Strop has only allowed 7 hits in 16.1 innings, sporting a 2.20 ERA and 0.80 WHIP in 19 appearances.
What's led to that consistency?
"I think it's routine," Strop said. "Be professional in what you're doing, even when the day doesn't go well for you. OK, it's in the past, keep looking ahead and just try to do better whenever you get back in there. Stuff like that.
"Little things can change the whole thing. I'm really mentally tough to walk away when things are bad. I think that's been a huge part of me being consistent — just let everything go and keep going."
Strop has admitted he hasn't always been very good at letting the bad stuff go.
The only reason he was even available in the deal five summers ago was because he had posted a 7.25 ERA in 29 games in Baltimore after looking like one of the game's bright young relief stars the previous two seasons (2.34 ERA).
Strop has spent a lot of time learning from other veterans in his career and has now gotten to the point where he's now one of the seasoned, wise vets in the Cubs bullpen, lending counsel to younger guys like Edwards.
"I've been learning a lot and I think [the mental aspect] is a really important part, especially for relievers," Strop said. "You don't have as much time to be thinking about bad outings. You just gotta put it away and get back in there the next day.
"I don't want to say starting is easier, but when you have a bad outing as a starter, you have another five days to put everything together in bullpens and stuff. But as a reliever, you gotta be ready the next day."
