JUPITER, Fla. -- Cardinals manager Mike Matheny knows that he has one of the best closers in the game in right-hander Trevor Rosenthal, who registered a franchise single-season record 48 saves and posted a 2.10 ERA last season.
Matheny also believes the rest of the bullpen is capable of complementing Rosenthal very nicely in 2016.
"It's a huge position and only so many guys can do that," Matheny said of the closer's role before Sunday's workouts at the Roger Dean Stadium complex. "Trevor has done a great job of it. Great season last year, very impressive. In the meanwhile, looks like we have some really good options [as setup relievers]."

At the top of the list is lefty Kevin Siegrist, who went 7-1 with a 2.17 ERA and 90 strikeouts in 74 2/3 innings last season. Matheny likes the progress he has seen in Siegrist.
"We've seen so much consistency," Matheny said. "We've seen how good he can be late in the game, and we've given him opportunities to close it out."
The Cardinals were looking for more depth in their bullpen during the offseason and addressed that by signing two veterans in Korean free-agent right-hander Seung Hwan Oh and right-hander Jonathan Broxton, a former closer who spent the last two months of last season with the Cardinals after coming over in a trade with the Brewers in late July.

"We know Broxton can [close]," Matheny said. "We know [Jordan] Walden can do that. We know Oh has done that overseas, and we're anxious to see how he handles whatever role. All those guys combined give us some flexibility to maybe give Trevor a rest."
There are a handful of others who could also add to the bullpen's depth, including right-hander Seth Maness, who appeared in 76 games last season, and Miguel Socolovich, who along with Carlos Villanueva (now with the Padres) provided some key innings in 2015.
"Miguel and Carlos Villanueva were good for us in so many ways," Matheny said. "I think we have some guys on this club that can fill that role, multiple roles. It's a great problem to have, all the competition to see where they fit the puzzle."

One thing is certain as Grapefruit League games begin later this week: There is no competition for the role of closer in St. Louis. That belongs to No. 44.
"His repertoire is getting bigger and better," Matheny said of the 25-year-old Rosenthal, who threw live batting practice on Sunday. "Where he's using the breaking ball, he's using the changeup. I think he's his own guy. Can't compare to anyone else, really."
