The Reds added a late-inning reliever to the NL's best bullpen today, acquiring Jonathan Broxton from the Royals, according to Ken Rosenthal of FOX Sports (Twitter link). The Reds sent Triple-A lefty Donnie Joseph and Double-A righty J.C. Sulbaran to the Royals in return, tweets Rosenthal's colleague Jon Paul Morosi.

Broxton, 28, has bounced back this year to post a 2.27 ERA in 35 2/3 innings, although his peripheral stats aren't great with a 6.3 K/9 and 3.5 BB/9. He has posted a career-best 56.6% groundball rate, a large part in why he's allowed just one home run. Broxton is throwing 95 miles per hour again and has racked up 23 saves, though I'm guessing he'll join Sean Marshall in setting up Aroldis Chapman. Broxton is on a one-year deal and has $1.4MM remaining in base salary.

Joseph, 24, has a 1.72 ERA, 11.7 K/9, 2.9 BB/9, and one home run allowed in 52 1/3 relief innings across Double and Triple-A this year. Baseball America ranked him 27th among Reds prospects prior to the season, suggesting at the time he could become a power reliever in the bigs if able to improve his mechanics.

Sulbaran, 22, has a 4.04 ERA, 9.5 K/9, 4.6 BB/9, and 1.46 HR/9 in 104 2/3 innings as a starter at Double-A this year. Baseball America ranked him 12th among Reds prospects prior to the season, praising his stuff but expressing concern with his maturity and secondarypitches. They saw his future as a potential No. 3 starter at that time.
