Here's the thing: There are a lot of good relief duos out there. Eric Karabell and myself discuss five of the best ones in the video, but there are others we left out:
--The Pirates. Closer Jason Grilli is out right now, but he and Mark Melancon have been terrific all season. Melancon (0.91 ERA) has stepped into the closer's role with Justin Wilson (2.05 ERA) handling most of the eighth-inning duties. That's still a great pair, with Melancon arguably the most valuable reliever in the majors this season.
--The Rangers. They have the fourth-best bullpen ERA in the majors and are 65-3 when leading after seven innings. Great depth behind Joe Nathan with Neal Cotts, Tanner Scheppers, Robbie Ross and Jason Frasor, all with ERAs under 2.70 in 40-plus innings.
--The Royals. The second-best bullpen ERA behind the Braves, and closer Greg Holland has a 1.41 ERA and 29 consecutive saves converted, but the setup guys have been inconsistent and they have five losses when leading entering the eighth.
--The A's. Grant Balfour has just two saves all season, but the second one was a big one on Thursday afternoon, allowing four runs as the Tigers beat the A's 7-6 in dramatic fashion.
One team not listed: The Reds. Aroldis Chapman been shaky at times -- he's 3-5 with a 2.87 ERA and five blown saves -- and the Reds have lost eight games they led entering the eighth and three entering the ninth, making their bullpen one of the league's least effective in terms of holding leads late in games.
By the way, another reminder of the volatility of relief pitchers and bullpens in general: Three of the five closers included in the poll did not begin the season as their team's closer.
