KANSAS CITY -- Right-hander Jason Frasor has been a member of the Royals' bullpen only since the All-Star break but, oh my, has he been impressed.
"It's incredible. These guys are really, really good. I feel like I've played in a lot of good bullpens, but the arms, the velocity! And they all throw strikes with that velocity. And they all have an out pitch," Frasor said. "Ask me in a couple more weeks -- maybe it's the best I've ever been on. I want to watch them a little bit more, but it's really, really good."
No wonder Frasor has been impressed. Since the break, the Royals' bullpen has been the best in the American League. Prior to Saturday night's game against the Giants, the relief corps had an AL-low 1.52 ERA with nine saves and a 5-1 record since the Midsummer Classic.
Frasor has done his bit with 5 2/3 scoreless innings and a 2-0 record in nine appearances since being acquired from the Rangers.
For the season, the Royals' bullpen ranked fifth in the AL with a 3.24 ERA. The Mariners were first at 2.35, followed by the A's at 2.76, the Indians at 3.00 and the Orioles at 3.22.
Manager Ned Yost has settled into a regular routine with Kelvin Herrera pitching the seventh, Wade Davis the eighth and Greg Holland the ninth. But he's also got other options.
"We've got so much depth down there," Yost said. "You can pitch Aaron Crow, Herrera in the eighth or ninth. Frasor, a veteran guy who comes in and throws strikes, can pitch in the eighth or ninth inning on a day when Wade or Holly aren't available."
Also in the 'pen are veterans Bruce Chen, Francisley Bueno and Scott Downs, all lefties.
"I try to milk every pitch I can out of my starters so we can reduce the pitch load of the bullpen on the back end of it. Our bullpen guys have done a great job," Yost said.
The back-end trio of Herrera, Davis and Holland are wowing opponents with their wicked fastballs, too.
"Me, Downs and Chen -- we're slopping it up there compared to these guys," Frasor said.
