Brown out: Emil Brown missed his second start with back spasms on Friday night. Shane Costa started in left field in Brown's place.
"It's OK, but I don't know if he is available [Friday] or not," Bell said. "We are waiting to see if he can be available [Saturday] or Sunday."
Bell said Brown will not be put on the 15-day disabled list.
"It's not chronic, but it is something that he has dealt with before and it usually doesn't take him that long to get through it," Bell said.
Riske excelling: After a poor April, David Riske has become one of the best relievers in baseball during May. Riske posted a 6.97 ERA in April, but hasn't been scored upon in 12 appearances this month.
The veteran right-hander encounters the same problem every year, but fixes it by watching video.
"My arm slot was off a little bit earlier in the year and I just kind of found it," he said. "It was out a little bit and when it is out, the hitters pick it up really easily. When it is going good, it is all off deception and it's hard for them to pick up the ball."
In his career, Riske has posted a 5.40 ERA in the season's first month, nearly two runs higher than his second-worst month (September, 3.43).
"When it doesn't feel right for awhile, then I can kind of look for it and try to figure out where it feels right and get that feeling back," he said. "I go through it every single year and feel something -- I don't know whether I get tired after Spring Training or what it is, but I will lose it and then I will find it again."
Team better in pressure situations: Earlier this season, general manager Dayton Moore and Bell said the offense needed to improve with runners with scoring position. Entering Friday night, the Royals ranked fifth in the American League in on-base plus slugging percentage (OPS) with runners in scoring position (.777).
"I think so," Bell said when asked if the team is better in such situations. "We have had more opportunities, and the more opportunities you have with runners in scoring position, obviously, the more experience you have at it. If you get one or two executions, you get some confidence with guys in scoring position and you get it done, it makes things easier and you are a lot more relaxed. But I still think we need to do better, I really do."
Bell said the team needs to focus on putting the ball in play in RBI chances. The team ranks third in the American League in most strikeouts (96) in RISP situations.
"For whatever reason, [striking out] has just become OK," Bell said. "You don't want to go up there worrying about striking out, but when you get to two strikes, you should still battle your way through the at-bat. I think we have done a better job at that and getting after the first couple pitches of an at-bat. We are ready to hit every pitch, and I think that has more to do with it than anything."
O'Neil seat: Larry Moore of Kansas City, Mo., sat in the Buck O'Neil Legacy Seat on Friday night. Moore, the longtime anchor for KMBC-TV news, is involved in volunteer and fundraising efforts for many organizations.
