The Numbers: It's been awhile since Mo Rivera allowed a granny

Each week, Big League Stew stat doctor Alex Remington will bring you a few baseball numbers you need to know.

The number of games that Mariano Rivera(notes) went without allowing a grand slam until Jason Kubel(notes) hit one against him on Sunday. It was the first home run Rivera had given up all year and was his first surrendered slam since Cleveland's Bill Selby — remember him? no? — hit one in 2002. It also broke a personal 18-game homerless streak.

The number of times, as pointed out by Baseball Reference, that Mo has given up two or more runs while recording two outs. And that's from a sample size of 930 regular-season appearances during his 15-year career. Can you say consistent?

The percentage of save opportunities that the Milwaukee Brewers have managed to convert. The Brew Crew have more saves blown than wins saved; five saves in 12 opportunities. But they're not the only team below 50 percent: The Mets are 8-for-14, and the Diamondbacks are 9-for-16. The Mets have been a bit unlucky: Francisco Rodriguez has only been scored upon in three of his 17 appearances, but he's wound up with two blown saves and a loss. But Trevor Hoffman(notes) (11.08 ERA, four blown) and Chad Qualls(notes) (7.62 ERA, three blown) probably shouldn't be handed the ball in the ninth any more.

The number of games that the Kansas City Royals have gone without a grand slam, most in the majors. The previous streak was the Atlanta Braves' 253, from July 25, 2008 to May 10, 2010, snapped when Martin Prado(notes) connected off the Brewers' hapless Manny Parra(notes) last week.

The number of American League teams that have received worse DH production than the Tampa Bay Rays, which designated Pat Burrell(notes) for assignment on Saturday. The Rays' DH spot has been helped by Willy Aybar's(notes) 55 PA with a .781 OPS. But Burrell's hardly the only veteran DH to suffer this year. Hideki Matsui(notes) and his .239 BA have hardly been worth his $6 million; Juan Pierre(notes), Carlos Quentin(notes) and Mark Kotsay(notes) have been awful in Chicago's ineffective DH platoon; Ken Griffey's troubles in Seattle have been well-documented; and Eric Chavez(notes) may be finished as a major leaguer. The Rays' quick trigger on Burrell was justified, now other teams have to ask themselves how soon they're willing to follow suit.

The percentage of would-be basestealers that Yadier Molina(notes) has thrown out; nine out of 15 attempts. The surprising Miguel Olivo(notes) is the only other catcher who's caught more than he's allowed, 13-of-22. (Olivo, who's had a hot bat this year, has each of the last two perfect five-hit games by a catcher, going 5-for-5 on May 12 of this year and June 16 of 2007.)

Nyjer Morgan's(notes) major league leading caught stealing total. Morgan is a terrific defensive outfielder and a useful hitter, but he's always been a little prone to getting nabbed on the basepaths. Still, he's rarely this bad. Last year, he was 42-for-59; this year he's 8-for-16, and a big reason that the Nationals are tied with the Texas Rangers for most times caught stealing as a team, with 16. The Nationals don't have enough offense to compensate for all those outs they're giving up. (Jim Riggleman is no stranger to poor stolen base totals, though. His last NL team, the 1999 Chicago Cubs, was only successful on 60 of 104 attempts. That wasn't the only reason those Cubs finished last, but it surely didn't help.)

The number of weeks that this column has noted that Andre Ethier(notes) is leading the National League in batting average and RBIs, and is tied for the league lead in homers. Sadly, the streak will likely end here as Ethier suffered a broken bone in his right pinky during batting practice on Saturday and will probably miss a few games as the Dodgers evaluate whether or not he needs to hit the DL.
