Since we focused on the offensive side last week when listing the Top 10 in active OPS in Major League Baseball, this week we’ll take a look at the active WHIP leaders for pitchers. That stands for Walks plus Hits per Inning Pitched, and is an extremely important statistic when you’re considering pitchers to draft for your fantasy team. Not only do most fantasy leagues count points for WHIP, but it’s a great indicator of overall pitching prowess. Here is that Top 10 in WHIP, and it includes only pitchers who are active going into the 2009 season:

1. Mariano Rivera, New York Yankees (1.0199)—Rivera has been the hammer in the Yankees’ bullpen for over a decade and still shows no signs of slowing down. At the age of 38 in 2008, Mo struck out 77 in 70 innings, and racked up 39 saves.

2. Pedro Martinez, free agent (1.0512)—True, Pedro is about a lifetime removed from his dominating days with the Red Sox, but dude can still pitch effectively and has no MLB team at the moment.

3. Johan Santana, New York Mets (1.1024)—Will Johan be the guy to lead the Mets to their first title in almost 25 years? He had a brilliant first season in New York but was hurt by lousy run support and an even lousier bullpen.

4. Curt Schilling, Boston Red Sox (1.1374)—It’s hard to believe Schilling is not done yet, because he hasn’t pitched in a real game in almost two years. But if and when he goes back out there, I’m still picking him for my fantasy team.

5. Randy Johnson, San Francisco Giants (1.1673)—The Big Unit is five wins shy of 300 for his career, and reaching 300 is something that seemed impossible when he had back surgery before last season. But dude is still a beast and still blowing the ball past hitters, and he’s in his mid-40’s.

6. John Smoltz, Boston Red Sox (1.1697)—It’s going to be strange seeing Smoltz in a Red Sox uniform, but as a diehard Mets’ fan, I couldn’t be happier about that.

7. Jake Peavy, San Diego Padres (1.1864)—When you think of the game’s top pitchers, do you think of this dude? Well, you should. Peavy has already racked up 1256 strikeouts and he’s only 27.

8. Roy Oswalt, Houston Astros (1.1979)—Another amazing young pitcher, Oswalt is 31 years old and has a lifetime record of 129-64 for a usually-less-than-awesome Astros’ team. That’s just sick.

9. Ben Sheets, free agent (1.2010)—If he ever pitched a full season, Sheets would be a lock for the Hall of Fame by now. But you just never see an injury report without his name on it.

10. Roy Halladay, Toronto Blue Jays (1.2076)—Playing north of the border, Halladay has won the AL Cy Young Award once and finished in the top 5 in voting three other times. How have the Yankees kept their paws off of this guy?
