It’s mid-May, with the baseball season being nearly a quarter of the way through.  As teams approach the 40-game mark, it’s the St. Louis Cardinals that own the best record in baseball and top spot in the MLB Power Rankings.

On the other side of the spectrum, the Marlins and Astros continue to be the league doormats, while the Angels, Dodgers and Blue Jays maintain a stranglehold on the award as the baseball’s biggest disappointments.

In KP’s latest edition of MLB Power Rankings at The Wife Hates Sports, the aforementioned Cardinals sit in first place, followed by the Detroit Tigers and Texas Rangers.  A pair of American League East teams – the New York Yankees and Baltimore Orioles – round out the top five.

The entire list of power rankings is as follows, featuring some specific team and player related statistics, or in some cases, other random notes and tidbits:

KP’s MLB Power Rankings: May 14, 2013

Note: Statistics and point totals as of Tuesday morning (5/14/13) and do not include night games

1. St. Louis Cardinals (119 points)

The Cardinals have the best record in baseball, which is one reason for the top ranking.  The team’s 3.03 team ERA (three-tenths better than any other team) is another key to this position.

2. Detroit Tigers (109 points)

Detroit’s combined batting and pitching rating value is the best in baseball.  Combine that with an MLB-best +58 run differential, and the Tigers jumped up to the second spot this week.

3. Texas Rangers (108 points)

Adrian Beltre’s bat is heating up, as the third basemen is hitting .327 over the last 15 days, with 4 home runs, 3 doubles and 14 RBI during that span.

4. New York Yankees (93 points)

Hiroki Kuroda has been the most consistent starter in New York’s rotation, posting a 5-2 record, with six quality starts, a 2.31 ERA and 1.05 WHIP.

5. Baltimore Orioles (85 points)

20-year-old Manny Machado is thriving in the two-hole, batting .331, with five HR, 14 doubles and 24 RBI over 38 games played.

Sparked by a recent hot streak, it’s a safe bet to put manager Terry Francona as the current front runner for Manager of the Year in the American League.

19. Oakland Athletics (8 points)

20. Seattle Mariners (3 points)

In his first season with the Mariners, Michael Morse has 9 HR in 32 games, but his average (.230) and RBI total (15) have been lacking.
