We’re about 40% through the current major league baseball season. That means we’re about to enter the warmest part of the season both on the field and in the standings. Contenders will begin to emerge and pretenders will begin to fade if they haven’t faded already. So we thought it was a good time to have our first installment of MLB power rankings…..

1. Tampa Bay Rays (41-26)—Amazingly, the Rays have a better road record (23-11) than a home record (18-15). Also amazingly is how they jumped out of the gate and have stayed in front—with their usual formula of strong pitching (3.55 ERA leads the AL), speed (major league best 76 steals) and defense.

2. New York Yankees (41-26)—Don’t look now, but the Yankees have caught up to Tampa. They just have too much talent for the Rays to keep them down all season.

3. Boston Red Sox (41-28)—Struggling to keep pace with the Rays and Yanks, but now just one game back and right in the thick of it. Does anyone else feel bad for the Orioles and Blue Jays?

4. Atlanta Braves (40-28)—A huge surprise to be leading the NL East on June 19, but not as big a surprise as the Phillies sitting in third place.

5. Minnesota Twins (38-29)—Ignited by a new ball park and a fat new contract for their superstar catcher Joe Mauer, the Twins are going to run away with the AL Central because no one else wants to.

6. San Diego Padres (39-28)—Definitely the surprise of the first two months, Bud Black has this Padres team over-achieving. They recently relinquished first place, but took it right back, and the Padres may stay in the hunt because of how well they fare in those close, low-scoring games.

7. New York Mets (39-28)—Here’s another shocker. The Mets were picked by most pundits to be a fourth or fifth place team. And here they are battling the Braves for NL East supremacy. But the biggest surprise has been the starting rotation, where guys like Mike Pelfrey, RA Dickey and Jon Niese are reminding Mets fans of the Seaver/Koosman/Matlack days. And we haven’t even mentioned Johan Santana.

8. Los Angeles Dodgers (38-29)—They’ve quietly made their move from bottom feeders to frontrunners, and they have the talent to stay there. But seriously, Manny Ramirez has SEVEN home runs on June 19? Hmmmm.

9. Texas Rangers (39-28)—Everyone thought the Mariners would be the team to beat in the AL West this year, but they have one of the worst records in baseball at 26-41. Meanwhile, the Rangers are riding a frightening middle of the lineup (Guerrero/Hamilton/Cruz) to the division lead

10. San Francisco Giants (37-29)—With Barry Zito looking like his old self, this team is extremely dangerous with him, all-world Tim Lincecum, Matt Cain and Jonathan Sanchez.

Tie 10. Detroit Tigers (37-29)--A 7-game winning streak has them right here and only a half-game back of the Twins.

It was a moment that had been hyped up since the start of the season, but due to Mother Nature (that whore), Randy Johnson won his 300th career game in front of a rain soaked crowd of about 10 people.

Nevertheless, he’s now a part of the illustrious 300-win club.

Johnson pitched six innings on Thursday, allowing just two hits and one unearned run in the Giants’ 5-1 victory over the Nationals. He got a fair amount of help from his bullpen, who pitched three scoreless innings in a steady rain to preserve the Giants’ lead, which had been 2-1 until the ninth inning when San Fran scratched across three more insurance runs.

With the win, the Big Unit became only the 24th pitcher to get to 300 victories and is the second-oldest pitcher to achieve the milestone. He’s also the first pitcher to get his 299th and 300th win in consecutive starts since Tom Seaver did it in 1985.

One moment that’ll surely be overlooked from this game is an amazing defensive play by Giants second baseman Emmanuel Burriss in the fifth inning. With the Giants up 2-0, Johnson gave up a hit to Elijah Dukes, who advanced to second on a passed ball the very next batter.

Johnson then walked Austin Kearns, which brought the leading run to the plate in Ronnie Belliard. Belliard then scorched a pitch that ricocheted sharply off the mound and looked to be heading into center field for a base hit. But Burriss made a diving stop and flipped the ball with only his glove to shortstop Edgar Renteria, who got the force out at second and then completed the double play by throwing out Belliard at first. Johnson then got Will Nieves to ground out to Burriss to end the inning and preserve the Giants’ 2-0 lead.

Even though nothing can take the moment away from the Big Unit, it’s a shame that not more people were in attendance to enjoy the victory. That said, his family was front and center and that’s all that matters. It’s a fantastic milestone for Johnson, a player that never cheated the game. (At least as far as we know, that is.)
