Arizona's Dan Haren is only 7-5 this year, but he leads the NL in ERA, WHIP and innings pitched.

By Peter Gammons, ESPN

This week marks the halfway mark of the season, so it's time to pick the halfway Cy Youngs.

And we saw a lot of former Cy Young winners on the mound this week. On Tuesday alone, there were five honorees on the mound across the majors. But those are past winners. What about this year?

Kansas City's Zack Greinke is pretty obvious. He leads the majors in earned run average (1.95); in fact, he's the only one who still has an ERA lower than 2.00. He's tied for the most wins in baseball with 10, and this on a last-place club with bullpen issues. He has had but two non-quality starts.

Even with the way Greinke has dominated so far this season, though, the best pitcher at this point in the year is Arizona's Dan Haren, who beat the Reds on Tuesday by striking out nine and allowing just one run over seven innings. Cy Young winners usually have to run up big numbers, which Haren probably would have done if his team had played better and his bullpen not underachieved. His 7-5 record would be 11-1 with a whole bunch of other teams.

These are the facts: Haren leads the NL in ERA at 2.19; he's second in all of baseball, trailing only Greinke. He is by far the leader in quality starts, with 15 of 16. His 0.81 WHIP is sick, as is his 7.5-1 strikeout-walk ratio. The 0.81 WHIP is the only one in baseball under 1.00; Greinke is next at 1.02. The OPS against him is .533, which means that the average batter against him is doing just a little less than Brian Bixler.

The Diamondbacks have to figure out the best plan to get Brandon Webb healthy, and whether to pick up his option for 2010, and Webb has to figure out the best course for his future. (It was announced Wednesday that Webb would not have shoulder surgery and that he hopes to return in September).

Arizona knows it is out of it for this season, so the D-backs will look to see what they can get for Doug Davis, Felipe Lopez, Jon Rauch, Tony Pena, Chad Qualls and others, and will allow their extraordinary young players such as Justin Upton reboot the franchise.

Meanwhile, they will need to try to score enough to keep Haren in the Cy Young chase.

The complete list of Wednesday's homers

ON DECK: THURSDAY'S BEST MATCHUPS

Phillies at Braves, 7 p.m. ET

The trip to Atlanta hasn't gone all that well for the Phillies. They lost the series opener Tuesday in 10 innings. On Wednesday, they couldn't figure out Braves right-hander Jair Jurrjens, who flirted with a no-hitter and ended up giving up only one hit over seven innings in Atlanta's win. J.A. Happ tries to help the Phillies escape the sweep.

Giants at Cardinals, 7:15 p.m. ET

Barry Zito hasn't been going deep into games -- he has gone more than 5 2/3 innings only once in his past five starts -- but he has been mostly effective, going 3-1 with a no-decision over that stretch.

Orioles at Angels, 10:05 p.m. ET

Although he did not win his last time out, John Lackey did have his best outing since coming off the disabled list. He allowed five hits and one run over seven innings and struck out nine in a no-decision of a 2-1 win against the Diamondbacks.
