Streaking and Slumping Pitchers
Streaking
Pedro Martinez (3-0, 3.52 ERA), Philadelphia Phillies
The Phillies expected a lift when they signed the veteran righthander, but no one in the organization could have imagined a spotless record after five starts.
Philadelphia has won all five games started by Martinez, who has had two abbreviated outings but appears to be getting stronger. He allowed one run and five hits with nine strikeouts in seven innings in his last start, outdueling Tim Lincecum.
"You can see that he knows what he's doing and he's not just winging it up there hoping that he's getting outs," Lincecum told the Phillies' web site. "He's pitching with a purpose. He knows how to get guys out."
Martinez has 23 strikeouts and just three walks in 23 innings.
Brian Duensing (2-1, 3.81), Minnesota Twins
The Twins might have a better chance of catching the Detroit Tigers in the AL Central if they had showed more patience with their rookie lefthander as a starter, which has been his role since entering the organization in 2005.
Called up for good in early July, Duensing did mop-up relief work before being given a start July 29. He allowed two homers in five innings and was sent back to the pen, where he again was ineffective.
In 30 1-3 innings as a reliever, Duensing had 20 strikeouts, 16 walks and three homers allowed.
Duensing got another start Aug. 22 and has stayed in the rotation. In three starts, he is 2-0 with a 1.42 ERA. In 19 innings, he has 18 strikeouts, four walks and no homers allowed.
Returning
Bruce Chen (1-6, 5.24), Kansas City Royals
The veteran lefthander won his first game in nearly four years on Aug. 6, then was bumped from the rotation when Gil Meche returned from back spasms.
Chen has made five relief appearances since, allowing at least a run in each but stretching out to work four innings with 70 pitches on Sept. 2.
After pitching just 10 total innings in 2007 and 2008 due to arm problems, Chen is 1-6 with a 5.40 ERA as a starter this season, allowing opposing hitters to hit .304.
Slumping
Rick VandenHurk (2-2, 4.91), Florida Marlins
The 6-5 righthander has alternated good and bad starts in his last four outings and is due for a bad one.
On Aug. 5 at Washington, he gave up three homers and five earned runs in four innings. On Aug. 16 vs. Colorado, he surrendered three homers and six earned runs.
since returning in late July from elbow surgery, VandenHurk has been ripped for nine homers in just 36 2-3 innings.
Billy Buckner (2-6, 8.29), Arizona Diamondbacks
The righthander's last start marked his return from a mid-season demotion, but he picked up where he left off, losing his fifth straight outing.
During that stretch, Buckner has an 11.09 ERA, a 2.01 WHIP and has given up seven homers in 24 1-3 innings, including at least one in each start.
