"I had a good week of work, felt OK in the pen. I was just missing balls over the plate, and they hit them pretty well," said Haren, the Diamondbacks' opening day starter. "I got my pitches in. I'll go out next time and be fine."
Haren was scheduled to throw about 90 pitches in six innings. But he threw about 80 in four innings and gave up five runs in the second. His spring ERA is 5.60.
Haren faced two Cubs regulars -- shortstop Ryan Theriot and second baseman Mike Fontenot. Left-handed batters Jim Adduci and Tyler Colvin doubled off Haren, and Fontenot hit a triple off the right-hander.
"They had a lot of lefties out there," Haren said. "Most (of them) I haven't heard of. Those guys, they're trying to make the ballclub."
"They're obviously very aggressive. I knew that coming in," Haren added. "I made some good pitches they hit and some others were out over the plate."
Haren said he'll focus on putting together a good week of work and potentially throw 100 pitches in his next spring outing. He struggled after rough outings this week by starters Edwin Jackson (8.25 ERA) and Billy Buckner (11.66 ERA).
"Coming down the end of spring, the adrenaline level, it's hard to get pumped up for this stuff," he said. "You go out opening day, I'm sure there will be 40,000 people there. It'll feel a little different from 5,000 people under the sun in Tucson. I'll be just fine."
Left-hander Tom Gorzelanny allowed two runs and five hits in six innings for the Cubs. His ERA is 3.07. Gorzelanny is competing for a spot in the starting rotation, which will be announced Friday. He struck out four and walked one.
"I was in the zone a lot," Gorzelanny said. "I wasn't trying to overthrow. I wasn't trying to do too much. I was trying to throw strikes. I felt like I made some major strides today." He struck out four, walked one and allowed a leadoff home run to Conor Jackson (his third of the spring) and doubles to Jackson and Mark Reynolds. Arizona played most of its starting lineup. Gorzelanny is competing for one of two rotation spots with Sean Marshall, Carlos Silva and Jeff Samardzija.
"If I'll get to be in the rotation, I'm going to run with it and try to claim that spot and keep it," Gorzelanny said. "That's my objective right now."
Cubs manager Lou Piniella has a sore back and didn't make the trip to Tucson. Bench coach Alan Trammell was the interim manager.
Diamondbacks right fielder Justin Upton was out of the lineup after spraining his left ankle Wednesday. Manager A.J. Hinch said if it were the regular season, Upton could have played. He is day to day, but said he hopes to be in the lineup Friday, when Arizona plays the Chicago White Sox. Upton hit and took infield Thursday. Hinch said, "it's hard to say" if it's realistic for starting pitcher Brandon Webb to be ready by late April. Webb has yet to face hitters this spring and is expected to begin the season on the disabled list.
