With the benefit of a big lead, Peavy got away from being as aggressive as he was in the early innings and opted to pitch more to contact with the hopes of inducing some easy outs.
The results weren't pretty, as Peavy allowed four runs, ran up a high pitch count and was gone after 5 1/3 innings, although he still earned the victory in an eventual 11-6 victory over the Diamondbacks.
Peavy learned a lot from that start, which explains why he was so aggressive in each of his seven shutout innings Wednesday against the D-backs when he allowed just two hits with 16 strikeouts, including nine in a row.
"I'm not going to be somebody that I'm not," Peavy said Thursday. "I'm going to try and dominate."
Peavy accomplished as much. He allowed two hits in the first inning and then proceeded to strike out the side in the second, third and fourth innings, coming within one strikeout of tying Tom Seaver's Major League record for 10 consecutive strikeouts.
He left after the seventh inning with a 2-0 lead. The Padres' bullpen allowed three runs in the last two innings -- including Stephen Drew's two-run home run in the ninth inning -- as Arizona prevailed, 3-2.
"I felt good, I don't know how many pitches I could have thrown," said Peavy, who threw a season-high 117 pitches. "I want to be smart about everything and help the team win. At the time, I had no idea I had 16 strikeouts or struck out nine in a row."
Bard back Friday? Starting Friday, Padres catcher Josh Bard would just as soon talk about anything other than his strained left groin which, after 15 days on the disabled list, isn't so strained anymore.
Which is why Bard will likely be activated from the disabled list sometime before Friday's game at PETCO Park against the Dodgers. Manager Bud Black wouldn't confirm the impending roster move, though he said he's "leaning toward highly likely."
Bard took part in his third consecutive extended Spring Training game Thursday morning in Peoria, Ariz. He caught six innings and had two hits, including a double, in five at-bats with Black in attendance.
Bard's groin was tested in several ways and, by the time he got to Chase Field in the late afternoon, he said he felt fine and was ready to rejoin the Padres in a playing capacity.
"I felt like it was a good test," Bard said of Thursday's game. "It was hot out there, but my leg felt good. It's learning to play under control. I'm excited to get back. It was nice to get a couple at-bats and get my timing back."
Bard said that he "made some throws, blocked some balls in the dirt and ran the bases," and that he felt strong.
More on Peavy: Padres pitching coach Darren Balsley has had a front-row seat for both of Peavy's 16-strikeout games -- the one on Wednesday and the one last season against Atlanta.
Not surprisingly, Balsley said Peavy looked every bit as dominant against Arizona as he did last season, with one exception -- his stuff.
"I think the only difference was last night he threw more sliders and fastballs," Balsley said. "Last year against Atlanta, he threw a few more fastballs for strike three. He was throwing both for strikes with electric stuff. It's fun to watch a good pitcher do what he can do."
Of course, Peavy pitched with a lead for most of the time he was in Wednesday.
Last season against the Braves, Peavy was pitching behind almost from the start of the game, as he allowed a two-run home run to Ryan Langerhans in the second inning.
Honor for Coleman: Longtime broadcaster Jerry Coleman was not in the booth for the Arizona series as he was being inducted into the Bay Area Sports Hall of Fame on Thursday.
Fellow inductees included former San Francisco 49ers wide receiver Jerry Rice, former Stanford women's basketball player Jennifer Azzi and former San Francisco Giants first baseman Will Clark.
Coleman has already been enshrined in the Padres Hall of Fame (2001) and the U.S. Marine Corps Hall of Game (2005) and was the 2005 recipient of the Ford C. Frick Award from the National Baseball Hall of Fame.
Streaking Gonzo: With his three-run home run in the first inning Thursday, Adrian Gonzalez set the franchise record for the most RBIs in April with 23.
Gonzalez also tied the club record for most home runs in April (seven). Ryan Klesko and Rondell White (2003) and Ken Caminiti (1999) also shared the record.
And to think that Gonzalez still has another four games left in April.
Pads and ends: Pitcher Shawn Estes and catcher Todd Greene -- two players who were invited to Spring Training but are currently injured -- were at Chase Field, talking with teammates before the game. Greene, who dislocated his right shoulder in the first week of the spring, has been hitting in game situations during extended Spring Training games in Peoria. Estes is recovering from Tommy John elbow ligament replacement surgery that he had on his left elbow last June. "They're both progressing," Black said. "Greene has been playing in games. Estes is throwing, building his arm strength back up." Neither is on the 40-man roster.
On deck: The Padres open a three-game series at 7:05 p.m. PT on Friday at PETCO Park against the Los Angeles Dodgers. Clay Hensley (1-3, 9.45 ERA) will get the start for the Padres. He'll be opposed by Mark Hendrickson (1-0, 1.62 ERA).
