If the Padres can get a single hit off Tim Lincecum on Sunday, it will be an improvement.
Lincecum no-hit the Padres on June 25 and pitched exceptionally his last time out, but Sunday, the Padres will come back with their own pitcher on a hot streak.
Padres rookie Jesse Hahn, 24, is 4-1 in his first five Major League outings, and his ERA is a miniscule 1.95.
Hahn made one start June 3, but struggled through 3 2/3 innings before being sent back down to Double-A San Antonio. The Padres recalled him so he could start June 14, and since then he's made a strong case that he's in the Majors to stay.
Using a mid-90s fastball and a 12-6 curveball, Hahn has gone 4-0 with a 0.75 ERA since being recalled.
"I'm watching this kid develop, and I'm liking what I'm seeing," manager Bud Black said. "We've been impressed by his work here, obviously, so far."
Lincecum, a former phenom in his own right, has recovered from a shaky first two months of the season, lowering his ERA from 5.01 on June 3 to 4.06 after his last start -- an eight-inning scoreless outing against the Cardinals.
Hahn's last outing was the shortest of his recent stint -- he pitched only five innings -- but he set a career high with nine strikeouts.
"Curveball ... was big. I'd say the inside fastball [was key]," Hahn said after the game. "I didn't really have command of my glove-side fastball, so I had to resort to the two-seamer. I don't really care who's in the box, I just go out there and pitch my game."
Giants: Morse breaks homerless drought
It took a month, but Michael Morse finally hit his 14th home run of the season -- and it couldn't have come at a better time.
Morse hit a game-tying solo home run in the ninth inning off Padres closer Huston Street, which allowed the Giants to come back in 10 innings and win, 5-3, on Saturday.
Morse hadn't hit a home run in his previous 24 games, and it didn't look like he was going to come out of his slump any time soon. In his previous 13 games, he had hit only .171 (7-for-41) with three doubles and no RBIs.
Padres: Erlin, Gyorko set for Peoria stint
The Padres announced that second baseman Jedd Gyorko and pitcher Robbie Erlin will take the next step in their injury rehabilitations next week and work out with the club's rookie league team in Peoria, Ariz.
Black confirmed that both players will report to Peoria on Monday and "get back in baseball shape," before they start their rehab assignments.
Gyorko has been out since June 6 with plantar fasciitis in his left foot, but he resumed hitting in the cage Saturday for the first time since his injury, working on soft toss and hitting off a tee.
"He'll be under the guidance of our coaches [in Peoria], taking some grounders and batting practice," Black said.
Erlin has been on the disabled list since May 22 with elbow soreness and was scheduled to throw a bullpen Sunday in San Diego before going to Peoria.
There still is no set timeline for either player's return, but both will likely be out until after the All-Star break.
"We'll get them through this week and then reconvene about what they're doing," Black said.
• Street's blown save Saturday was his first since Sept. 29, 2013, which also came against the Giants.
