Hamels would have been vying for his 15th win of the season, but instead, Cloyd will make his Major League debut after going 15-1 with a 2.26 ERA at two Minor League levels this season. Cloyd, an 18th-round pick of the Phillies in the 2008 First-Year Player Draft, went 12-1 with a 2.35 ERA in 22 starts for Triple-A Lehigh Valley before being called up.
Meanwhile, the 23-year-old Harvey debuted on July 26 and is having a very impressive first go-round in the big leagues. Harvey (2-3, 2.75 ERA) has made six starts and has 43 strikeouts -- the most by any Mets pitcher over his first six career starts.
He last faced Colorado on Wednesday and struck out nine -- his second-highest total of the season -- and allowed one run on three hits in six innings. After the game, he earned high praise from his manager.
"It's not just his God-given ability -- it's what he's got in here," Mets manager Terry Collins said, pointing to his head. "He asks all the right questions. He pays attention. He's the first guy on the bench before a game starts. He's there throughout the game. He listens. He wants to learn."
Mets: Murphy returns, has immediate impact
Daniel Murphy returned to the lineup Tuesday night after undergoing an MRI on Monday. The results of that MRI, which was taken because of a sore right shoulder, revealed no structural damage.
"It just confirmed what I thought. I didn't think there was anything wrong with me," said Murphy.
Murphy entered the game mired in a 4-for-44 slump. However, he went 3-for-5 against Philadelphia in Tuesday's 9-5 win.
Phillies: Schwimer a no-show at Triple-A
Right-hander Michael Schwimer was optioned to Triple-A Lehigh Valley on Thursday, but he never reported within the required 72-hour window. As of Tuesday afternoon, he still hadn't reported.
Schwimer was unhappy with the organization for being optioned rather than placed on the 15-day disabled list. His dispute is that he has an arm injury and was unfairly sent down to the Minors. It is unknown if he's filed a grievance against the team.
Darin Ruf, the No. 12 prospect in the Phillies' organization, is being considered as a September callup candidate when the rosters expand Saturday. He is hitting .317 with 32 doubles, 36 home runs and 96 RBIs in 132 games at Double-A Reading.
"Ruf is somebody that pops out at you," manager Charlie Manuel said. "He's had an extraordinary year."
David Wright is 16-for-49 (.327) with three doubles, three home runs and nine RBIs vs. Hamels.
