HOUSTON -- With catcher Rod Barajas rejoining the club, the Mets sent outfielder Fernando Martinez back to Triple-A Buffalo.
Martinez was just recalled on Aug. 7 and said he understood the move.
"They had to make a move," Martinez said. "I know I'll be back soon in like two weeks."
Martinez's playing time was limited behind outfielders Carlos Beltran, Angel Pagan and Jeff Francoeur. Manager Jerry Manuel said Martinez needs to work on a few things with his swing.
"The approach that he had is one that doesn't really recognize offspeed pitches," Manuel said. "If you don't recognize offspeed pitches, then you have to guess with that. He's done a good job to survive with what he's doing in guessing what is what."
Barajas returns after successful rehab
HOUSTON -- Catcher Rod Barajas returned to the Mets on Thursday after he completed his rehab stint with Class A St. Lucie. Barajas hit .238 with a homer and five RBIs in five games.
"I'm feeling great," Barajas said. "I went down there and did what I needed to do to get healthy. I didn't feel any discomfort. No setbacks and I feel like I'm ready to go."
Barajas had been out since July 25 with a mild oblique strain. He said he's followed the Mets closely while he's been out.
"This is where you want to be," Barajas said. "I wanted to do whatever I possibly could do. I was ready a few days ago, but I wanted to err on the safe side."
Barajas was in the lineup Thursday against the Astros. He said he's not worried that the Mets will keep three catchers on the roster.
"I don't think it's a big issue," Barajas said. "I think everyone will get their chance to play."
Parnell turns up heat to set season record
HOUSTON -- In his fifth pitch against third baseman Chris Johnson on Wednesday, reliever Bobby Parnell threw a pitch that was officially clocked at 102.5 mph by pitch FX. The pitch was the fastest recorded in the Major Leagues this season.
"I'm excited about it," Parnell said after Wednesday's game. "But today's today and tomorrow's tomorrow."
Parnell pitched two perfect innings for the Mets in their 3-2 win and has now thrown four consecutive scoreless innings. This season he's thrown 13 pitches over 100 mph, which is fourth in the Majors.
"I know I'm throwing good, and I feel like I can let loose," Parnell said "You just try to ride the wave."
Manager Jerry Manuel said he liked what he saw from Parnell and said he could use him as a closer in future games.
"You have to see it on a consistent basis," Manuel said.
Center fielder Carlos Beltran had a scheduled day off Thursday against the Astros. ... David Wright hit his 30th double Wednesday and now has six consecutive seasons of 30 or more doubles, the longest stretch in team history. ... Jose Reyes hit his eighth triple Wednesday to tie for the Major League lead.
