Ike Davis is looking forward to playing more regularly with the Pirates, something he did not get to do with the New York Mets before being traded last week.
"Getting the chance to play every day, you have chances to have good days," said Davis, who had 24 at-bats for the Mets.
"That's the key, getting out there every day and getting at-bats. You play once every four days, if you don't have a good day that day, it can go on and on. I've actually felt good all year, even when I was with the Mets."
He endeared himself to Pittsburgh with one big swing Monday night -- a grand slam in the fourth inning that put the Pirates ahead, 4-2.
"I didn't know if it was getting out. He kind of jammed me a little bit," Davis said of Reds pitcher Mike Leake. "I happened to hit it well enough to sneak over the fence. I knew at least I was going to get a sac fly, which was a good feeling."
Pirates manager Clint Hurdle said landing Davis took patience by general manager Neal Huntington.
"We had interest in Ike over the winter, and one of the things that Neal does very, very well, is he hunts. He hunts for a fair deal. He stays after it," said Hurdle.
"In our industry, it takes courage to have patience because of external noise ... to stay on it, stay with it and get this deal done at this time of the season it's real good for us."
Rodriguez has knee drained
Wandy Rodriguez will take a couple of days to recover from having his knee drained Monday before throwing a bullpen session, said Hurdle.
The club did not share results of an MRI that Rodriguez had.
"We're going to give that a couple days to settle down, then he'll throw a bullpen, and we'll move forward as he's capable of moving forward," said Hurdle.
Hurdle had his knee drained last month and said it never has felt better. He also said it's too early to tell how serious the problem is that put Rodriguez on the 15-day disabled list Monday.
"It's unclear. It depends on the guy. It depends on the age, what's involved. We'll just have to wait and see," said Hurdle.
"I think a knee can be different. You can get your knee drained and never have to get it drained again. You can get your knee drained and have it drained again in two months. I know a couple of people who got their knee drained and surgery in the winter. I actually got mine drained the last week of spring training, it's never felt better, it's never worked better."
Mercer back in lineup
Shortstop Jordy Mercer returned to the lineup Tuesday after getting spiked in the ankle over the weekend.
He said nothing was structurally damaged and that the injury could have been a lot worse.
"Just bruised. ... But it was really tender and sore the last couple of days," said Mercer. "It's good. Pretty much everything is back to normal."
He said the swelling is down and that he's lucky the bone wasn't damaged.
