PITTSBURGH -- Pirates outfielder Jose Tabata underwent a series of tests Tuesday after leaving Monday's game when his sore left wrist flared up.
Tabata was diagnosed by Dr. Mark Baratz with a small avulsion fracture on the dorsal side of the fourth metacarpal of his left hand. He will rest and receive treatment for 10 days to allow the bone to heal. Tabata will be re-evaluated at that time. He first experienced pain while swinging the bat in the cage before a game on Aug. 24.
"He had the wrist looked at," Pirates manager Clint Hurdle said. "I'll just tell you this -- we're going to put him down for a volume of days, we haven't decided on an exact number, but we're just going to set him down."
Tabata hit .266 with four home runs and 21 RBIs in 91 games this season. He missed a big chunk of the year with an injured left quad muscle.
Pirates make latest round of callups
PITTSBURGH -- The Pirates recalled left-handers Jeff Locke, Aaron Thompson and Daniel Moskos and third baseman Pedro Alvarez from Triple-A Indianapolis on Tuesday.
The club also selected right-hander Jared Hughes from Indianapolis and recalled right-hander Evan Meek from his rehab assignment and reinstated him from the 60-day disabled list.
To make room on the 40-man roster, the Pirates have transferred left-hander Paul Maholm and right-hander Kevin Correia from the 15-day DL to the 60-day DL.
"I think you can help them with their comfort level, as far as getting them here and getting them ingrained in the Major League routine, getting them in the clubhouse amongst their peers, in the routine of a Major League day," Pirates manager Clint Hurdle said of the September callups.
"Statistics is not an end all with me. Statistics in September, they just don't mean the same as they do in June, July and August for me. The two most challenging months to read statistics is Spring Training, when you see performance levels, and September, when you see performance levels.
"That being said, it's an opportunity to play and it's an opportunity for guys that have only been in the Minor Leagues to play that extra month, to understand there is another month to the season. It's not a 132-game season, it's a 162-game season, and when you're good it's more than that -- it's another month. I think there's a lot of pluses from guys coming up and participating in the month of September."
Locke was surprised by his callup.
"Absolutely. Obviously, you want it and you want the opportunity," Locke said. "Everybody up here has been pretty strong all year and there haven't been a lot of moves in the organization with pitchers, and sure enough it all just kind of happened real quick at the end and everyone started going and I was able to be thrown in there too."
"We want to see Locke," Hurdle said. "We've seen Thompson one time, and we anticipate seeing more of him. We've got to continue to monitor our starters. If Jeff Karstens comes back, how many starts will he be able to make before we unplug him again? I think there's going to be opportunity for Locke and Thompson to pitch up here before the season is over."
Hughes was a bit a of a surprise callup.
"Our Triple-A staff banged the drum extremely hard for Hughes," Hurdle explained. "Just his work throughout the season and volume of work throughout the season, the consistency, the hard sink and late life on the fastball. Some quick innings put away; it's something they've seen a lot of and they've seen this guy continually go out there and sink the ball with plus velocity and good command."
Pirates transfer lefty Maholm to 60-day DL
PITTSBURGH -- The Pirates transferred lefty Paul Maholm from the 15-day disabled list to the 60-day disabled list on Tuesday. Maholm has been ruled out for the rest of the 2011 season due to a left shoulder strain.
"Obviously, for pretty much my first five-plus years I've made almost every start, so I hate missing seven starts at the end of the year," Maholm said. "Not being able to pitch is disappointing, but this is probably my first common-sense move for my career. To just say, 'Let's not push it and let's make sure we're good to go and not take a chance to make one start and try and prove I'm healthy, and then all of a sudden something else pops up.'
"I'm feeling good and feeling healthy now, and I think I can probably start throwing soon. I've got to go see Dr. [James] Andrews and more or less get cleared and start to do my normal training and get back after it."
Maholm could hit free agency this winter if the Pirates decide to decline his $9.75 million club option for 2012.
"It's up to them," Maholm stated. "They've got the option. I've been saying for seven months I'd be open to [staying], and I haven't heard anything. So we're just going to see; no hard feelings if anything happens. If I go test free agency, obviously Pittsburgh will be one of the teams that I hope wants me, and we'll see how it goes."
Pirates recall Alvarez, start him at third base
PITTSBURGH -- The Pirates recalled third baseman Pedro Alvarez from Triple-A Indianapolis on Tuesday. Alvarez has been a disappointment in the Major Leagues this season, where he's hit .196 with three home runs and 15 RBIs in 56 games.
Alvarez batted .154 in August at Indianapolis and .100 in September. He is expected to see a handful of starts at third base down the stretch and was in the lineup on Tuesday against Houston.
"Well, number one, I'm going to give him a start when I think it's a good matchup," Pirates manager Clint Hurdle said. "That's basically tonight's decision, the way that it's fallen. Josh Harrison has played a number of games and it's not going to hurt him to back away for a day. He'll be in there tomorrow and he'll continue to play if he continues to produce. We'll just find some starts for Pedro and hope he has some success, and maybe he can get some traction going that way."
