In his first season with the Marlins, Olivo has a caught-stealing percentage of .426, nabbing 26. Among National League catchers, only Yadier Molina of the Cardinals (.455) has a higher percentage. And Pittsburgh's Ronny Paulino (28) has thrown out more, but his percentage (.373) is slightly lower than Olivo.

"He's the whole package," Marlins bench coach Gary Tuck says of Olivo's ability to gun down runners. "He's as good as anyone in the National League."

Working on drills daily with Tuck, Olivo has always had a strong arm. What he's improved on is receiving techniques and blocking the ball. In throwing to second, he's routinely timed at 1.8 seconds. The big-league average is 1.95 to 2 seconds.

The steady strides Olivo has made behind the plate should gain him consideration for the Gold Glove. In the NL, Olivo's .993 fielding percentage is second only to Molina's .997.

Olivo certainly has done his part to slowing down the oppositions' running game. Tuck points out that players steal on the pitcher more than they do the catcher. If a pitcher has a slow move to the plate, or he doesn't hold runners close, stolen bases are more likely.

"If [pitchers] give Miguel a legitimate chance, his [caught stealing] percentage would be sky high," Tuck said. "The four errors he's made have been on rushed throws."

Trade options: Even though the non-waiver trade deadline passed July 31, the Marlins still are exploring outfield help, specifically center field options. The team has not ruled out pulling the trigger on a deal before the waiver deadline expires on Aug. 31.

MLB.com has learned a couple of center field candidates on the Marlins' radar are Boston Minor League prospect David Murphy, and Willy Taveras, the speedster from the Astros.

In exchange, the Red Sox are looking for relief help, and left-hander Taylor Tankersley's name has surfaced. The Marlins have a number of pitching prospects should the team not want to part with Tankersley, who has been effective in late-inning setup roles.

Murphy, 24, went to Baylor and he was the Red Sox's first pick in 2003. He opened the season with Double-A Portland, playing center field. A left-handed hitter and thrower, Murphy appeared in 42 games and was hitting .273 with three home runs and 25 RBIs, before being called up to Triple-A Pawtucket, where through Aug. 11, he was hitting .277 with seven homers and 38 RBIs. He is playing right field and center field in Triple-A, and has been bothered recently with a sore back.

Taveras is another interesting possibility. One of the fastest players in the game, he can lead off and cover a lot of ground in the outfield. Through Sunday, Taveras was riding a 16-game hitting streak.

A right-handed hitter and fielder, Taveras is in his second full season. He's batting .275 with 19 steals.

Should the Marlins not make a trade this month, the team will explore outfield help after the season.

Double-digit winners: Reaching the 10-win plateau as rookies is a telling accomplishment for Josh Johnson and Ricky Nolasco.

The fact that they did it in their first full seasons is even more impressive. Add to that the fact the Marlins' record is below .500 is something they can be proud of.

For big league starters, collecting 10 wins is something to springboard off for the future. Scott Olsen (9-6) still has an excellent chance to reach double-digits in wins. If he does it, the Marlins would become the first team since the 1952 Brooklyn Dodgers to have three rookie pitchers with 10 or more wins.

To put that number in perspective, consider that Josh Beckett topped the 10-win barrier for the first time in 2005, going 15-8. It took the hard-throwing right-hander four full seasons to be a 10-plus game winner, a fact that he was criticized about until he's now done it in back-to-back years.

Brad Penny went 10-10 in his second full season, in 2001 for Florida. And former Marlins, A.J. Burnett and Ryan Dempster didn't reach 10 wins as rookies.

Burnett went 11-12 in 2001, a year after he made 13 starts and went 3-7. Dempster went 14-10 in 2000, his third full season.

Injury update: The way he's progressing, catcher Matt Treanor may indeed be ready to come off the disabled list when he is eligible on Wednesday.

The Marlins will be at the Dodgers that day.

Treanor went on the DL Aug. 3, retroactive to Aug. 1, with a left shoulder strain. The past few days in Arizona, he has taken part in batting and field drills.

Reliever Logan Kensing, on the DL with a right elbow strain, remains hopeful to begin playing catch before the Marlins return to South Florida after Wednesday's day game in L.A.

Coming up: The Marlins begin the final leg of their three-city, nine-game road trip on Monday night at 10:10 p.m. ET at Dodger Stadium. Dontrelle Willis (7-9, 4.08 ERA) looks to get back on track after a loss at Washington. Derek Lowe (9-8, 4.09 ERA) takes the hill for the Dodgers.
