MIAMI -- Jeff Mathis' season started and is now ending with a fracture.
The veteran Marlins catcher will miss the remaining three games with a fracture to his right thumb.
Mathis bruised his thumb while blocking a pitch on Sept. 9 against the Braves.
An initial X-ray came back negative, and Mathis returned to the lineup on Sept. 16. He tried to play through, and he appeared in seven more games before feeling more discomfort.
A second X-ray was taken after he came out of the game on Sept. 24, and a fracture was detected.
"His season is over," manager Mike Redmond said.
Mathis missed the first month of the season with a right collarbone fracture.
Mathis appeared in 73 games, and he batted .181, with five home runs and 29 RBIs.
Koyie Hill started at catcher on Friday night against the Tigers, and Rob Brantly is the other healthy catcher on the roster.
Also on Friday, it was announced that rookie outfielder Jake Marisnick will be undergoing a scope on his left knee, so his season is over.
The 22-year-old rookie outfielder opened the season at Double-A Jacksonville, and he was called up in late July. Initially, he started a majority of the time in center field. But he began to slump, and in 40 games and 109 at-bats, he ended up hitting .183 in the big leagues. He batted .280 in the Minors with 12 homers and 46 RBIs.
Cishek a model of consistency as Marlins' closer
MIAMI -- A constant in a rough season for the Marlins has been the steady performance of Steve Cishek.
When given a chance to close out a game, Cishek has repeatedly delivered.
The 27-year-old did it again on Wednesday night, and in the process he established a franchise record.
Cishek tossed a scoreless ninth in Miami's 3-2 win over the Phillies on Wednesday. It was the side-arm-throwing right-hander's 28th consecutive save, which topped the mark of 27 previously set by Todd Jones in 2005.
He extended his record streak to 29 saves after pitching another scoreless ninth inning in Friday's 3-2 victory over the Detroit Tigers.
Cishek last failed to convert a save on June 4 at Philadelphia, when he allowed the tying run at Citizens Bank Park.
Since then, Cishek's 29 saves is tied for the third most in the Majors. Kansas City's Greg Holland has 37 saves in that span, followed by Atlanta's Craig Kimbrel's 33 and Baltimore's Jim Johnson's 29.
"Early on in the year, I was a little bit on and off," Cishek said. "I felt like I was throwing harder. I felt better, actually. Now, I've kind of toned it down a little bit. My [velocity] is where it was last year, 90-92, maybe 93. Being down in the zone is a big thing."
From June 5 to Friday's game against the Tigers, Cishek has a 1.24 ERA in 43 games.
"Even when I felt like garbage out there, I found a way to get three outs, which is something I struggled with last year. I was so up and down," Cishek said.
This is Cishek's first season as a full-time closer. He inherited the role in the second half of 2012 from Heath Bell.
"This has been a big learning experience for me," Cishek said. "It's been a solid individual year. Obviously, I'm more concerned about the team outcome."
Dobbs sees a bright future for Marlins
MIAMI -- The way Greg Dobbs sees it, the overall record doesn't tell the story about the Marlins' future.
Although Miami is going to finish with the second worst record in the Majors and last in the National League, the 35-year-old envisions a bright future. That's why he sought a contract extension for next year, and it was actually reached months ago.
On Thursday, it was confirmed the Marlins have locked up Dobbs for 2014, but no official announcement has been made. The deal is worth $1.7 million, after he earned $1.5 million this season.
Dobbs' representatives came to terms in June with Miami owner Jeffrey Loria.
It was Dobbs' wish to keep the signing private, because the Marlins were off to a rough start, going 14-41 in the first two months.
"It's not like this just came about," the veteran left-handed hitter said. "This started a long time ago. It was a long process. A lot of stuff was going on at the time within the organization. I understood there wasn't a pressing need to get it done.
"I wanted them to know I wanted to be here, I wanted to be a part of turning this organization around."
Dobbs is primarily a pinch-hit specialist. And his 95 career pinch-hits are the most of any player in the Majors since he was a rookie in 2004.
Dobbs didn't want his signing to overshadow the team.
"It was my wish, at the time, to not have it announced," he said. "I didn't want that to get in the way of the focus of everyone here. I wanted the focus on us playing better baseball and trying to get out of the rut that we were in."
Talks about an extension began in the winter, and carried through Spring Training.
"It was mostly my wish that we table it," Dobbs said. "I didn't need a press conference. My focus was more, 'Let's just focus on the team.' I didn't want anything to distract from the team."
• Infielder Ed Lucas became a father on Friday. His wife gave birth to a boy, and Lucas was not with the team for the series opener. Lucas is expected back Saturday.
• Also on Friday, the Marlins named outfielder Brent Keys and right-hander Anthony DeSclafani as their Minor League Player and Pitcher of the Year. The two were recognized during a pregame ceremony.
Keys, 23, won the Florida State League batting title with a .346 average (132-for-381) in 95 games at Class A Jupiter.
DeSclafani, 23, combined for a 9-6 record with a 2.65 ERA (129.0 IP/38 ER) in Class A Jupiter and Double-A Jacksonville.
