Ten Dodgers become free agents.

The Dodgers declined to exercise the 2013 club options on Todd Coffey, Juan Rivera and Matt Treanor.

They join another seven players who became free agents today: Brandon League, Shane Victorino, Randy Choate, Jamey Wright, Joe Blanton, Adam Kennedy and Bobby Abreu.

In other words, no big names or surprises for the Dodgers on the first day of free agency. Players can only sign with new teams beginning at 9 p.m. Friday. Between now and then, the Dodgers can re-sign any of their in-house free agents, and they’ve already opened discussions with League’s representatives.

General manager Ned Colletti said that he would like to bring back Choate and Wright, as well, to keep intact a bullpen that finished the 2012 season strong.

Coffey, Rivera and Treanor now fall into the category of Victorino, Kennedy and Abreu: highly unlikely to be on the roster next season.

Blanton is an interesting case. The Dodgers gave him what amounted to a 10-start audition in August and September. In five starts at home, the 31-year-old right-hander went 1-1 with a 3.60 ERA. Not bad. In five road starts he was 1-3, 6.51. Bad.

I guess that makes Blanton a “known quantity” for a team that is looking to add a starting pitcher. But looking at a free-agent market that now includes Zack Greinke, Anibal Sanchez, Ryan Dempster, Kyle Lohse  and Hiroki Kuroda (another “known quantity”), the Dodgers probably figure they can do better.

The hot stove is just warming up.

Postgame: Diamondbacks 4, Dodgers 3 (10 innings)

The Diamondbacks beat the Dodgers 4-3 tonight in 10 innings. For a full recap and boxscore click here.

THE BARE ESSENTIALS:

The big story for the Dodgers tonight was what happened to starter Hiroki Kuroda. In the bottom of the sixth inning, Arizona pinch-hitter Rusty Ryal lined a 2-2 pitch right back at Kuroda’s right temple, and the 34-year-old righthander went down immediately. He did move, however, and CAT scans taken after the game at St. Joseph’s Hospital were negative.

Meanwhile, the Dodgers held a 3-1 lead into the ninth but closer Jonathan Broxton allowed back-to-back homers — only his third and fourth homers allowed of the season — to blow the save.

The Blue couldn’t put anything together offensively in the tenth, and the D’Backs came back with a perfectly executed bottom half of the inning off of Ramon Troncoso to get the win. Augie Ojeda singled, Dan Haren bunted him to second, and after two walks, Gerardo Parra hit a walk-off single.

ETC…ETC

The Dodgers took a 3-0 lead, but Ryal’s hit — ruled a ground-rule double — sparked the first run for the D’Backs. From there, the L.A. offense wasn’t the same, with only two hits.

Hong-Chih Kuo and George Sherrill both feasted on an Arizona lineup that was incredibly left-handed in scoreless seventh and eighth innings. The 1-7 hitters in the D’Backs order were lefties.

Offensively, Brad Ausmus had an RBI single in the second, Doug Davis threw a pick-off away in the fifth to score Rafael Furcal, and Mark Loretta hit a sac fly to bring in Casey Blake in the sixth inning.

Matt Kemp didn’t have a hit but still wreaked havoc on the basepaths, reaching base via walk in the tenth inning and stealing second and third.

ON DECK:

Randy Wolf (6-6, 3.43) tries to salvage a game for the Dodgers against Arizona’s Yusmeiro Petit (2-6, 5.87) tomorrow at 1 p.m.
