Dodgers roster: Don Mattingly really likes Kevin Gregg

Dodgers manager Don Mattingly was mum on any possible roster moves on Saturday before the Cactus League finale against the Angels in Anaheim, but the Dodgers will likely have a flurry of transactions after the game.

The Dodgers currently have 36 players in big league camp, and the opening day 25-man rosters are due by noon PT on Sunday.

The Dodgers are basically down to three, possibly four open spots. One will be a position player, and is expected to be Justin Sellers, who could not only make the roster but also be the starting shortstop.

Whether there are two or three open pitching spots depends on whether or not the Dodgers place Chad Billingsley on the disabled list to open the season. Billingsley pitched a minor league game on Friday, and would be on track to start a simulated game on Apr. 3 (minor league schedules don't start until Apr. 4), a minor league game on Apr. 8, then slip right into the Dodgers' rotation on Apr. 13, the first day they need a fifth starter this season.

Chris Capuano, who will pitch in relief of Zack Greinke on Saturday night, will occupy one bullpen spot, and Aaron Harang is likely to occupy another. Mattingly said Harang, who started on Tuesday, will next throw a bullpen session.

"We have to figure out how to use (Harang) properly," Mattingly said. "Our job is to put him in the best situation to have success, so this will be a bit of a learning curve, since we haven't seen him (in the bullpen)."

Putting Billingsley on the DL would temporarily give the Dodgers an eight-man bullpen. That spot would likely go to Kevin Gregg, who has allowed one run in 11 innings this spring, with no walks and five strikeouts. The lack of walks are remarkable, as Gregg has averaged 5.21 walks per nine innings over the last three seasons.

"From top to bottom, we like Kevin Gregg. We're trying to make that situation work out," Mattingly said. "He's been great. I know this guy can't be this good, but every time out he just gets outs. He doesn't walk anybody and he throws strikes."

To make room for the non-roster invitee Gregg, the Dodgers could place Scott Elbert on the 60-day disabled list.
