Dice-K making progress with elbow inflammation

WASHINGTON -- Slowly, Daisuke Matsuzaka is making his way back from a bout of right elbow inflammation. Matsuzaka has been throwing off flat ground in recent days, and could begin doing so off a mound soon.

"He's got to get on a mound and start spinning it," manager Terry Collins said. "But I wouldn't be surprised if he's out pitching early next week."

Once Matsuzaka resumes mound work, Collins continued, he will likely require a Minor League rehab start -- even if his ultimate destination is a return to the bullpen. On the disabled list since July 26 with what initially seemed like a potentially serious injury, Matsuzaka has served the Mets as a starter, long reliever, setup man and closer this season. He was 3-3 with a 3.87 ERA prior to his injury.

Mets relieved Lagares OK after diving catch

WASHINGTON -- The Mets' worst fears were averted when Juan Lagares recovered just fine from the dangerous catch he made in Tuesday's win over the Nationals.

With a man on third base in the seventh inning Tuesday, Nationals outfielder Denard Span hit a sinking line drive to center, where Lagares sprinted in and dove to catch it. Though Lagares made the catch, he landed awkwardly, prompting fears of a broken wrist when he remained motionless on the field.

Trainers sprinted out, but Lagares simply had the wind knocked out of him. He remained in the game and was in the starting lineup Wednesday against the Nationals.

"He's fine," manager Terry Collins said. "He just took a jolt to the stomach, so he's all right. Great catch."

Worth noting

• Mets principal owner Fred Wilpon joined the team Wednesday on its annual trip to the Walter Reed National Military Medical Center in Bethesda, Md. The Mets make the visit once each year, touring the facilities and meeting with injured veterans.

• The Mets on Wednesday traded Minor League pitcher Hunter Carnevale to the Blue Jays. A former 33rd-round Draft pick, Carnevale was 4-1 with a 5.59 ERA in 23 relief appearances split between Class A Savannah and Class A St. Lucie.

Matt Harvey joined the growing legions of people across the nation taking the "Ice Bucket Challenge" to raise money and awareness for ALS. The Mets posted a video of Harvey dunking himself in an ice bath on their Twitter feed. The challenge was established to benefit Boston College baseball player Pete Frates (a former teammate of Mets utilityman Eric Campbell), who is battling ALS.
