NEW YORK (AP) — Mets ace Matt Harvey has thrown off the mound for the first time since having right elbow reconstruction surgery in October.

Mets manager Terry Collins said Friday the All-Star right-hander threw at about 60 percent. General manager Sandy Alderson said the mound session lasted 15 pitches.

Harvey said it was exciting to get back on the mound for the first time since Oct. 22 Tommy John surgery.

Alderson said this was an abbreviated session as part of Harvey’s rehab plan. The program will begin in earnest on Tuesday at the Mets’ complex in Port St. Lucie, Florida, and run through the beginning of October. It will include facing batters in the instructional league.

3 aces go on DL

Cliff Lee

WASHINGTON (AP) — The Philadelphia Phillies placed left-hander Cliff Lee on the 15-day disabled list with an elbow strain Friday and recalled left-hander Cesar Jimenez from Triple-A Lehigh Valley.

Lee left in the third inning of Thursday night’s win over the Washington Nationals with a left flexor pronator strain, an apparent recurrence of the injury that put him on the disabled list in May.

Manager Ryne Sandberg said Friday that Lee will be examined by the team doctor Saturday in Washington, and undergo an MRI and additional tests when the team returns to Philadelphia early next week.

The 35-year-old Lee (4-5, 3.65) missed two months because of a strained left elbow, and was making his third start since coming off the disabled list.

Jimenez, 29, appeared in two games for Philadelphia in June, pitching two scoreless innings. With Lehigh Valley, he was 3-2 with a 1.45 ERA in 38 games, including two starts.

Tyler Skaggs

ST. PETERSBURG, Fla. (AP) — The Los Angeles Angels placed left-hander Tyler Skaggs on the 15-day disabled list Friday because of a strained forearm and recalled left-hander Michael Roth from Double-A Arkansas.

Skaggs was hurt Thursday night in a 1-0, 13-inning win at Baltimore. The left-hander had not allowed a hit when he left with two outs in the fifth.

Angels manager Mike Scioscia hopes Skaggs will pitch again this season, but says the injury “might take a little bit of time” to heal

Skaggs is 5-5 with 4.30 ERA in 18 starts this season.

Roth is making his second stint with the Angels this season. In his lone appearance this year, he went two perfect innings to get a win against Houston on July 5.

Henderson Alvarez

MIAMI (AP) — Miami Marlins All-Star pitcher Henderson Alvarez was placed on the 15-day disabled list Friday because of inflammation in his right shoulder.

The move was retroactive to Wednesday.

The Marlins also recalled left-hander Dan Jennings from Triple-A New Orleans.

Alvarez, who was scheduled to start Sunday game against Cincinnati, was named to the All-Star team this season for the first time in his career. He’s 8-5 with three shutouts and a 2.48 ERA.

Alvarez pitched seven scoreless innings Tuesday in a 3-0 victory over Washington. He showed some discomfort in the second inning, but stayed in the game after manager Mike Redmond and trainers tended to him.

The Marlins acquired right-handed starting pitcher Jarred Cosart from the Houston Astros shortly before Thursday’s non-waiver trade deadline and Cosart will make his team debut Friday against Cincinnati.

Jacob Turner, who was briefly moved to the bullpen in place of Cosart, will start Sunday in Alvarez’s spot.
