The NL East-leading New York Mets acquired outfielder Darin Ruf from the San Francisco Giants on Tuesday in exchange for infielder J.D. Davis and three pitching prospects, sources told ESPN, confirming multiple reports.

The right-handed hitting Ruf, 36, is hitting .216 with 11 home runs and 38 RBIs this season. He has an .886 OPS against lefties, giving the Mets a player to platoon at designated hitter with left-hand hitting Daniel Vogelbach, who will start against right-handers. The Mets acquired Vogelbach last month in a trade with the Pittsburgh Pirates.

Davis, 29, struggled this season when called upon to fill the DH spot and is hitting .238 with four home runs and 21 RBIs this season.

The Giants also will receive left-hander Nick Zwack, right-hander Carson Seymour and Thomas Szapucki, sources said.

Zwack, 24, is 6-2 with 2.36 ERA in 18 appearances (15 starts) in two Class A stops in the Mets' system, while Seymour, 23, is 5-5 with a 2.76 ERA in 18 appearances (13 stops) in two Class A stops.

The 26-year-old Szapucki, currently at Triple-A Syracuse, made one major league start this season, allowing four home runs and nine earned runs in 1 1/3 innings in a start against the Giants. He is 2-6 with a 3.38 ERA in 18 appearances (16 starts) for Syracuse.
