Struggling left-hander Derek Holland joined Yu Darvish on the disabled list Wednesday before the Texas Rangers said yet another starter, Colby Lewis, was headed there as well.

A day after Lewis (6-1, 3.21 ERA) had cramping in his right arm while pitching five innings in a loss to Cincinnati, an MRI on Wednesday revealed he has a lat muscle strain that will keep him from throwing for at least four weeks.

METS: Slugger Yoenis Cespedes should miss no more than a couple of games and pitcher Noah Syndergaard is expected to make his next start.

A day after both players were hurt in a win over Kansas City, the Mets said Thursday that neither injury was significant.

Cespedes, who’s third in the NL with 18 homers, has been bothered by the pain in his left wrist over the last week, but didn’t tell Manager Terry Collins until Wednesday.

Syndergaard, who ranks sixth in the NL in both ERA and strikeouts, was prescribed anti-inflammatory medication for his right elbow. An MRI showed nothing wrong with the structure of his elbow.

NATIONALS: Stephen Strasburg, scratched from his scheduled start Monday because of an upper back strain, threw on flat ground. The Nationals hope he makes his next start on Sunday.

TWINS: Minnesota signed first-round draft pick Alex Kirilloff, 18, a corner outfielder from Pennsylvania they acquired with the 15th overall selection.

PIRATES: Right-hander Ryan Vogelsong threw off the slope of the pitcher’s mound for the first time since a pitch hit him in the left eye and caused facial fractures on May 23.

Rookie catcher Elias Diaz (right elbow surgery) is playing catch at 120 feet and remains on course to be activated in mid-July.

VETERAN INFIELDER Omar Infante cleared waivers and became a free agent. Infante was designated for assignment June 15 by the Royals, who chose to pay him the nearly $14 million left on his contract rather than let him ride the bench as a utility player.
