Mets reliever Carlos Torres is considered the likely candidate to start Saturday against the Brewers if Shaun Marcum is unable, according to the New York Post. The Mets are considering putting Marcum on the disabled list.

Marcum would not reveal what injury would force him to the disabled list, but a source told the Post the veteran right-hander underwent an MRI on his upper back Tuesday.

Manager Terry Collins said Sunday Torres would likely be the next guy up if the Mets needed a starter. Torres started in the minors before joining the Mets' bullpen. He was 6-3 with a 3.89 ERA in 12 starts for Triple-A Las Vegas.
