Mark Teixeira’s barking right hamstring won’t undergo tests until Monday, but the Yankees put the switch-hitting first baseman on the 15-day disabled list Saturday.

“Unfortunately, it’s very frustrating. Hopefully it’s only 15 days and I am back soon,’’ said Teixeira, who left Friday night’s 7-3 win over the Blue Jays in the second inning with what originally was described as a strained hamstring.

However, it turned out to be more than that.

“It wasn’t a blowout, that I am on crutches the next three or four days blowout,’’ said Teixeira who did that in 2010 during the postseason and needed four weeks to recover. “It was a grab, a pull and it’s really tight. Hopefully it gets better over the next couple of weeks.’’

Manager Joe Girardi shifted Kelly Johnson from third to first base Friday night when Teixeira exited. Saturday, Johnson started at first base and could man that spot for the foreseeable future, because there is nobody in the system ready to play in the big leagues and teams traditionally don’t make deals in the first week of the season.

Before Friday night Johnson had appeared in four big league games at first.

Because Girardi used catcher Brian McCann as the DH on Saturday against knuckleballer R.A. Dickey, the Yankees elevated catcher Austin Romine from Triple-A Scranton/Wilkes-Barre, but his stay could be short.

“I could use him as a backup catcher and I could start him if I wanted to,’’ Girardi said of Romine, who backed up Chris Stewart in the big leagues last year, batting. 207 in 60 games, but was felled by a concussion late in the year.
