Washington Nationals’ Enny Romero lifted with tightness in left forearm in Miami...

Enny Romero left an outing against the Arizona Diamondbacks on July 23rd with back spasms, so when he was lifted in the middle of the sixth inning tonight in Miami, the assumption was that his back had acted up again.

Apparently it was a forearm strain, however, according to what Washington’s skipper Dusty Baker told reporters after the Washington Nationals’ 7-0 loss to the Marlins.

“No, he had — in his forearm, he had like a tightness in his forearm,” Baker said, “it spasmed, and same thing as a strain, so we’re going to use precaution on Enny.”

Baker also said that Romero, 26, is likely headed to the DL, with Sammy Solis coming back up after getting optioned to Triple-A Syracuse earlier this afternoon when A.J. Cole was called up and Brandon Kintzler was activated following this past Monday’s trade from the Minnesota Twins.

“Maybe. We’re looking at it, yeah. And we’ve got to call back Sammy.”

In 45 games and 47 ¹⁄₃ innings pitched this season, Romero, who was acquired from the Tampa Bay Rays in February, has put up a 3.99 ERA, a 4.13 FIP, 20 walks (3.80 BB/9), and 57 Ks (10.84 K/9).

Baker just talked earlier today, in an MLB Network Radio interview, about the progress Romero has been making in recent weeks, telling hosts Casey Stern and Brad Lidge the lefty was finally starting to get his secondary pitches over to complement his high-90s heater.

Will this be a significant setback for Romero? Or a minor blip? It’s a blow to the Nats’ relief corps following the recent trades made to shore up the bullpen by bringing in Ryan Madson, Sean Doolittle, and Brandon Kintzler.
