Any pitcher will tell you that their worst nightmare is any sort of injury to their arm or shoulder area.

Unfortunately for the Texas Rangers, that nightmare appeared to become a reality on Tuesday night in West Sacramento, Calif.

In the seventh inning, the Rangers turned to Luis Curvelo to try to keep their deficit at just one run.

After the first pitch of the outing, Curvelo felt something in his arm, but wanted to continue to pitch and see if it was just a minor thing he could play through.

Curvelo’s very next pitch ended up in the left-handed batter's box with Athletics righty shortstop Jacob Wilson at the plate.

Visibly emotional, Curvelo took off his glove, letting it fall to the ground, and instantly waved out the Rangers trainers.

From that point, Curvelo would not throw another pitch, leaving the game with what the Rangers called a biceps injury.

“You never wanna see that from any player,” Rangers manager Skip Schumaker said after the game.

“We went out there, he was pretty emotional and never felt something like that before he said, but he came back in here, and he feels OK, so we’re trying to figure out exactly what happened and if it’s a biceps thing or a nerve thing or a cramp, we really don’t know yet but we’ll see how he feels tomorrow” Schumaker finished.

After being called up from Triple-A Round Rock just 10 days ago, Curvelo has posted a 5.40 ERA, allowing six hits and three earned runs in three appearances.

Depending on the results the Rangers get with Curvelo at some point on Wednesday, the bullpen could thin out even more.

So far this season, the rebuilt Rangers bullpen has put forth some solid performances, but in the midst of a nine-games-in-nine-day stretch, it is running on fumes a little bit.

The Rangers won’t have an off-day until Monday to be able to get a brief reset for their bullpen before playing another nine-game-in-nine-day stretch, this time at Globe Life Field.

Chris Martin, who also pitched in the game on Tuesday night, told the Rangers of some arm soreness that he had upon his exit.

All of a sudden, Tuesday has become a big day for the Rangers and their bullpen, or potential lack thereof.

With some bad news, the Rangers very well could be tapping into their minor-league system for coverage, at the very least, to get them through this road trip.
