Rockies place Antonio Senzatela on injured reserve

The Rockies placed the starter Antonio Senzatela on the 15-day disabled list with a lower back sprain. Colorado also selected the receiver Brian Serven to the big league list, optional Dom Nunez at Triple-A Albuquerque and recalled reliever justin laurent.

Senzatela left yesterday’s game against the Giants after two innings. The right-hander came out for the start of the third but left the game during his pre-inning warm-up in discomfort. The injury will obviously cost her time, but the Colorado Springs Gazette’s Danielle Allenck tweet the organization hopes he can return when he is first eligible in two weeks. The Rox are out on Thursday, so they can continue with the other four German Marquez, Kyle Freeland, Chad Kuhl and Austin Gomber on regular rest until next Tuesday.

In his first seven starts of the year, Senzatela boasts a 4.55 ERA. He struck out just 11 of the 137 batters he faced (a league low of 8 percent). It’s a worrying mark even for Senzatela, who typically has one of the lowest strikeout numbers in the game. Nonetheless, his mix of strong control and ground balls translated into decent enough production from behind the spin. Colorado was clearly pleased with his efforts, rewarding him with a five-year extension last September.

Serven, meanwhile, will enter the roster as a replacement for Elias Diaz. This role was given to Nuñez to start the year, but he struggled with limited playing time. Meanwhile, Serven, 27, was off to a scorching 0.273/0.406/0.506 start with the Isotopes. He hit five home runs and fired 16 free passes while striking just 15 times.

A former 5th round pick from Arizona State, Serven is now in line for his first MLB action. The right-handed hitter boasts a more modest .245/.318/.429 slant line over games over six pro seasons, but his blistering start earned him a spot on the depth chart. Colorado had previously only carried Díaz and Nuñez as receivers on the 40-man roster.
