Rangers starting pitcher Martin Perez was hit hard Monday in his start against the Diamondbacks. 

Perez allowed nine hits in 5 1/3 innings, though just two of them went for extra bases. He allowed four runs -- three earned -- while walking two batters and striking out two more. Perez threw just 52 of 96 pitches for strikes.

Perez, who posted a 5.45 ERA in 12 appearances last season, is likely heading back to Triple-A Round Rock, as he was just called up for the start as the 26th-man for the team's doubleheader.
