Martinez, competing for the final vacancy in the Rangers’ rotation, allowed five hits and walked one. He struck out four, throwing 54 strikes in 74 pitches, and lowered his earned-run average to 0.84 in three spring appearances. He has allowed one run over 9 2/3 innings.

Martinez went 5-12 with a 4.55 ERA as a rookie last year, making 24 starts and five relief appearances.

Martin homered in the third with Robinson Chirinos aboard. Chirinos was hit by a pitch from Chad Bettis.

Ed Lucas, Nate Schierholtz and Adam Rosales delivered run-producing hits in a four-run eighth.

Bettis, optioned to Triple-A on Sunday, was brought back to face the Rangers. He yielded two runs and three hits in four innings, walking none and striking out four.

Bettis made the 2014 opening-day roster as a reliever but is being converted back to a starter. The Rockies’ rotation remains in flux, so his time in the minors could be brief.

Rangers right-hander Ross Ohlendorf, who had been sidelined with a tender right groin, pitched for the first time since March 15. He struck out two in a spotless seventh but left after one inning with recurring tightness in his groin.
