Rangers pitcher Nick Martinez struggled in his spot start Tuesday, giving up four runs (two earned) on six hits and three walks in five innings while striking out one but not factoring into the decision in his team's 5-4 win over the A's.

Martinez threw just 50 of his 92 pitches for strikes in the game, which was his second start of the season. He should return to Triple-A with Matt Harrison on his way back, presumably this weekend. Martinez owns a 4.09 ERA and 4:6 K:BB ratio in 11 innings with the Rangers.
