MARINERS 5, ROCKIES 4 (AT PEORIA STADIUM)
Guerrero’s blast came in the seventh inning against veteran Colorado reliever LaTroy Hawkins. It struck high off the 40-foot batter’s eye beyond the center-field wall.
It provided the Mariners with a 5-3 lead.
Guerrero is the nephew of former All-Star Vladimir Guerrero and ranked No. 4 on the TNT’s Top 10 list of prospects.
Mariners starter J.A. Happ pitched four scoreless innings while allowing two hits and two walks. He struck out four.
“I felt better,” he said. “I felt my direction to home was better. I had a little more life to my fastball, maybe. I feel good about it.”
Happ was hit in the right arm by Corey Dickerson’s leadoff drive in the third inning. After a brief check, Happ remained in the game and finished with 69 pitches, including 44 for strikes.
“I haven’t seen a replay,” he said, “but it’s fine. Not (an issue) at all.”
Second baseman Robinson Cano made slick pick-ups and flips to Miller that started double plays in the first two innings.
Seth Smith hustled his way to a double in the first inning on a grounder up the middle.
