Benefitting from a pitch-timer infraction, the Arizona Diamondbacks scratched across a run in the last of the ninth inning on a two-out, two-strike single by Corbin Carroll to beat the Colorado Rockies 2-1 for a fifth consecutive win on Thursday in Phoenix.

After the Rockies tied the game in the eighth with their lone run of the night, Juan Mejia (0-4) got ahead of Gabriel Moreno 0-1 leading off the last of the ninth before committing a pitchers' delay of game, resulting in a ball.

The at-bat wound up going eight pitches, with Moreno drawing a walk.

After a sacrifice bunt by pinch hitter Jose Fernandez and a strikeout, Ketel Marte got a free pass from Mejia before Carroll took the count to 2-2 and then lashed a single to right field for Arizona's second walk-off win in the past three days.

Paul Seward (1-4), who pitched a scoreless top of the ninth, was credited with the win.

Down 1-0 into the eighth, the Rockies forged a late tie when a Juan Morillo pitch hit Tyler Freeman with one out and the bases loaded. Troy Johnston, who had singled three batters earlier, scored the run.

Kevin Ginkel came on with the score tied and the bases loaded and escaped further damage by getting Hunter Goodman to foul out and Ezequiel Tovar to ground out.

After starters Zach Agnos of the Rockies and Eduardo Rodriguez of the Diamondbacks took a scoreless game into the last of the sixth, Arizona scored its first run of the game against Colorado reliever Blas Castano. Ryan Waldschmidt walked, took third on a Marte single and scored on Carroll's infield out.

Scheduled to serve as an opener, Agnos wound up going five full innings in his first big-league start. He allowed just one hit -- a single by Marte in the third inning -- while walking one and striking out four.

Neither he nor Rodriguez, who worked seven innings and left with a 1-0 lead, got a decision.

The Arizona left-hander served up four hits and walked one, striking out four.

Marte had a pair of singles for the Diamondbacks, who got only four hits, all singles.

Tovar had the game's only extra-base hit, a double, for the Rockies, who dropped their third in a row. Agnos threw five shutout innings, permitting one hit and one walk while fanning four.
