The D-backs haven't done much in the first two games of a three-game series against the Rockies to stop Colorado shortstop Troy Tulowitzki. But they'll get one more shot at it on Wednesday night at Chase Field.
Josh Collmenter is slated to get the ball for the D-backs, and it'll be Jordan Lyles for the Rockies in a battle of right-handers.
Tulowitzki enters the final game of the series having gone 5-for-6 in the first two games with three walks, two homers, five RBIs and four runs.
Entering Wednesday with a .376 batting average, Tulowitzki had no clue that this kind of red-hot hitting was in store for him.
"No, you never do," he said. "This game is too hard to feel anything coming. You're just battling every day trying to get better. You never feel hot streaks. Every day is a new day."
Lyles, making his sixth start of the season, is 3-0 with a 2.93 ERA and has been a nice surprise for the Rockies, who suffered injuries to starters Jhouyls Chacin, who has been on the 15-day disabled list since the end of Spring Training with a right shoulder strain, and Brett Anderson, on the 60-day with a fractured left index finger.
Collmenter was subbed into Arizona's rotation after a poor start by Randall Delgado. The two switched roles and Delgado is now a long man in the pen.
Collmenter picked up his first win of the season in his last outing this past Friday night when he tossed six scoreless innings against the Phillies, walking none and striking out five in the process.
"It's great to be able to give the team a chance to win," Collmenter said. "It's something as a part of the starting rotation you take pride in, going out there and giving the team a chance to win and then hand the ball to the next guy."
D-backs: Miscues on both sides of ball
The D-backs have not played good defense this year and general manager Kevin Towers thinks it's related to the team's struggles at the plate.
"A lot of those are just guys that are taking their offensive struggles out to the field," Towers said of the miscues. I think as some of our hitters start to pick it up and swing the bat better our defense will improve."
Rockies: Weiss impressed by Morneau
Justin Morneau had shoes to fill at first base when Todd Helton retired at the end of this past season. But so far he's impressed with his .351 batting, six homers, 21 RBIs and with Tuesday night's run-scoring triple to extend a 13-game hitting streak.
"He's done as much as we could have hoped," Weiss said about the free-agent signee who was traded from Minnesota to Pittsburgh late last season. "He's been outstanding in every aspect. He's a great leader. He's a great pro. We felt like there was a lot of production left in Justin, and he's showing that. He's been phenomenal."
