Since beginning the year with losses in each of his first three decisions, D-backs right-hander Trevor Cahill has been nothing short of brilliant. Over his last five outings, the 25-year-old has surrendered just six earned runs over a combined 33 innings, good enough for a 1.64 ERA.
The only problem for Cahill since righting his ship has been walking too many batters. Over that same 33-inning span, Cahill has issued 16 walks.
In fact, his last time out against the Marlins, an outing in which he went eight innings and allowed just one run, Cahill walked four batters.
"I got mad a little bit," D-backs catcher Miguel Montero said after the game. "All I told him was, 'I mean you're winning, 6-0, what are you doing? Just throw strikes. I mean really? Trying to guide and nibble?' I don't know what he was running away from. Throw the ball right there and let them hit the ball, let your freaking defense play for you."
What did Cahill say back to him?
"He was like, 'I'm trying,'" Montero said. "Well, stop trying and do it."
Cahill did not walk another batter the rest of the night after that meeting and he'll try to continue that trend Wednesday afternoon when he takes the mound for the D-backs as his club wraps up a three-game set with the Rockies at Coors Field.
Opposing Cahill for Colorado will be Jorge De La Rosa, who is coming off a disappointing start against the Giants last week. Despite earning the win thanks to his offense, the left-hander gave up five runs on nine hits over just five innings.
"When you throw a game like this and your teammates hit well, it's good -- I hope we're still hitting like this, but pitching better next time," De La Rosa said after the game.
In De La Rosa's previous two outings before facing San Francisco, the 32-year-old was dominant, tossing 13 combined shutout frames against the Cardinals and Yankees.
Rockies: Helton gets night off, ready for Wednesday
To help make Todd Helton available for Wednesday's day game, the Rockies gave the first baseman the day off Tuesday night and inserted Jordan Pacheco into the lineup.
"Tomorrow, with Cahill, a heavy-sinker guy who's tough on right-handed hitters, I got 'Check' in there tonight," said Rockies manager Walt Weiss.
The Rockies usually don't start Helton in day games after night games, but since he's got Tuesday night off, he'll be able to make the start.
Weiss said it helps that Helton needs the down time and doesn't fight it.
"Todd's been great," Weiss said. "He understands that. He understood it coming into the season. He's still getting a lot of playing time, but he knows he needs a day here and there. That's what we try to do. 'Check' is a nice piece to have to insert into the lineup, and you can insert him in a number of different spots."
D-backs: Club planning ahead for twin bill
The D-backs have talked about starting Ian Kennedy and Trevor Cahill in Monday's day-night doubleheader against the Rangers at Chase Field.
"It could change," D-backs manager Kirk Gibson said.
With an off-day Thursday and another one next Tuesday, the team would not need to add a sixth starter to the rotation for the doubleheader. The D-backs can add a 26th player to their roster for the doubleheader and will likely call up someone who can pitch multiple innings out of the bullpen.
The 26th player must be sent back to the Minors following the second game.
• The 97 pitches Patrick Corbin threw in dispatching the Rockies on Monday night were the fewest in a 10-strikeout complete game since the Cardinals' Chris Carpenter accomplished the feat June 14, 2005.
• The D-backs are 5-4 against the Rockies this season so far.
