Diamondbacks-Rockies Preview

The Arizona Diamondbacks haven’t been over .500 since defeating

the Colorado Rockies on opening day. They are finally in position

to move above the mark again, thanks to their longest winning

streak in three years.

Seeking a seventh consecutive victory, the visiting Diamondbacks

take on the slumping Rockies as the teams open a four-game set with

a double-header Tuesday.

Since losing a season-worst five straight from May 8-13, Arizona

(23-23) has taken eight of nine. The Diamondbacks have won six in a

row for the first time since an eight-game run April 4-12, 2008,

batting .307 and compiling a 2.89 ERA during the streak.

“We’re rolling on a lot of cylinders right now,” right-hander

Daniel Hudson said after beating Minnesota 3-2 on Sunday. “It feels

good. Everything’s kind of going good right now – our hitting,

pitching, fielding. So I think we’re taking a streak on the road in

a good spot.”

Arizona is four games behind division-leading San Francisco and

a half-game behind second-place Colorado (23-22), which is on the

verge of matching its longest losing streak of the year after a

three-game sweep by Milwaukee over the weekend.

“We hit some balls hard. When we do square balls up, we’re not

catching much of a break. That’s for doggone sure. We just have to

move on,” manager Jim Tracy said after a 3-1 loss Sunday. “With

what’s going on with us right now offensively, it’s one situation

like that after another.”

The Rockies have totaled three runs in the last two games.

All-Star shortstop Troy Tulowitzki went 0 for 3 on Sunday and

has batted .174 over the last 22 games, during which Colorado has

gone 7-15.

Tulowitzki may not be looking forward to facing the

Diamondbacks, against whom he is hitless in 21 at-bats this season.

His career .223 average versus Arizona is his lowest against any NL

opponent.

The Rockies, 2-3 against the Diamondbacks this season, have

taken 12 of 15 meetings at Coors Field while averaging 6.5

runs.

Jorge De La Rosa (5-2, 3.34 ERA) will try to get the Rockies off

to a strong start to the doubleheader by continuing his dominance

over Arizona. The left-hander has gone 5-1 with a 2.03 ERA in his

last seven matchups with the Diamondbacks.

De La Rosa is coming off perhaps his best outing of the year,

pitching a five-hitter and giving up one earned run in a 2-1 loss

at Philadelphia on Wednesday.

“Everything was working,” he told MLB.com. “I’ve been working on

my pitches since spring training. I have to keep pitching like

that.”

Joe Saunders (0-5, 5.02) will oppose De La Rosa as he tries

again for his elusive first win of the season. He allowed one run

in six innings of a 5-4, 11-inning win over Atlanta on

Wednesday.

Saunders held the visiting Rockies to three runs in six innings

of a 4-3 victory May 3. He gave up seven runs – four earned – in 2

1-3 innings during his only start at Coors Field, a 13-4 loss Sept.

10 in which he opposed De La Rosa.

Jhoulys Chacin (5-2, 2.70), who limited Arizona to two runs over

seven innings to win 6-4 on May 4, takes the mound in the nightcap

while the Diamondbacks give the ball to Josh Collmenter (3-0,

0.69).

Chacin threw seven innings of one-run ball and struck out a

season-best nine in a 7-1 road victory over the Phillies on

Thursday. The right-hander has gone 2-1 with a 1.80 ERA in five

home starts this season.

Collmenter allowed two hits in six scoreless innings for the

second straight start – the second of his career – to beat the

Braves 2-1 on Thursday.

“You couldn’t ask for more,” manager Kirk Gibson said of the

right-hander. “Hopefully he’ll keep it going.”
