Veteran hurlers collide at Wrigley Field

( - Two veteran pitchers plus two losing teams plus one trade deadline.

Do the math.

Jorge De La Rosa and Edwin Jackson face each other on the mound Tuesday night in what could serve as a pre-acquisition when the Colorado Rockies meet the Chicago Cubs in game two of a four-game series at Wrigley Field.

Rockies ace De La Rosa is in the midst of a double-digit win season and becomes a free agent before the arrival of 2015, factors which make him a potential target for pitching needy teams. If no trade is made, Colorado would get a draft pick as compensation if it offers at least $14 million prior to him signing elsewhere.

The lefty gave up eight runs in his last loss against the Los Angeles Dodgers on June 18, but has since gone 5-0 in six starts with a 3.05 earned run average. In his last three starts, he's pitched at least six innings and given up no more than a single earned run.

"If I get traded, I get traded," De La Rosa said. "I don't have to think about those things right now."

In five career meetings with the Cubs, he is 3-0 with a 2.37 ERA.

As for Chicago, it can win two in a row for the first time since early in the month.

Jackson is in the midst of a four-year contract worth more than $50 million, and he's been lousy of late in game situations, going 0-4 with a 7.47 ERA since last winning on June 20.

He was raked for five runs in five innings in a 13-3 loss to San Diego at Wrigley on Thursday, and is 0-3 in his last four starts there with an ugly 11.57 ERA.

Eight matchups with the Rockies have yielded a 1-3 mark and a 12.66 ERA.

Possible good news for Jackson: Colorado has dropped seven straight on the road -- its longest streak in two seasons -- while scoring only 15 runs.

On Monday, Tsuyoshi Wada pitched seven innings to lead the Cubs to a 4-1 win over the Rockies.

Wada (1-1) notched his first career win after giving up just one run on five hits with a walk and six strikeouts in seven innings for the Cubs. Anthony Rizzo drove in two runs in the win.

Yohan Flande (0-3) is still looking for his first win after allowing two runs on four hits in 6 2/3 innings for the Rockies.

Colorado and Chicago split six meetings last season.
