The Colorado Rockies can pick up their first series sweep of the season when they wrap up a three-game set at the Pittsburgh Pirates on Wednesday afternoon. The Rockies dropped their first two road games of the season but are 9-2 away from home ever since, including a 6-2 win in the series opener at Pittsburgh and a 2-0 triumph in the middle game Tuesday.

Chad Bettis lowered his ERA to 1.44 as he spun 7 1/3 scoreless innings in Tuesday's win for Colorado, which has held opponents to an average of 2.5 runs through the first six games of its seven-game trip. The announced attendance was fewer than 9,000 for the game as the teams played in snowy conditions, but warmer and sunnier conditions are expected for the series finale. The Pirates hope that the improving weather helps their bats warm up as well, as they've managed nine hits and four walks through the first two games of the series. Right fielder Gregory Polanco was hitless in three at-bats Tuesday and is 1-for-19 in five games since he slugged two homers at Wrigley Field last Thursday.

Freeland gave up four runs in 10 2/3 innings over his last two starts and he kept the ball in the park at Washington on Friday after giving up two homers in each of his first two appearances. The Denver native was reached for five runs on nine hits in 5 2/3 frames of a start at Pittsburgh last season.

He was a bit better in his lone home start by allowing two runs in five frames while striking out seven against Cincinnati on April 7. The 25-year-old lost his first two career starts against Colorado while giving up seven runs in 11 innings.
