Taking the ball for the Padres will be Anthony Bass, who continues to adapt to life in the starting rotation. Though roughed up for six earned runs over six innings in his previous start against the Marlins, Bass has been effective since moving out of the bullpen in mid-April. The right-hander is 1-2 with a 3.68 ERA, 34 strikeouts and 13 walks in five starts (29 1/3 innings).
Though Bass' previous outing was a rocky one, Padres manager Bud Black found positives in the way he pitched.
"That's really a tribute to Anthony, the way he hung in there," Black said after the outing. "He was making pitches as he went along. I was proud of him for battling. A lot of pitchers would have caved in there."
Wednesday will be Bass' second look at Colorado this season. Bass allowed three earned runs on four hits with seven strikeouts over five innings in a loss on April 17.
While Bass continues to adapt to the starter's role, the Rockies will get a glimpse of a pitcher adjusting to life in the big leagues. Left-hander Christian Friedrich will make his Major League debut after starting the year 2-0 with a 3.00 ERA in five starts with Triple-A Colorado Springs.
Friedrich, the Rockies' 24-year-old first-round Draft pick in 2008, has battled through injuries and inconsistency during his Minor League career, but sought help from multiple veteran sources, including teammate Jamie Moyer, former All-Star Mike Hampton and the Phillies' Cliff Lee. Given his draft status and bumpy road through the Minors, Friedrich voiced his desire to prove he has been worth the investment.
"[The club was] probably excited in the beginning, but probably a little disappointed the last two years -- one year it was because of injuries and last year I just didn't have enough consistency," Friedrich said. "Getting up here is what I've wanted to do. This is what they've expected, and I hadn't met those expectations."
