A's acquire Pomeranz, Jensen

The Oakland A's acquired Minor League hurlers Drew Pomeranz and Chris Jensen on Tuesday, sending starter Brett Anderson to the Colorado Rockies.

Pomeranz was the fifth overall pick (by the Indians) in the 2010 Draft out of the University of Mississippi. Traded to the Rockies for Ubaldo Jimenez in August 2011, the left-hander made his Major League debut that September.

Ranked as the No. 24 prospect in baseball going into the 2012 season, Pomeranz has had limited success at the big league level: he's 4-14 with a 5.20 ERA in 34 big league outings (30 starts) over the past three seasons. Pomeranz was 0-4 with a 6.23 mark for the Rockies in 2013, fanning 19 and walking 19 in 21 2/3 innings.

The 25-year-old fared better in Triple-A, posting an 8-1 record with a 4.20 ERA in 15 starts for Colorado Springs this past season, striking out 96 over 85 2/3 frames.

Jensen, who turned 23 in September, was a midseason All-Star in the California League in 2013, going 5-8 with a 4.55 ERA in 28 starts for Modesto. A sixth-round pick out of the University of San Diego in 2011, the right-handed Jensen ranked fifth in the Cal League with 136 strikeouts in 152 1/3 innings. His ERA was 10th-best among qualifying hurlers on the offense-minded circuit.

Anderson, 25, broke into the Majors as a 21-year-old in 2009, finishing sixth in AL Rookie of the Year voting after going 11-11 with a 4.06 ERA. Injuries have plagued the left-hander, however, limiting him to just 22 appearances (11 starts) over the past two seasons. After trading for the Midland, Texas, native, the Rockies will obviously pick up Anderson's $8 million club option for 2014. He has a $12 million club option for 2015 or a $1.5 million buyout. The A's are sending $2 million to Colorado to cover some of the $9.5 million in guaranteed money heading Anderson's way.
