Newcomers to be assigned to Pawtucket

ST. PETERSBURG, Fla. -- Red Sox general manager Ben Cherington said that the two minor-league pitchers the Red Sox acquired from San Francisco Saturday for veteran Jake Peavy will be assigned to Triple-A Pawtucket.

Left-hander Edwin Escobar, 22, will join the PawSox rotation, Cherington said, after going 3-8 with a 5.11 ERA for Fresno in the Pacific Coast League, striking out 96 and walking 37 in 111 innings. Escobar pitched in the All-Star Futures Game.

Right-hander Heath Hembree, 25, who was 1-3 with 18 saves and a 3.89 ERA for Fresno, with 46 strikeouts in 41 innings, will go to the PawSox bullpen. Hembree pitched in the Triple-A All-Star Game.

Here were Cherington’s comments on both:

On Escobar:

“A physical left-handed pitcher with three pitches, he’s risen pretty quickly through their system. He’s performed really well as a young pitcher in the PCL. A couple of bumps in the road this year, not atypical for a young pitcher in the PCL. We like his physicality, we like he’s left-handed with three pitches. Good peripherals, even though his ERA is higher. He can pitch with his fastball and get misses. We like his chances to be a good major-league pitcher. He probably needs a little more time in Triple-A. He gets added to a group of young starting pitching prospects.’’

On Hembree:

“A little older, a little further along on development. He’s had a little major-league experience. He’s a reliever. We see him as a reliever. A heavy fastball, sinker. Sort of a classic reliever look, a big physical guy with a high strikeout rate throughout his minor league career, which we value, the ability to miss bats. He’ll go to Triple A initially and go into the bullpen there. He’s a guy we see competing for a spot in our bullpen at some point in the future.’’
