ST. LOUIS — The Red Sox are set to make another roster move with their pitching staff before Tuesday’s game against the St. Louis Cardinals with the addition of Heath Hembree.
Hembree was one of the two prospects obtained in the trade of righthander Jake Peavy to the Giants on July 26. The 25-year-old righthander since has pitched two games for Triple A Pawtucket.
Hembree appeared in nine games for the Giants last season, throwing 7⅔ scoreless innings and striking out 12 with two walks. He entered this season ranked among the best prospects in the San Francisco organization.
The Red Sox added lefthander Tommy Layne and righthander Alex Wilson to their bullpen on Friday. Wilson threw 39 pitches over 2⅓ innings Saturday and was optioned back to Pawtucket.
Steven Wright, a starter, was called up for Sunday’s game against the Yankees in case a long reliever was needed. He was optioned after the game.
Now Hembree will get a chance.
The Red Sox also could add an outfielder on Tuesday. Corey Brown did not play for Pawtucket on Monday. Allen Craig has missed two games with an injured left foot and could require a stint on the disabled list. Craig has played one game for the Red Sox since being obtained Thursday.
Brown had 36 games of major league experience with the Nationals from 2011-13. He has hit .226 for Pawtucket with 16 home runs.
Lefthander Henry Owens made his Triple A debut in impressive fashion Monday, allowing two hits over 6⅔ scoreless innings against Columbus. The 22-year-old struck out nine and walked three.
Owens did not give up a hit until the sixth inning. He threw 100 pitches, 71 strikes.
Owens was 14-4 with a 2.60 ERA in 20 starts for Double A Portland.
The Red Sox also promoted 22-year-old catcher Blake Swihart to Pawtucket. He hit .300 with an .840 OPS in 92 games for Portland. Swihart was the 26th overall pick of the 2011 draft.
They meet again
Ex-Red Sox catcher A.J. Pierzynski has played six games for the Cardinals since he was signed on July 26. He is 6 of 22 with a double and two RBIs.
The Red Sox released Pierzynski on July 16. He hit only .254 for the Sox with 15 extra-base hits and 31 RBIs in 72 games. Outside of the prorated minimum, the Red Sox are responsible for all of Pierzynski’s $8.25 million salary this season.
The Cardinals are the fourth team Pierzynski has been with since the 2012 season.
Red Sox assistant general manager Mike Hazen remains a candidate to become the GM of the Padres. But Yankees assistant GM Billy Eppler may be the favorite for the job. Eppler, a San Diego native, was in Boston over the weekend for the Yankees-Red Sox series but did not accompany the team back to New York on Sunday night. Padres team president Mike Dee was in Boston over the weekend for the Pan-Mass Challenge and is believed to have met with Eppler on Monday . . . The Red Sox are 19-32 against AL East teams, 30-30 otherwise. The Sox are 6-6 in interleague games.Peter Abraham can be reached at email@example.com. Follow him on Twitter @PeteAbe.
