Red Sox prospect Matt Barnes has delievered a 1.96 ERA over his last four starts with Double-A Portland, WEEI.com reports Saturday.

On Friday, Barnes allowed three runs on five hits with seven strikeouts over six innings. He walked a batter. He's got 28 strikeouts with seven walks over his last 23 innings for that 1.96 ERA.

The Orioles officially recalled Jair Jurrjens to start Saturday at Camden Yards against the Tampa Bay Rays.

In eight starts for Triple-A Norfolk this season, Jurrjens has registered a 4-1 record and 3.14 ERA while displaying improved command.

Giants infielder Marco Scutaro continues to tear the cover off the ball, going 3 for 5 in Friday's 10-9 loss to the Rockies. Scutaro scored one run and drove in another, while striking out once.

Scutaro is batting .475 in the month of May, with 11 multi-hit games in 14 games. He currently has a 16-game hitting streak active. 

Mariners starter Felix Hernandez received further medical clearance from manager Eric Wedge on Saturday, MLB.com reports. Hernandez is a full go for Sunday's start against the Indians.

Hernandez tweaked his back Tuesday against the Yankees, but has been expected to make Sunday's start all week.

Hernandez is 5-2 with a 1.53 ERA for the Mariners.

As expected, Reds pitcher Tony Cingrani was optioned to Triple-A Louisville Saturday, after it became clear he would not remain in the rotation upon Johnny Cueto's return. The team recalled infielder Neftali Soto to take Cingrani's place in the rotation.

Cingrani went 2-0 with a 3.27 ERA in six starts before being sent down. He struck out 41 batters in 33 innings. 

The Reds called up infielder Neftali Soto from Triple-A Louisville prior to Saturday's game against the Phillies, according to MLB.com.  A corresponding move has yet to be announced, but it appears that pitcher Tony Cingrani will be optioned to Louisville.  

Soto batted .269 with three home runs and 16 RBI in 33 games at Triple-A. 

Cubs starting pitcher Matt Garza is set to make his first start of the season Tuesday against the Pirates, and he is understandably excited to be over his lat injury.

"I'm happy I don't have to rehab again," he told the Chicago Sun-Times Saturday. "I just had to refresh some stuff from spring training, got the rust off. I feel great, ready to go Tuesday and can't wait."

Garza has not pitched in a major-league game since July 28, when he was shut down with a stress reaction in his right elbow. He admitted to being a bit worried when he first took the mound in Double-A Tennessee, his first competitive action in eight months.

"The only time I was nervous was when I made my first rehab in Tennessee," he said. "The first couple pitches I was a little worried, but then it was fine. Ever since then, there's been no doubt in my mind."

Garza threw six strong innings in his last rehab start, and he needed just 75 pitches to do so. The team expects him to be ready for a full workload quickly. 

The Orioles pushed second baseman Brian Roberts (hamstring) to the 60-day disabled list, MLB.com reports Saturday.

Roberts' move creates roster space for Jair Jurrjens to be added to the 40-man roster. Jurrjens is starting Saturday against Tampa Bay.

The Orioles placed outfielder Nolan Reimold on the 15-day disabled list on Saturday. Reimold has a right hamstring strain, MLB.com reports.

Reimold's DL stint will be backdated to May 11, when he last appeared in a game in Minnesota. He's batting .188 with four homers and nine RBI.

Chris Dickerson will continue to see more playing time in Reimold's absence.

The Orioles recalled Jake Arrieta from Triple-A Norfolk. Arrieta will presumably be used out of the bullpen, MLB.com reports.

Arrieta was optioned to the minors due to poor performance and command.

He worked on things with Norfolk and went 2-1 with a 2.75 ERA over three starts with 17 Ks over 19 2/3 innings. He only walked three batters.
