Darnell McDonald has been designated for assignment by the Red Sox in order to make room on the 25-man roster for Saturday night's starting pitcher, Josh Beckett.

Saturday afternoon McDonald (@MacDime54) tweeted: "Dream come true to play in Boston want to wish my boys good luck the rest of the year! Much love to RSN! ‪#ShowGoesOn"

Cody Ross is having the career year that no one is noticing. In the process, he is doing his best to demolish the logic behind the criticisms of the Red Sox’ most controversial roster move of the offseason.

Aaron Cook required just 81 pitches to sail through a two-hit, complete-game shutout in leading the Red Sox to a 5-0 victory over the Mariners. It was the first complete game for Cook since 2010 and his first shutout since 2009, in a dazzlingly efficient outing that hearkened to his All-Star prime.

Red Sox pitcher Daniel Bard had perhaps his worst outing since being sent back down to Triple-A Pawtucket, retiring just one of the six batters he faced after coming into the game for the top of the seventh inning against Charlotte, the Triple-A affiliate of the White Sox. Bard permitted a leadoff single and steal, and after getting a fly out, walked one batter, hit another, then walked two more to force in a pair of runs. He threw just nine of 26 pitches for strikes.

After nine minor league appearances, Bard has a 7.15 ERA with 14 strikeouts and eight walks in 11 1/3 innings.

The Red Sox will look to build on Friday night’s 5-0 win when they take on Mariners rookie right-hander Erasmo Ramirez on Saturday night. The 22-year-old is 0-2 with a 4.18 ERA and will be making his fourth career start.

Sox manager Bobby Valentine will use the same lineup for a third straight game, having come off a victory in which his offense belted four home runs. The Red Sox will be looking for that same success behind Josh Beckett, who will make his return to the mound after being placed on the DL for shoulder inflammation. 

Here is the Red Sox' lineup:

Red Sox outfielder Jacoby Ellsbury, in his first game since suffering a shoulder subluxation on April 13, went 1-for-4 with a double, walk and strikeout in five plate appearances for the Rookie Level Gulf Coast League Red Sox, who were playing the Twins in Fort Myers. Ellsbury served as the designated hitter. Fellow rehabber Carl Crawford went 0-for-2 with a pair of walks and a strikeout in six innings while catching a few fly balls in left field.

Making his weekly appearance on the Mut and Merloni appearance Friday, with Mike Mutnansky and guest co-host Kirk Minihane, former Red Sox Kevin Millar surmised that if Terry Francona was still managing the Sox the timetable for the Kevin Youkilis might have been different.

ESPN analyst Andy Katz, in an interview on the Dennis & Callahan Show, suggested that the Celtics did extremely well to grab Ohio State forward Jared Sullinger with the No. 21 overall pick in the draft. While there are medical issues surrounding the two-time All-American, Katz suggested that the opportunity to grab a player who might have been a lottery pick was rare.

PAWTUCKET -- The Red Sox signed Andy LaRoche, who requested and was granted his release by the Indians last week. The third baseman joined Triple-A Pawtucket on Thursday.

LaRoche, 28, played 46 games for Triple-A Columbus, hitting .234 with a .331 OBP, .372 slugging mark and .704 OPS, playing 30 games at third base and 10 more at shortstop. In 403 career big league games (most recently, two score with Oakland last year), he's a career .226/.305/.337/.642 hitter.
