Wilson called up to spell taxed bullpen

BOSTON -- In need of another bullpen arm after two shaky starts by the team's starting rotation, the Red Sox decided to recall reliever Alex Wilson from Triple-A Pawtucket on Wednesday.

The Red Sox's bullpen has been taxed in the past two games, as six different pitchers have tossed seven innings.

"We felt like a two-inning reliever is what we needed, which Alex has done. He has a familiarity with the role and that is why he is here," said manager John Farrell.

While the right-hander is expected to be with the club for only a small chunk of time, he's going to do his best to stand out.

"I'm not sure how I'm going to be used, but I'm just going to try to provide a consistent arm while I'm here and hopefully it will be longer than shorter," said Wilson.

Wilson's held right-handers to a .063 average with Pawtucket this season. Opponents are also 0-for-7 with runners in scoring position against him this season.

With the Red Sox in 2013, Wilson went 1-1 with a 4.88 ERA in 26 games. He struck out 22 batters in 27 2/3 innings.

"It's always a confidence boost. It's always great to come back. It definitely makes you feel good," Wilson said. "Every time out, I feel like it's an audition for me to keep proving to everybody what I can do."

After quick start, Sizemore sputtering at plate

BOSTON -- The Red Sox came into the season well aware that it would be a year of ups and downs for Grady Sizemore.

Before signing with the Red Sox in the offseason, he'd been out of baseball for two years after recovering from microfracture surgery on his right knee.

Back on April 15, Sizemore was hitting .308 with two home runs and four RBIs. Coming into Wednesday's game against the Yankees, had just one hit since then, a span of seven games.

It's easy to assume that Sizemore has hit a wall, but manager John Farrell believes there's more to it.

"When he's squared up some balls, it hasn't quite traveled to what we might expect," Farrell said. "We aren't seeing an abnormal amount of swing and miss. The bat speed is there. I don't see him coming out of an approach or doing more than he is capable of.

"We have to keep in mind that he's compiling a decent amount of at-bats and with a large gap of playing time. I don't see anything from a mechanics standpoint."

Over the past 11 games, the Red Sox have also decided to mix up the alignment in the outfield, putting Jackie Bradley Jr. in center field and Sizemore in the corner outfield spots. Sizemore was in right field for Wednesday's game.

"We recognize that he's not as comfortable in the corner outfield spots as he would be in center," said Farrell. "Through the repetition, we see him more in the corner spots than in center at this point. We are doing what we can to shorten down that curve so he is more efficient."

Boston Marathon winner tosses out first pitch

BOSTON -- The Red Sox honored Meb Keflezighi, the men's winner of the 118th Boston Marathon, before Wednesday's game against the Yankees.

Keflezighi took the hill to throw out the ceremonial first pitch.

The 38-year-old became the first American to win the race since 1983 by completing the 26.2-mile course in a time of two hours, eight minutes, 37 seconds.

Keflezighi got a big hand from the crowd, waved to them, tipped his hat and then fired a pitch to Jonny Gomes. Keflezighi was wearing a Boston Strong hat and a Red Sox jersey that had 26.2 on the back.
