Five days after orchestrating a three-team, seven-player deal, the Red Sox will get to see the fruits of their labor Saturday when Jake Peavy takes the mound to make his Boston debut.
Although the right-hander will start at Fenway Park for just the second time in his 12-year career, Peavy will face a familiar foe in the D-backs, who won Friday's weekend opener and will look to clinch their first series win since the All-Star break.
Once a long-time Padre, Peavy has started 29 games vs. Arizona, the most of any team he's faced, with the 32-year-old compiling a 13-12 record and a 4.66 ERA. Saturday, however, will only be Peavy's third outing since suffering a broken rib in early June. He beat the Braves in his first start back, and then on July 25, he won a second consecutive game by limiting the Tigers to four runs on four hits over seven innings.
Still, even with Peavy's arm presumably all the way back after throwing 118 pitches against Detroit, the Red Sox and manager John Farrell will be cautious with their new starter.
"The stress of the pitches that he throws [Saturday] will have an effect on how deep he goes," Farrell said. "But I know after being down six weeks he threw a couple bullpen [sessions], he went out on rehab, he jumped up pretty quick in his pitch count. So his last start I think he threw 117 or right around there. It was a quick advancement to that number. There's not a number that says he has to come off the mound [Saturday]. But like every starter, we'll monitor it close and we'll see how his stuff is playing against Arizona."
Opposing Peavy for the D-backs will be Patrick Corbin, who took a hard-luck loss his last time out. The All-Star allowed just one run to the Padres over eight stellar innings Sunday, but he received no support and took his second loss.
"Most of the time, if I give up one run, we're going to get the win," Corbin said after the game. "Today just wasn't our day."
After surrendering a season-high five earned runs on July 2, the 24-year-old has given up just four runs in four starts over 28 2/3 innings since, good enough for a 1.26 ERA.
Red Sox: Morales progressing
On the 15-day disabled list with a left pectoralis strain, Franklin Morales will throw in back-to-back games for Triple-A Pawtucket on Saturday and Sunday.
Morales' rehab stint has been successful so far as he pitched Monday and Wednesday and recorded a scoreless inning in both outings. Farrell said he'd like to see Morales build up some more endurance before he returns, however.
"Well, the one thing we have to do and just my view is that he's thrown two innings of I think 13 and 15 pitches, so we'd love to say that when he comes back to us he'd be that efficient, but I think you still have to get him a little extended," Farrell said. "He's had such a start-and-stop year that we want to be sure that he's at least answered a few questions in this rehab assignment he's on right now."
D-backs: Montero visiting specialist
Miguel Montero, who was placed on the disabled list Thursday with lingering back issues, was scheduled to see Dr. Chris Yeung, the team's spine specialist, in Phoenix on Friday.
D-backs general manager Kevin Towers said the team was hoping to learn whether anti-inflammatory medication or an epidural shot would be better treatments.
"We're not going to bring him back if he's not ready to be 100 percent," D-backs manager Kirk Gibson said. "That's why we put him on [the disabled list] and we'll have to wait until it's fully gone."
• Boston is 19-1 when scoring first at home in 2013.
• The D-backs are 3 1/2 games behind both the Dodgers in the National League West and the Reds for the second Wild Card spot.
