It appears Rick Porcello is close to returning to the Boston Red Sox.

Porcello was placed on the 15-day disabled list on Aug. 2 with triceps soreness and inflammation after a rough first half of the season. He pitched 5 2/3 innings in a rehab stint for Triple-A Pawtucket on Friday, and it appears a bullpen session is the next step.

“This is a guy who you invested a lot of money in, who has had some problems, a little bit of an injury there — ineffectiveness, no question about that,” NESN’s Steve Lyons said of Porcello on “Red Sox Final” after Boston’s 6-3 loss to the Kansas City Royals. He’s got to get back up here and get himself a few more starts before the season’s over to right the ship going into next year.”
