Notes: Ortiz may be back Tuesday

TORONTO -- David Ortiz's injured right foot will keep him out of the Red Sox lineup on Monday, but Ortiz is hopeful he'll be available Tuesday if he continues to heal at the same rate.

"It's better than what it was last night or this morning," Ortiz said Monday afternoon. "[There's] nothing broken or anything, so once the inflammation goes away it should be fine."

Ortiz suffered the injury when he fouled a ball off his foot in the fourth inning of Sunday's 8-6 loss to the Mariners, describing it as "the worst" pain he'd ever felt from such an incident. He was able to finish that at-bat (a strikeout), but during his next plate appearance Ortiz had to be removed for a pinch-runner after hitting a long single that would've been a double had the slugger been fully healthy.

It appears as though Ortiz isn't a pinch-hitting option on Monday either, as Ortiz said he "can't put much weight on [the foot] yet." Ortiz is second to only Dustin Pedroia for games played this season, as Ortiz has appeared in 123 of Boston's 130 contests.

Mike Napoli will fill Ortiz's usual DH role on Monday, while Allen Craig will play first base for the first time since he was dealt to the Red Sox on July 31.

Other notes:

* The shoulder tweak that caused Joe Kelly to be removed early from his last outing appears to no longer be a problem for the right-hander. Manager John Farrell said Kelly is on pace to make his scheduled start on Wednesday against the Blue Jays.

"[Kelly] came through his bullpen yesterday in good shape, and at this point we don't anticipate any issues," Farrell said.

Kelly felt the discomfort during the fifth inning of his start last Friday, and he was removed for precautionary reasons. It was a sour end to an otherwise tremendous outing for Kelly, who allowed only one hit over his five shutout frames.

* After nine seasons in professional baseball, Carlos Rivero is finally a major leaguer. Xander Bogaerts was officially placed on the seven-day concussion DL on Monday, and the Sox filled the 25-man roster spot by purchasing Rivero's contract from Triple-A Pawtucket.

Rivero, a 26-year-old Venezuela native, hit .262/.320/.379 over 4092 minor league plate appearances in the Indians, Phillies, Nationals and Red Sox organizations. The utilityman saw time at third base, shortstop and left field in Pawtucket and he's also played first base and right in his career, making him a versatile bench option.

"I wasn't expecting it. It was a big surprise, a really happy surprise," Rivero said via an interpreter. "I'm very happy for the opportunity. It's been a long time. I'm going to keep working and see if I can stay as long as I can."
