Smith (hamstring) will play in one more rehab game with Triple-A Buffalo on Saturday, Arden Zwelling of Sportsnet.ca reports.

Assuming Smith comes out of his third rehab game without any issues, he will rejoin the big-league club and officially return when rosters expand Sept. 1. Smith has endured a tough season between Texas and Toronto, but his versatility around the diamond will likely afford him occasional opportunities with the Blue Jays down the stretch.

McMahon (thumb) will begin a rehab assignment with Double-A Somerset on Saturday, Gary Phillips of the New York Daily News reports.

Manager Aaron Boone explained that McMahon will "probably" play in just one game before rejoining the Yankees, with the plan being to activate the infielder when rosters expand Sept. 1. The 31-year-old McMahon has mostly struggled at the dish in the years since he left Colorado, though his defense at the hot corner is still valuable enough to project him for a semi-regular role upon his return to the active roster.

House went 1-for-4 with a three-run home run in Friday's win over the Marlins.

The third baseman absolutely crushed a grooved fastball from Eury Perez in the third inning, sending it 445 feet to left-center field to break open the game in an eventual 9-2 victory. It was House's 10th homer of the season but his first since Aug. 15. Since returning to the majors in late July, he's put together a tepid .244/.317/.400 slash line with five doubles, three long balls, 11 runs and 11 RBI in 28 contests.

Karros (concussion) has resumed both hitting and fielding drills at the Rockies' complex in Arizona, MLB.com reports.

Karros has dealt with a concussion or concussion symptoms for nearly three weeks, and he attempted to return once already. The next step in his recovery will be a simulated game Saturday.

Koss went 1-for-3 with a two-run home run in Friday's 10-6 loss to the Diamondbacks.

Koss has gone 16-for-60 (.267) over his last 18 games, adding a homer and four doubles in that span. The infielder has taken over a starting role at shortstop in the absence of Willy Adames (elbow), who could miss the rest of the season after going down with the injury Sunday. Over 123 plate appearances this season, Koss is batting .211 with a .537 OPS, one homer, four RBI, 12 runs scored, five doubles and two stolen bases, so he's unlikely to hit his way into the picture in fantasy.

Gelof went 2-for-4 with one RBI and one stolen base in Friday's 4-3 extra-inning loss to the Orioles.

Gelof has gone 6-for-41 (.146) over his last 11 games. The utility man is up to 10 steals on the season, including two in that 11-game sample. He's added a .258 average, .775 OPS, 14 home runs, 38 RBI, 53 runs scored, 13 doubles and one triple over 84 contests this year. Gelof is primarily working at third base with some other starts coming in left field or at second base.

Mayo went 2-for-4 with one RBI, one stolen base and one run scored in Friday's 4-3 extra-inning win over the Athletics.

Mayo has gone 10-for-36 (.278) with three homers and seven RBI over his last 10 games. The infielder continues to get steady playing time between designated hitter and the infield corners, though he's not quite an everyday player given the crowded competition in those spots. For the year, he's batting .216 with a .721 OPS, 18 homers, 52 RBI, 49 runs scored, 13 doubles, three triples and three stolen bases over 107 contests.

Okamoto went 2-for-3 with a home run and three RBI during the Blue Jays' 8-1 win over the Mariners on Friday.

Okamoto contributed to the Blue Jays' three-run first inning with a sacrifice fly that brought Vladimir Guerrero home. Okamoto kept his night going with a solo homer in the sixth -- his 27th home run of the season -- while adding an RBI single in the seventh. It was the eighth time this season that he drove in at least three runs in a game, and his 77 RBI is 10th-most in the American League this season.

Arenado (thumb) will start at third base and bat fifth Friday against the Giants.

Arenado was left off the first version of Friday's lineup, but he is now seemingly unbothered by the thumb inflammation that caused him to sit out Thursday, so he'll check back into the starting nine. The veteran third baseman has been in a bit of a slump recently, going 5-for-27 (.185) with eight strikeouts across his last seven games.

Arenado (thumb) isn't in the lineup for Friday's game against the Giants.

Arenado was a late scratch Thursday due to thumb inflammation, and he'll need at least one more day off to recover. Jose Fernandez will pick up another start at third base and bat sixth.
