Vaughn went 2-for-4 with two doubles and four RBI in Saturday's 6-5 win over the Nationals.

Vaughn has hit safely in all five of his games with Milwaukee, going 6-for-14 (.429) with four extra-base hits and 10 RBI. The first baseman delivered a pair of two-run doubles Saturday, with the second being a game-tying hit during the Brewers' ninth-inning comeback. Vaughn is slashing .206/.239/.362 with seven homers, 29 RBI, 10 doubles, 12 runs scored and no stolen bases over 209 plate appearances overall between the White Sox and Brewers this season, though he's taking full advantage of his opportunity to play while Rhys Hoskins (thumb) is on the mend.

The Reds are promoting Stewart to Triple-A Louisville, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Stewart will move one step closer to the majors after shining in Double-A ball, posting a .306/.377.473 slash line with 10 homers, 44 RBI, 51 runs and 13 stolen bases over 80 games. The 21-year-old also continued to show an excellent eye at the plate with a 15.5 percent strikeout rate. If Stewart continues to hit well with Louisville, he could get his first call-up to the majors later this season.

Burger (quad) isn't in the lineup for Saturday's game against the Astros.

Burger said after leaving Friday's game with quad discomfort that he expected to play in Saturday's contest. Instead, the Rangers will keep him on the bench to begin the game, and he could also sit out Sunday if the Rangers want to make sure he's at 100 percent coming out of the All-Star break. Ezequiel Duran will start at first base instead and bat ninth Saturday while Burger sits.

Mountcastle (hamstring) is expected to begin a rehab assignment at Triple-A Norfolk on July 22, Rich Dubroff of BaltimoreBaseball.com reports.

A Grade 2 right hamstring strain has kept Mountcastle on the injured list since the end of May. By beginning minor-league play July 22, the 28-year-old is still in a position to be activated when first eligible July 30, as he'll have more than a full week to ramp up in Triple-A.

Blanco (leg) began a rehab assignment with the Florida Complex League Pirates on Saturday, Anthony Murphy of DKPittsburghSports.com reports.

Blanco has been sidelined all season with a leg injury, but he should be nearing a return to Single-A Bradenton. He has excellent power potential but will need to display the ability to make more consistent contact to eventually make an impact in the majors.

The Reds optioned Encarnacion-Strand to Triple-A Louisville on Saturday.

Encarnacion-Strand has seen his playing time dwindle over the past several days, and Jake Fraley's (shoulder) return from the IL will now leave the former without a spot on the active roster. The 25-year-old Encarnacion-Strand has slashed .208/.234/.377 across 137 plate appearances this season.

Busch isn't in the lineup for Saturday's game against the Yankees.

Busch went 0-for-2 with two strikeouts and a walk in Friday's loss, putting an end to what had been a six-game hitting streak. He'll get a chance to refresh Saturday while Justin Turner starts at first base, batting eighth.

Schanuel went 3-for-4 with a walk, a double, a run scored and a stolen base in Friday's 6-5 win over the Diamondbacks.

After sitting out Thursday's game due to tightness in his left calf, Schanuel returned to his usual spot at first base and looked pretty healthy when he doubled in the eighth inning and then swiped third base. The 23-year-old has had a productive beginning to July, slashing .286/.354/.381 over 10 contests with a homer, a steal, three runs and seven RBI.

Santana went 1-for-4 with a walk, a two-run home run and a stolen base across both ends of Friday's doubleheader split with the White Sox.

The veteran first baseman clubbed the game-winning homer in the matinee, breaking a 2-2 tie by taking Tyler Alexander deep in the sixth inning, and while Santana began the nightcap on the bench, he drew a walk as a pinch hitter and swiped a bag in the 10th inning. Four of his six steals on the year, and three of his 11 long balls, have come in his last 20 games, a stretch in which Santana is slashing just .171/.275/.314 with nine runs and 10 RBI.

Smith went 1-for-4 with a solo home run in Friday's 8-7 win over the Dodgers.

Smith's solo shot in the fifth inning sparked a five-run rally for the Giants. This was his second homer with the team and the first at home. He's struggled with consistency at the plate lately, going just 3-for-21 (.143) over eight games in July so far. He's at a .244/.322/.385 slash line through 90 plate appearances this season while working in a timeshare with Wilmer Flores at first base.
