Schunk went 0-for-1 Saturday against the White Sox.

Schunk entered Saturday's game as a pinch hitter in the ninth inning to make his major league debut. He had his contract selected Friday, though it's unclear how much playing time he'll receive with Brendan Rodgers and Ryan McMahon locked in as starters at his positions.

Vientos went 2-for-4 with a solo home run and an additional run scored in Saturday's 9-6 loss to the Astros.

Vientos has flexed his power recently with five homers over his last nine games. In that span, he's batting .324 (12-for-37) with seven RBI and 10 runs scored. The third baseman is at a .297/.355/.578 slash line with 10 long balls, 23 RBI, 24 runs scored, no stolen bases and six doubles through 141 plate appearances this year. As long as the 24-year-old continues to hit well, he should have no trouble holding onto a starting job at the hot corner.

Manager Pat Murphy said Saturday that Dunn has a disc issue in his back and is expected to remain on the injured list for at least another month, Todd Rosiak of the Milwaukee Journal Sentinel reports.

Dunn landed on the MLB injured list Wednesday after originally being sent to Triple-A on June 19, and it now seems that he'll be stuck on the IL for an extended period of time. The 26-year-old infielder hadn't been playing very often anyway prior to landing on the IL, and he'll likely be optioned to Nashville again once he's fully recovered.

Ortiz was scratched from the Brewers' lineup ahead of Saturday's game versus the Cubs due to neck soreness.

Ortiz was originally in line to make his return to Milwaukee's lineup after neck problems kept him from playing Friday, but he'll instead require another day to heal. As a result, Andruw Monasterio will pick up another start at third base and bat ninth.

Ortiz (neck) will start at third base and bat leadoff during Saturday's game versus the Cubs.

Ortiz made an early exit from Wednesday's game versus the Rangers and sat out Friday's series opener due to neck problems, but he's feeling well enough to play Saturday. The 25-year-old third baseman has found a good amount of success at the plate recently, going 5-for-14 with a solo home run over his last five games.

Muncy (oblique) took swings off a tee, fielded groundballs and did some throwing Friday, Mike DiGiovanna of the Los Angeles Times reports.

Muncy's progress from a Grade 1 right oblique strain has been slow to the extent that he was transferred to the 60-day IL on June 21. However, the third baseman appears to be beginning to ramp up, and the Associated Press reports that his next step will be to take live batting practice before potentially beginning a rehab assignment. Muncy isn't expected to return to the Dodgers' lineup until after the All-Star break.

Candelario (hamstring) isn't in the Reds' lineup for Saturday's game against the Cardinals.

Manager David Bell said Friday that Candelario is trending toward a return for Sunday's series finale, so it isn't too surprising to see the 30-year-old infielder absent from Saturday's lineup. Spencer Steer will once again get the nod at first base, and Noelvi Marte will cover the hot corner.

Chapman went 1-for-4 with a two-run home run and a stolen base in Friday's 5-3 win over the Dodgers.

Chapman's power has come back, as he has three extra-base hits -- including two homers -- over his last five games. The third baseman gave the Giants their first lead Friday with his sixth-inning blast. For the season, he's up to 10 homers, 35 RBI, 53 runs scored and seven steals while posting a .235/.316/.399 slash line over 80 contests.

Candelario (hamstring) is on track to play Sunday against the Cardinals, Mark Sheldon of MLB.com reports.

Candelario hasn't played since Tuesday as he tends to hamstring tendinitis. However, he's set to make his return for the series finale Sunday and will avoid a stint on the IL. In his stead, Noelvi Marte should continue to start at third base while Spencer Steer handles first base work, but it's not yet clear how the workload at the infield corners will be divided between the trio once Candelario is healthy.

Ortiz (neck) is not in the starting lineup for Friday's series opener against the Cubs.

Ortiz has been dealing with a neck injury since last week's series against the Angels, and he was removed in the sixth inning of Wednesday's game against the Rangers after going 0-for-2. Despite having a day off Thursday, Ortiz will be in the dugout for at least the series opener against Chicago. Andruw Monasterio will start at third base Friday and bat ninth against Cubs right-hander Jameson Taillon.
