Burger is not in the lineup for Monday's game against the Diamondbacks.

The right-handed-hitting Burger was in the lineup against lefties in each of his first two games after being activated from the injured list Friday. However, he has now retreated to the bench in two straight contests versus righties. Lefty swinger Rowdy Tellez will receive a second straight start at first base Monday.

Horwitz is out of the lineup for Monday's game against the Brewers.

Horwitz batted leadoff in each of the last four games and got on base at a .389 clip while scoring two runs and driving in two more, but the Pirates haven't yet committed to using him regularly against left-handed pitching. With southpaw Jose Quintana on the hill for Milwaukee, the left-handed-hitting Horwitz will give way to the right-handed-hitting Liover Peguero at first base.

Pirates director of sports medicine Todd Tomczyk said Wednesday that Valdez (shoulder) has resumed playing catch out to 90 feet, Colin Beazley of the Pittsburgh Post-Gazette reports.

Valdez is at about the midway point in his recovery from May surgery to address a dislocated left shoulder. Though the 26-year-old isn't on track to return from the 60-day injured list before the end of the season, the Pirates are optimistic that Valdez will be available to play winter ball.

Dodgers manager Dave Roberts said Sunday that Hernandez (elbow) is pain-free and could be ready to return from the 10-day injured list in early September, Sonja Chen of MLB.com reports.

Less than a week ago, Roberts expressed some uncertainty whether Hernandez would be ready to return from the IL before season's end, but the 33-year-old utility player has evidently made some significant strides in his recovery from left elbow inflammation in recent days. According to MLB.com, Roberts said that Hernandez has reached a point in his rehab that he's able to ramp up his involvement in baseball activities. Hernandez has already done some throwing, running and fielding grounders, but swinging the bat without discomfort will be the major hurdle that he'll need to clear before heading out on a rehab assignment.

Walker went 3-for-4 with a double, an RBI and two runs scored Sunday against the Yankees.

Walker played a key role in a few of Houston's rallies Sunday, beginning with an RBI double in the third inning. The performance marked his fourth mult-hit game in his last 11 starts, during which he's gone 11-for-42 with three homers, 10 RBI and 10 runs scored.

Horwitz went 2-for-5 with a double, one run scored and one RBI on Sunday against the Reds.

Horwitz has had an inconsistent season as Pittsburgh's primary first baseman, but he's delivered throughout the early portions of August. He has gone 12-for-35 with two homers, nine RBI and eight runs scored across 10 starts in the month. Horwitz is now hitting .266 for the season, though he's provided very little pop with only a .124 ISO.

Schanuel went 2-for-5 with a two-run home run in Sunday's 9-5 loss to the Tigers.

Schanuel got the Angels on the board with a two-run homer in the fifth inning. It was an encouraging effort for the 23-year-old, who had been just 6-for-32 with one extra-base hit through eight August contests. For the year, he's slashing .272/.358/.396 with 10 home runs, 48 RBI, 57 runs scored and five stolen bases across 492 plate appearances.

Naylor went 1-for-2 with a solo home run and an additional run scored during Sunday's 6-3 win over Tampa Bay

Naylor hit his third home run in five games, taking Bryan Baker yard in the seventh inning. The first baseman has now recorded a hit in 10 of 15 games with the Mariners, going 15-for-52 (.288) with four homers, three doubles, 11 stolen bases and 10 runs scored. Naylor had stolen 11 bases in 95 games before being traded.

Olson went 2-for-3 with a solo home run, a walk and an additional run scored in Sunday's 7-1 win over the Marlins.

Olson got Atlanta on the board with a 419-foot blast in the fourth inning, marking his first homer since July 20. In 19 games between long balls, the first baseman hit just .247 with four doubles and five RBI. For the year, he's slashing .262/.363/.451 with 19 home runs, 70 RBI and 66 runs scored across 526 plate appearances.

Steer went 3-for-5 with a home run, a double, four RBI and two runs scored in Sunday's 14-8 win over the Pirates.

Steer fell a triple shy of the cycle, delivering a two-run double in the sixth inning and a two-run homer in the eighth. The 27-year-old has been streaky over his past 10 games, going hitless five times but still producing four multi-hit efforts, three home runs, 13 RBI and seven runs scored. For the year, he's slashing .241/.304/.398 with 14 long balls, 54 RBI, 49 runs scored and six steals across 431 plate appearances.
