Houston optioned Whitcomb to Triple-A Sugar Land on Thursday.

The Astros made a flurry of acquisitions ahead of Thursday's trade deadline that led to Whitcomb losing his spot on the 26-man active roster. The 26-year-old infielder is closing in on his third season in a row with 20-plus homers and double-digit steals at the Triple-A level, but he has a career .178 average and .231 on-base percentage in 78 plate appearances in the big leagues.

Riggio was traded from the Yankees to the Rockies on Thursday along with Ben Shields in exchange for Jake Bird, Jeff Passan of ESPN.com reports.

Riggio's minor-league numbers may oversell his abilities, as he's typically been old for the levels he's had success at, but now that he could get to play half his games in Coors Field, his dynasty value gets a little bump. The 23-year-old second baseman is slashing .261/.335/.542 with 11 home runs, seven steals, a 7.6 percent walk rate and a 21.8 percent strikeout rate in 40 games since getting promoted to Double-A on June 3.

Chisholm went 1-for-5 with two stolen bases in a 5-4, extra-innings win against the Rays on Wednesday.

Chisholm singled and proceeded to steal both second and third base in the fourth inning but was stranded without crossing the plate. However, he scored the winning run in the 11th frame after beginning on second as the automatic runner. The thefts were Chisholm's first since June 10 -- a span of 40 games. While he hasn't been as active on the basepaths this season, his .813 OPS is on pace for the second-best mark of his career.

Lowe went 2-for-4 with a double, an RBI and a walk Wednesday against the Yankees.

Lowe returned from the injured list after a minimum stint and hit second in the order. He doubled in a run in his second at-bat and followed that up with a single in the fifth inning. Lowe has hit .315 with eight home runs, 20 RBI and 25 runs scored across 34 games since the start of June, and he should play nearly every day across the last two months of the season if he can stay healthy.

The Rays optioned Gray to Triple-A Durham on Wednesday.

The move makes room on the 26-man roster for Brandon Lowe (foot), who was reinstated from the 10-day injured list. Gray was acquired by the Rays from the White Sox on Saturday, and he has spent most of the season at the Triple-A level, where he slashed .270/.333/.472 with three steals, four triples, nine home runs and 44 RBI across 282 plate appearances.

The Rays activated Lowe (foot) from the 10-day injured list Wednesday, Ryan Bass of FanDuel Sports Network Sun reports.

Lowe required just the minimum 10 days on the IL while recovering from plantar fasciitis in his left foot. He is starting at second base and batting second in Wednesday's contest against the Yankees in what could be his final game in a Rays uniform prior to Thursday's trade deadline. Tristan Gray was optioned to Triple-A Durham in a corresponding move.

Urias isn't in the lineup for Wednesday's game against the Mariners.

Urias will sit down for Wednesday's series finale after going 1-for-6 with a run scored over the Athletics' last two games against Seattle. Max Schuemann will shift to second base to cover for Urias while Darell Hernaiz starts at shortstop.

Edman is out of the lineup for Wednesday's contest in Cincinnati.

Edman homered Tuesday in his return to action after missing Monday's game with an ankle injury. The Dodgers haven't provided any indication that Edman suffered a setback, so his absence Wednesday appears to be a measure of giving him two days of rest since the team is off Thursday. Miguel Rojas will start at second base and Alex Freeland will man third base for the Dodgers in the series finale in Cincinnati.

Iglesias will start at shortstop and bat seventh in Wednesday's game against the Mets.

Iglesias has now started in five of the Padres' last six games and has maintained a solid, if unspectacular .278/.333/.361 slash line with three extra-base hits (all doubles), two stolen bases, five runs and one RBI since the All-Star break. Though he's performed well enough to retain a near-everyday spot in the lineup for the time being, Iglesias will be at risk of moving into more of a utility role if the Padres add another impact bat ahead of Thursday's trade deadline.

Matthews is out of the lineup for Wednesday's game against the Nationals.

Since slugging three home runs and driving in seven runs in his first six big-league games, Matthews' production has fallen off considerably. In his last five contests, Matthews has gone just 1-for-15 with nine strikeouts, and his ongoing struggles appear to have resulted in him moving into more of a part-time role. He'll be on the bench Wednesday for the fourth time in six games.
