Rays manager Kevin Cash said after Wednesday's 6-2 loss to the Marlins that Palacios is nursing a hyperextended right knee and is considered day-to-day, Marc Topkin of the Tampa Bay Times reports.

Palacios was lifted from Wednesday's game against the Marlins after just two innings with the injury. Cash noted that the utility player will be re-evaluated Thursday before the team heads out on its road trip, but at least for the time being, Palacios looks to have avoided a serious injury.

The Rays announced that Palacios was removed after two innings in Wednesday's game against the Marlins due to right knee discomfort, Marc Topkin of the Tampa Bay Times reports.

In his lone plate appearance in the bottom of the second inning, Palacios reached base on a walk, then proceeded to steal his 19th base of the season. Palacios looked to have injured his knee while sliding into second, but he was able to stay in the game and ultimately came around to score on Jonny DeLuca's RBI triple. However, Palacios remained in the dugout when the Rays took the field for the top of the third, with Dylan Carlson coming off the bench to replace him in left field. The Rays are viewing Palacios as day-to-day, and the team should have a better feel for his status heading into this weekend's series in Houston following Thursday's team off day.

The Red Sox optioned Westbrook to Triple-A Worcester on Wednesday, Ian Browne of MLB.com reports.

Westbrook saw regular reps at second base against left-handed pitching but did little with them, going just 2-for-22 at the plate this month. Nick Sogard was called up from Triple-A Worcester and will replace Westbrook on the 26-man active roster as the short-side platoon mate for David Hamilton at the keystone.

Palacios was removed from Wednesday's game against the Marlins with an apparent lower-body injury, Marc Topkin of the Tampa Bay Times reports. He walked in his lone plate appearance, stole his 19th base of the season and came around to score a run before exiting the game.

Palacios appeared to hurt his knee while sliding into second base on the steal. Though he was able to stay in the game and scored on Jonny DeLuca's RBI triple, Polanco ultimately remained in the dugout when the Rays took the field for the top of the third. Dylan Carlson came off the bench to play left field in place of Palacios, who can be considered day-to-day until the Rays provide an update on his status.

Castro is out of the lineup for Wednesday's game against the Mets.

Castro will exit the starting nine for the first time since July 10, breaking a streak of 13 consecutive starts. The versatile 27-year-old has picked up 10-plus starts at five different positions this season, but he's been seeing most of his action at second base of late following Edouard Julien's demotion to Triple-A St. Paul last week.

Gelof went 2-for-3 with a walk in a win over the Giants on Tuesday. He was also caught stealing twice.

Gelof's small-ball production stood in stark contrast to that of his teammates, as the Athletics scored all five runs off home runs. The multi-hit effort was an especially welcome sight for Gelof, who entered the night mired in a 1-for-25 slump that had encompassed his previous seven games. Gelof had last tallied multiple hits in a game July 9, and despite Tuesday's success, his average remains just below the Mendoza Line at .196 due to his recent skid. The pair of failed steal attempts were an outlier as well, considering Gelof had gone an impressive 12-for-13 in that category this season coming into Tuesday.

Baldwin is out of the lineup for Wednesday's game against the Royals.

Baldwin will get his first day off since he was promoted from Triple-A Charlotte earlier this month. The rookie infielder has had a tough time getting going in his first taste of the majors, going 7-for-40 with a 15:2 K:BB in 12 games. Lenyn Sosa will start at second base for the White Sox on Wednesday.

Massey is absent from the lineup for Wednesday's game versus the White Sox.

The White Sox have a right-hander in Drew Thorpe on the rubber, but the left-handed-hitting Massey will nonetheless begin the contest on the bench. With Massey out of the lineup, Freddy Fermin will serve as the Royals' designated hitter, while Maikel Garcia starts at second base.

Polanco went 2-for-4 with a solo home run, an RBI double and two additional runs scored during Tuesday's 10-6 win over the Red Sox.

Polanco lifted his 10th homer of the season Tuesday, tagging James Paxton for a solo shot in the fourth inning. The second baseman has been hot at the plate, clubbing four homers in his last five games and going a combined 7-for-19 with eight RBI and eight runs scored during that stretch. On the year, Polanco has recorded career worsts in OPS (.649) and strikeout rate (30.5 percent).

Lopez went 2-for-3 with a triple, two runs scored and a walk Tuesday against the Royals.

Lopez led off for the third straight contest and has tallied at least one hit on each occasion while scoring three runs. He has just a .049 ISO across 320 plate appearances for the season, though he has only a 14.7 percent strikeout rate and a 7.7 percent walk rate. If Lopez sticks as the leadoff hitter, he could be a decent source of runs for the final two months of the campaign.
