Polanco (hamstring) shifted his rehab assignment to Triple-A Tacoma on Tuesday, playing seven innings at second base and going 1-for-3 with a double, a walk and a run in a loss to Las Vegas.

It was a feel-good night all around for Polanco within the context of his recovery, as he handled the bump up in affiliate from High-A Everett well and logged his longest time on the field yet over his first three minor-league games. The veteran infielder is likely due for at least one more outing with the Rainiers before activation is considered, and in addition to the apparently improved condition of his previously ailing hamstring, it's encouraging Polanco has reached safely in all three rehab games thus far.

Schneemann will start at shortstop and bat seventh in Wednesday's game against the Mariners.

Schneemann will make his fifth straight start and will occupy his third different position over that span. The utility player has already been used at six different positions since being called up at the beginning of the month and is maintaining a 1.115 OPS over his first 33 big-league plate appearances.

Mateo went 0-for-3 with a walk and a stolen base in Tuesday's 4-2 loss to the Yankees.

Mateo remains in a slump -- he's 0-for-10 over his last four games -- but he's picked up two steals over six contests since he returned from a concussion. With Jordan Westburg (hip) leaving Tuesday's game early, Mateo's playing time could rise in the short term if his teammate is forced to miss additional games. Mateo is at a .231/.280/.431 slash line with four home runs, 16 RBI, 22 runs scored and 12 steals across 48 contests this season.

Loftin went 1-for-3 with a two-run home run, a walk and an additional RBI in Tuesday's 7-5 loss to the Athletics.

Loftin hit his first career homer off Hogan Harris in the second inning, tying the game at 2-2. While Loftin has seen steady run at second base, he entered Tuesday on an 0-for-14 skid that could jeopardize his playing time. He's slashing .253/.351/.304 with 12 RBI, 13 runs scored and no stolen bases over 95 plate appearances this season. Michael Massey (back) began a rehab assignment Tuesday, so Loftin's time in a starting role -- and potentially in the majors -- could come to a close when Massey is ready to return to the Royals.

Gelof went 2-for-4 with a three-run home run, one stolen base and two total runs scored in Tuesday's 7-5 win over the Royals.

Gelof took Alec Marsh deep in the fourth inning to provide the Athletics with enough offense to weather the Royals' comeback attempt. This was Gelof's third multi-hit effort in his last seven games, though the homer was his first since June 5. The second baseman is starting to put together better at-bats, but he's still at a .195/.250/.335 slash line with six homers, 18 RBI, 20 runs scored and eight stolen bases over 54 contests this season.

Lopez is out of the lineup for Tuesday's game against Houston.

Lopez will avoid a matchup with southpaw Framber Valdez on Tuesday. Instead, Danny Mendick will bat ninth and play second base.

The Angels activated Drury (hamstring) from the 10-day injured list Monday.

Drury was sidelined for nearly six weeks of action with a left hamstring strain but is ready to rejoin the Angels after playing in six rehab games. Most of Drury's starts with the Angels will probably come at second base, but first base, third base and designated hitter are options, as well.

Valdez is out of the lineup for Monday's game against the Blue Jays.

The lefty-hitting Valdez will get the night off while the Blue Jays bring southpaw Yusei Kikuchi to the bump. The freshly activated Romy Gonzalez (hamstring) will get the start at second base in place of Valdez.

Massey (back) will begin a rehab assignment Tuesday at Triple-A Omaha.

On the shelf with a low back ligament sprain, Massey received an injection May 31 and appears to have responded favorably. He was cleared to resume baseball activities early last week and has checked out fine after steadily increasing the intensity of his hitting and running over the last several days. The Royals haven't determined how long Massey's rehab assignment will last, but he may only need two or three games with Omaha to get his timing back at the plate before potentially making his return from the 10-day injured list as soon as this weekend.

Polanco (hamstring) started at second base in High-A Everett's win over Eugene on Sunday and went 0-for-1 with two walks before being replaced defensively in the bottom of the fourth inning.

Polanco was able to take another step with his time on the field, even if it was relatively brief. The veteran has reached safely in each of his first two rehab games, and he's now poised to shift his assignment to Triple-A Tacoma when the Rainiers resume play Tuesday.
