Keith went 2-for-4 with a solo home run in Thursday's 12-3 loss to the Twins, which was called after seven innings due to rain.

Keith was a bright spot for the Tigers on an ugly afternoon in Minneapolis. The young second baseman now has consecutive multi-hit efforts, and he's tripled and gone deep during the stretch. Overall, Keith has been so-so this year with a .236 average and .620 OPS, though he's been better from May onward after a rough first month in the majors. There's still potential for a big finish from the 22-year-old rookie.

Gelof went 0-for-3 with a walk, a stolen base and a run scored in Thursday's 5-0 win over the Angels.

The steal was Gelof's 10th of the year. He's picked up two of those thefts during an eight-game stretch in which he's gone 7-for-27 with a 4:13 BB:K. The second baseman is at a .201/.263/.361 slash line with nine home runs, 23 RBI and 30 runs scored over 67 contests, and his 36.2 percent strikeout rate is weighing down the rest of his stat line.

Frazier (thumb) began a rehab assignment with Double-A Northwest Arkansas on Thursday.

Frazier has been on the injured list since June 24 due to a strained right thumb, but he's now been given the green light to test his thumb in a competitive environment. It's unclear how long the 32-year-old will remain in the minors, but a return before the All-Star break remains a possibility.

Polanco is not in the lineup for Thursday's game against the Orioles.

Polanco was given a semi-day off Wednesday in the designated hitter slot and will be out of the lineup altogether Thursday. Ryan Bliss is getting the start at second base for the Mariners.

Horwitz is out of the lineup for Thursday's game against the Astros.

Hortwitz will head to the bench Thursday with lefty Framber Valdez on the mound for Houston. Leo Jimenez will man second base and bat eighth in the series finale.

Semien is absent from the lineup for Thursday's game against the Padres.

It's just the second day off of the season for Semien, who has managed just two hits over his last 36 at-bats. Jonathan Ornelas will handle second base for the Rangers on Thursday while Semien receives some much-needed rest.

Ornelas was scratched from the lineup for Wednesday's game against the Padres.

The 24-year-old was set to receive his second straight start at third base Wednesday, but shortstop Corey Seager's (wrist) late addition to the lineup will push Josh Smith back to the hot corner. Ornelas went 1-for-2 with a walk, a double and an RBI on Tuesday but may not stick around the roster much longer if Seager is fully recovered.

Mateo is not in the starting lineup for Wednesday's game against the Mariners.

Mateo has gone 0-for-7 with one walk and two strikeouts over his last two games, and he will begin Wednesday's contest on the bench. Jordan Westburg and Ramon Urias will start at second and third base, respectively.

Ornelas started at third base and went 1-for-2 with a walk, a double and an RBI in Tuesday's 7-0 win over the Padres.

Ornelas entered the starting lineup as Josh Smith continued to fill in at shortstop for Corey Seager (wrist). Ornelas and Davis Wendzel are covering third while Seager is unavailable.

Lowe went 1-for-4 with a solo home run, scored twice and drew a walk during the Rays' win over Kansas City on Tuesday.

Lowe's seventh-inning walk enabled him to score on an Isaac Paredes double immediately afterward, and his homer in the ninth frame gave Tampa Bay some additional insurance as the team cruised to a 5-1 victory. The 29-year-old has now hit seven home runs on the year, two of which have come in his last two games.
