Castro went 3-for-4 with a walk and two runs scored Sunday against the Tigers.

Castro entered Sunday's contest mired in a 7-for-45 slump but broke out to help spark the Twins offense during their 5-0 win. His slash line now stands at .263/.353/.411 with 24 doubles, five triples, seven homers, 34 RBI, 60 runs and 10 steals in 17 attempts over 425 plate appearances.

Polanco left Sunday's 6-3 win over the White Sox in the bottom of the seventh inning as a result of knee pain, Daniel Kramer of MLB.com reports.

Polanco has been dealing with the knee injury for a while according to manager Scott Servais, but the issue isn't considered to be injured-list worthy. The infielder was also removed partially due to Seattle owning a 6-1 lead entering the bottom of the seventh. Polanco can be considered day-to-day heading into Monday's series opener on the road in Boston.

Gelof is out of the lineup for Sunday's game against the Angels.

Gelof has a .579 OPS and 32.1 percent strikeout rate over 73 at-bats in July and will sit Sunday for the second consecutive game. Abraham Toro will receive another start at second base Sunday, while Tyler Nevin makes a start at third.

Frazier is not in the starting lineup for Sunday's series finale against the Cubs.

Frazier is slashing just .146/.205/.220 with one home run, five RBI and a 22.2 percent strikeout rate across 43 plate appearances in July. Salvador Perez will serve as the designated hitter Sunday and bat in the cleanup spot against Cubs right-hander Javier Assad.

Polanco went 3-for-5 with two home runs and three RBI in Saturday's 6-3 win over the White Sox.

Polanco hit solo shots in the fourth and fifth innings before tacking on an RBI single in the eighth. Hitting in Chicago has agreed with the second baseman -- he has three long balls over two games versus the White Sox, giving him nine on the year. He's added a .209/.293/.340 slash line, 24 RBI, 24 runs scored, two stolen bases and five doubles over 273 plate appearances.

Keith went 2-for-4 with a home run, a triple and three RBI in Saturday's 7-2 win over the Twins.

Keith was retired in his first two at-bats Saturday, but then he tripled and homered in the sixth and seventh innings, respectively. Seven of his 11 home runs this season have come in the month of July, as he's found a home at the top of the Tigers' lineup. Keith is hitting .347 in July and has raised his slash line to .259/.317/.411 this season.

Gelof is absent from the starting lineup for Saturday's game against the Angels.

Gelof will get his first day off since June 26, yielding to Abraham Toro at second base. Gelof has logged a .613 OPS and a 35.0 percent strikeout rate in 340 plate appearances this season.

Massey is not in the Royals' starting lineup for Saturday's game against the Cubs.

The lefty-hitting Massey will begin Saturday's contest in the dugout with the Cubs sending southpaw Shota Imanaga to the mound. Maikel Garcia will start at second base and bat in the leadoff spot.

Frazier is not in the starting lineup for Saturday's game against the Cubs.

With left-hander Shota Imanaga taking the mound for the Cubs on Saturday, the lefty-hitting Frazier will retreat to the dugout while Vinnie Pasquantino serves as the designated hitter. Frazier went 1-for-4 with a two-run single and one run scored in Friday's 6-0 win over Chicago.

The Angels outrighted Hiura to Triple-A Salt Lake on Saturday.

Hiura will remain within the Angels organization after being designated for assignment earlier this week and clearing waivers. Across his 19 games in Salt Lake this season, Hiura is slashing .360/.429/.853 with 12 home runs and 21 RBI across 84 plate appearances. That production hasn't translated to the majors, however, as the 27-year-old has gone just 4-for-27 with a 37 percent strikeout rate in 10 games this season.
