Mountcastle is 4-for-27 with seven strikeouts since moving up to Double-A Bowie, and he's struggled with transitioning from shortstop to third base, Roch Kubatko of MASN Sports reports.

The sample size is small, but Mountcastle's .882 fielding percentage at the hot corner suggests he's adjusting to more than just better pitching. The 20-year-old hit .314 with an .885 OPS in 88 games with High-A Frederick before being promoted. Dynasty owners shouldn't worry, as growing pains were to be expected.

Gillaspie broke a toe during his Tuesday game with Triple-A Durham and will miss 1-to-2 weeks, so he'll start his White Sox career with Triple-A Charlotte, Chuck Garfien of CSN Chicago reports.

This will delay any shot of him joining the big club in the near future. Gillaspie is batting .227/.296/.357 with nine home runs, 44 RBI and 45 runs scored in 395 plate appearances this season.

The White Sox acquired Gillaspie from the Rays for relief pitcher Dan Jennings, Marc Topkin of the Tampa Bay Times reports.

As a decently hyped corner-infield prospect, Gillaspie has had a steady climb up the minors in the last four years. He's taken a step back at Triple-A Durham this year, though, compared to 2016. The 24-year-old's .227/.296/.357 line is at least accompanied by nine home runs in 395 plate appearances, so maybe he'll show more thump in time. With Jose Abreu at first base, however, Gillaspie merely profiles as mildly intriguing insurance this year, unless Chicago is going to bring him up to the majors immediately as it tries out its young players. Maybe the switch hitter can snag at-bats as designated hitter in the short term. Either way, this isn't a bad chance for the White Sox to take.

Rizzo went 3-for-4 with a double and four RBI during Wednesday's win over the White Sox.

The first baseman now has three doubles, three home runs, 10 RBI, seven runs and an .886 OPS through 12 games out of the All-Star break. With the Cubs beginning to click offensively, Rizzo projects to have a strong second half, and he's already positioned himself to top 30 homers and 100 RBI for the third consecutive campaign.

Joseph could be splitting time at first base with Rhys Hoskins over the final two months of the season, Bob Brookover of The Philadelphia Inquirer reports.

Hoskins is ready for a promotion to the majors, but Joseph has been productive as the Phillies' regular first baseman this season. Neither player is an option in the outfield and both hit right-handed, which leaves the Phillies having to consider a time share at first base. The Phils are willing to trade Joseph, but the market for first basemen is limited at the moment. A trade may have to wait until the offseason.

Goldschmidt went 2-for-2 with a pair of doubles, three walks and three runs against the Braves on Wednesday.

He's been an on-base machine lately, drawing eight walks while collecting five hits in 12 at-bats over the last four games. Goldy is also in the midst of an 11-game homer drought, though, and over his last 27 contests, he's hit an uncharacteristically weak .255 with only three homers while striking out at an increased clip. It's quite conceivable that these last few games are indicating a turnaround in progress, though; it's hard not to believe in Goldschmidt at this point.

Gurriel will start at third base and bat cleanup Wednesday against the Phillies, Brian McTaggart of MLB.com reports.

Gurriel shifted to third base during Tuesday's contest after Alex Bregman exited early with a hamstring injury, marking just his second appearance at the hot corner all season. Because third base was his most commonly played position as a rookie, Gurriel likely has eligibility at both corner-infield spots in most formats in 2017, but he'll probably need to make several more appearances at third base beyond Wednesday in order to retain eligibility next season. Since the Astros are viewing Bregman's injury as a day-to-day issue for now, Gurriel could be back to his normal spot at first base before long.

Calhoun went 1-for-5 with a three-run home run in Tuesday's extra-inning loss to the Indians.

The 29-year-old has been slumping since returning from the break (3-for-23), so Tuesday's three-run shot may be a sign that he is breaking out of his mini slump. Calhoun is power is right on pace with his career marks, but his .234 batting average has severely limited his fantasy value this year. That said, his .270 BABIP remains over 30 points lower than his previous four-year average, so if his luck turns in the second half he could regain standard-league value.

Cron is out of the lineup Wednesday against the Indians.

After a string of four straight starts with lefties on the mound for the opposition, Cron retreated to the bench for Tuesday's series opener, as righty Mike Clevinger took the hill for the Tribe. Cron will sit again Wednesday in favor of Luis Valbuena with another righty in Carlos Carrasco on the mound, so it appears safe to conclude that Cron is still on the short end of a platoon at first base.

Alonso missed time this season with a hand injury, J.J. Cooper of Baseball America reports.

The Mets' first baseman prospect is slashing .265/.330/.507 with High-A St. Lucie this season, including 12 home runs and 15 doubles in 211 at-bats. The power numbers make Alonso attractive in deeper dynasty formats, as he projects as a possible cleanup hitter one day in the big leagues if he can hit right-handed pitchers.
