The Astros promoted Diaz from Double-A Corpus Christi to Triple-A Sugar Land on Tuesday, Chandler Rome of the Houston Chronicle reports.

Diaz makes the jump to Triple-A after slashing .316/.367/.504 with nine home runs and 48 RBI across 267 plate appearances at Corpus Christi. At Sugar Land, he'll be part of a catching group that includes one of the Astros' other top prospects in Korey Lee. Since Diaz also made starts at first base as well as the corner-outfield spots during his time at Corpus Christi, Lee still appears likely to see most of the work behind the plate.

Grandal (back) progressed substantially over the weekend, but he is expected to go on a rehab assignment prior to being activated from the injured list, Scott Merkin of MLB.com reports.

Grandal stayed in Chicago for the team's weekend series at Houston to receive treatment. General manager Rick Hahn was positive when speaking about the progress Grandal made in that span, implying that Grandal would be reevaluated in the middle of this week with the potential of resuming batting practice as well as playing in sim games. Hahn also made clear that he prefers Grandal to complete a rehab assignment prior to being activated. That likely puts Grandal's return in early July at the earliest.

Perez went 2-for-4 with a two-run home run in Monday's 6-2 win over the Angels.

Perez went 0-for-8 across his last two games, but he snapped that small skid Monday. His biggest hit was his eighth-inning two-run blast to give the Royals a three-run lead. The catcher has homered five times in 18 games in June while batting .257 (18-for-70). For the season, he's up to a .212/.252/.428 slash line with 11 long balls, 34 RBI, 25 runs scored and 13 doubles in 234 plate appearances.

Jansen (finger) hit off a tee and played catch Monday, Arden Zwelling of Sportsnet.ca reports.

Jansen was cleared to perform minimal baseball activities last week and was able to ramp up his activities Monday. It's not yet clear when he 27-year-old will be able to return from the injured list, but he's made good progress recently.

Stassi isn't starting Monday's game against the Royals, Jeff Fletcher of The Orange County Register reports.

Stassi will get a breather after he went 1-for-7 with a double, an RBI, a walk and a strikeout over the last two games. Kurt Suzuki is starting behind the plate and batting seventh.

Gallagher (hamstring) was reinstated from the 10-day injured list Monday.

Gallagher began a rehab assignment in late May and hit .182 with two homers, a double, five RBI and three runs over 10 games at Triple-A Omaha. He'll provide additional depth behind the dish for the Royals now that he's back to full health.

Kirk isn't starting Monday's game against the White Sox.

Kirk started in the last five games and went 4-for-16 with a home run, a double, four runs and three RBI during that time. Vladimir Guerrero is serving as the designated hitter while Gabriel Moreno starts behind the dish.

McGuire went 1-for-3 with a walk and a double Sunday against the Astros.

McGuire was in the lineup for the first time in the White Sox's last three games, previously giving way to Seby Zavala. He responded to the opportunity with a one-out double in the second inning, but he was ultimately stranded there. McGuire has a modest five-game hitting streak and has also tallied three doubles in that span, so it's possible he begins to reclaim playing time with Yasmani Grandal (back) sidelined.

Higashioka went 1-for-3 with a solo home run in a loss to Toronto on Sunday.

Higashioka hit one of five New York homers in the contest, swatting a 426-foot solo shot in the sixth inning. The backstop didn't go deep in any of his first 34 contests this season but has since left the yard in three of his past four games. Over that stretch, he is batting .313 (5-for-16) with four homers, seven RBI and five runs.

Mejia isn't starting Monday against the Yankees, Marc Topkin of the Tampa Bay Times reports.

Mejia will get a breather after he went 5-for-8 with a double and two runs over the last two matchups. Rene Pinto is starting behind the plate and batting ninth.
