Herrera (head) will start at catcher and bat ninth Saturday versus Houston.

Herrera had to make an early exit from Friday's contest after getting hit in the head by Kyle Tucker's backswing, but the 27-year-old backstop appears to be fine entering Saturday's game. Since Aug. 20, he's gone 4-for-22 with four RBI and two runs scored.

Del Castillo isn't in Arizona's lineup for Saturday's game against the Astros.

With Yusei Kikuchi slated to start for Houston, the lefty-hitting Del Castillo will retreat to the bench Saturday. Jose Herrera (head) will fill in behind the dish and bat ninth.

Amaya isn't in the Cubs' lineup Saturday against the Yankees.

Amaya will get a day to regroup after going 0-for-9 across his last three games. Christian Bethancourt will take over behind the dish and bat ninth.

Arizona manager Torey Lovullo said following Friday night's game that Herrera (head) "got through his testing just fine," MLB.com reports.

Herrera was accidentally hit on the top of his helmet by Kyle Tucker's backswing and removed from Friday's game. The manager added that Herrera is penciled into Saturday's lineup. According to Lovullo, the catcher lobbied to remain in the game, and that his removal was strictly for precautionary reasons.

Herrera exited Friday's game against Houston after being hit on the top of his mask by a backswing, Matt Kawahara of the Houston Chronicle reports.

Kyle Tucker accidentally connected with Herrera's mask in the fifth inning. The catcher exited the game after being assessed by trainers on the field and was replaced by Adrian Del Castillo.

Realmuto (knee) exited Friday's game against the Marlins, Scott Lauber of The Philadelphia Inquirer reports.

Realmuto remained in the game briefly after fouling a ball off his left knee in the second inning. However, he was lifted in favor of Garrett Stubbs in the fourth frame. The severity of the issue is unclear, but the Phillies will likely be cautious with the 33-year-old catcher given their big lead in the NL East.

Del Castillo is not in the starting lineup for Friday's game against the Astros.

The lefty-hitting Del Castillo will begin Friday's contest in the dugout with Houston sending southpaw Framber Valdez to the mound. Since being called up to the big club Aug. 6, Del Castillo is slashing .277/.347/.446 with three home runs and 14 RBI across 72 plate appearances. Jose Herrera will start behind home plate and bat ninth.

Fortes is out of the lineup for Friday's game against the Phillies, Kevin Barral of FishonFirst.com reports.

Fortes started the previous four games but will take a seat after going 7-for-14 with two doubles, two RBI and three runs during that stretch. Jhonny Pereda will step in behind the plate to catch for Edward Cabrera.

Bart was activated from the 10-day injured list ahead of Friday's game against the Nationals.

Bart returns in the minimum time from a left hamstring strain. He's had a post-hype breakout this year, slashing .272/.347/.497 with 12 homers in 63 games for the Pirates.

Tait is slashing .272/.313/.466 with five home runs in 27 games since getting promoted to Single-A Clearwater.

Tait's numbers are fantastic, but they are even more impressive when factoring in his age -- he turned 18 on Aug. 27. The lefty-hitting backstop slashed .321/.377/.500 with six homers and five steals in the Florida Complex League before getting promoted, and he has a chance to shoot up prospect lists, especially real-life rankings, in the coming years.
