STL@HOU: Maxwell injured while diving for a catch

HOUSTON -- Astros outfielder Justin Maxwell was placed on the seven-day disabled list Sunday with concussion-related symptoms. To fill his spot on the roster, outfielder Jimmy Paredes has been recalled from Triple-A Oklahoma City.

Maxwell sustained a mild concussion in Tuesday's game against the Cardinals while making a diving attempt in right field. He has not started a game since then, appearing in Friday's game as a pinch-runner.

"He informed first-base coach Dave Clark that somewhere within the sequence where he dove back to the bag or got moving around and his adrenaline got flowing that he had a slight headache," Astros manager Bo Porter said.

That slight headache became more severe, and after being re-evaluated by team doctors, the decision was made to place him on the DL.

"When you start talking head injury and concussion, it's nothing to play with. And this is his third concussion," Porter said. "So from an organizational standpoint, we're doing the right thing by taking every necessary precaution."

Pena out Sunday, Monday due to death in the family

HOUSTON -- Carlos Pena will miss the Astros' games on Sunday and Monday due to a death in the family. Pena and his family are returning to the Dominican Republican, where his wife's nephew drowned.

"Obviously, we need to keep Carlos Pena and his family in our prayers," said Astros manager Bo Porter. "It's a very unfortunate situation."

Pena will not be placed on the bereavement list.

"He should be back on Tuesday," Porter said.

Paredes recalled, scratched due to late arrival

HOUSTON -- Outfielder Jimmy Paredes was originally in the Astros' starting lineup for Sunday's series finale against the Angles. Paredes was recalled from Triple-A Oklahoma City to fill the roster spot of Justin Maxwell, who was placed on the seven-day disabled list with concussion-related symptoms.

However, Astros manager Bo Porter was informed Sunday morning that Paredes would not make it to Houston for the 1:10 p.m. CT start, so Paredes was scratched from the starting lineup, but was available upon arrival.

Paredes was hitting .340 (52-for-153) in 41 games for Oklahoma City with five homers, 14 doubles and 22 RBIs. He also had a .404 on-base percentage and a .569 slugging percentage. This is his second big league stint in 2013.

"We look forward to having him here," Porter said. "The fact that he's played so well down at Oklahoma City weighed heavily on our decision for him being the guy to come up."

Worth noting

• Jason Castro hit his 11th home run of the season on Friday, which is the most home runs by a catcher in franchise history through June 29.

His 11 homers are the most by an Astros catcher in a season since Mitch Meluskey hit 14 in 2000. The club record is 17 by John Bateman in 1966.
