MLB notebook: Porter hired as Astros manager
The Astros hired Bo Porter as their manager.
Porter, who was the Nationals third base coach this season, replaces Brad Mills, who was fired last month. Tony DeFrancesco has served as interim manager.
The 40-year-old Porter previously has worked as Arizona's bench coach and third base coach for the Marlins.
He played parts of three major league seasons with the Rangers, Cubs and Athletics.
Indians fire manager Acta
The Indians fired manager Manny Acta after the team collapsed from contention.
Acta, hired by Cleveland in 2009 after two losing seasons as the Nationals' manager, couldn't stop the Indians from falling to last place in the American League Central. They were within three games of first place July 21 before losing 21 of 25 and eventually sliding to last.
Acta went 214-266 in nearly three seasons with the Indians, who are just 21-50 in the second half this season. He had one season left on his contract.
Bench coach Sandy Alomar will replace Acta for the last six games of this season.
Tigers' Scherzer to miss next start
Tigers right-hander Max Scherzer will miss his start Friday because of a lingering problem with his throwing shoulder, leaving Detroit without one of its top pitchers in the middle of a close division race.
Rookie Drew Smyly will start in Scherzer's place at Minnesota.
Scherzer described his injury as a muscle strain.
Greenberg to get 1-day chance
Adam Greenberg faced one pitch in the major leagues, a 92 mph fastball that struck him in the head and changed his life. More than seven years later, the Marlins are giving him a second chance.
The Marlins said they signed Greenberg to a one-day contract, effective Oct. 2, and will play him that day against the Mets.
Greenberg made his big league debut for the Cubs on July 9, 2005, against the Marlins, getting one plate appearance but no official at-bat.
Giants' Wilson ahead of schedule
Giants right-hander Brian Wilson is scheduled to throw Oct. 19 for the first time since Tommy John surgery April 19, and the always-confident closer insists he will be full strength by spring training.
Wilson, the 2010 major league saves leader with 48, spent his third day on the field Thursday doing agility drills and light baseball work stopping balls rolled his way.
Rangers' Darvish feeling better
Yu Darvish is planning to throw off a mound Friday for the first time since skipping his last scheduled start for the Rangers because of neck stiffness. Darvish threw long toss Thursday and reported a “marked improvement” in how he felt.
