TORONTO -- Major League Baseballs new rule on home plate collisions is causing some confusion. Houston Astros manager Bo Porter had a telephone conversation Wednesday with Hall of Fame manager Tony La Russa, currently a special assistant to baseball commissioner Bud Selig. Porter said La Russa told him the league intends to clarify its rule on blocking the plate, and how such calls are challenged and reviewed. "My understanding is there will be a memo coming out that will bring some more clarity to it," Porter said before the Astros played the Blue Jays on Wednesday night. MLB spokesman Michael Teevan said he wasnt aware of any plans for a new memo. Porter telephoned La Russa after Astros outfielder L.J. Hoes was called out at the plate on an infield grounder in the eighth inning of Tuesdays 5-2 loss. That made him the second manager in four days to pick up the phone after a call at home plate. On Saturday, Yankees manager Joe Girardi spoke to Joe Torre, an MLB executive vice-president, over his concern there was "confusion to the rule." New Yorks Francisco Cervelli was called out trying to score against Toronto, even though Blue Jays catcher Josh Thole was straddling the plate before receiving the ball. "I believe this is going to be the toughest overall for (umpires) to get right all the time," Girardi said after Saturdays 4-0 loss to Toronto. "To me, its a vague interpretation of what blocking home plate is and I think it needs to be in writing." In January, baseball adopted a new rule on plate collisions on an experimental basis for this year. Under the rule, catchers are prevented from blocking a runners path to the plate unless they have possession of the ball. "Its a rule that was ... agreed to late, and I dont know if everything has been completely ironed out," Girardi said Sunday. Porter said he planned to speak to the umpiring crew during the exchange of lineup cards before Wednesdays game to ask for their interpretation of the rule, and the challenge process on those plays.

The top-seeded and top-ranked Williams dropped three consecutive games to fall behind 4-3 and then ripped seven straight points to right the ship in front of a sellout crowd at Stanford. "It wasnt very easy," Williams said. "I tried to do the things I worked on. Im feeling really good. Im not out of breath, so yeah." Williams assured herself of a 200th non-consecutive week at the top of the ladder while Ivanovic will return to the top 10 for first time in over five years. Andrea Petkovic ended Venus Williams run in the tournament, beating the former top-ranked player 6-1, 3-6, 7-5 in the quarterfinals. She gets a shot at Serena Williams on Saturday afternoon. "You dont ever have the feeling you have something under control when you play either of them," Petkovic said. "They can hit so hard, and play consistently well. You always have to be on your toes." Following a shaky start, the 25th-ranked Venus Williams picked up her game in the second set and appeared poised to take over the match. The 18th-ranked Petkovic rallied in the third set, taking leads of 3-1 and 5-3, to beat Williams in their first meeting since Luxembourg in 2012. "I was not as on as I was on previous days," Williams said. "I had to fight through that and I think I almost did that. But she played the last two points better." Pettkovic, making her debut in the tournament, is looking for her third title of the season.dddddddddddd. She also reached the semifinal at the French Open. "I played one of my best games in the third set at 5-5," Petkovic said. "Before that it was a weird match. There were so many momentum changes and so many ups and downs, I felt like I played four different matches in one." The Serena-Ana match was similar as Ivanovic dominated the first set before Williams turned it around in the second set. The third set took on a life of its own. Both players simply refused to go away and battled through long rallies and silly errors. Serena served for the match at 5-4 but Ivanovic denied her. Serena broke back and used a pair of aces to take a 40-0 lead before ending it when Ivanovics return went just wide. Varvara Lepchenko took care of qualifier Sachia Vickery, 6-1, 6-0, to earn her 400th career win, which includes all levels. "It was hard to play someone from the United States who I know very well," Lepchenko said. "Ive practiced with her often before. I knew this match would be mentally tough but was just trying to play the best tennis I could." She will meet third-seeded Angelique Kerber in Saturday nights semifinal. Kerber topped Garbine Muguruza, 6-2, 6-1. "She is definitely one of the tougher lefty opponents out there, so I will have to play and fight for every single point," Lepchenko said. "Im going to stay focused on my game and hopefully things will work out well for me." ' ' '
